After reading this article on the
I understand that the loudness control
can never be switched out of the circuit!
And the V1700 was a faulty design in
that is caused damage to loudspeaker tweeters.
If both are true then surely this
cannot be a very good amplifier - yet you say it is? Please
help me understand.
The loudness (when switched out) is
not present on the V1700 because the mentioned network
C708-R710 simply inserts a 1Mohm resistor parallel to the
input (before the volume control) above 1000Hz and this, if
the source that pilot the amplifier has an impedance lower
than 10KOhm (as it normally happens) it does not involve any
variation on the frequency response. Absolutely unfounded
also the possibility of damaging the tweeters that is common
to all the amplifiers when used in clipping. The only true
limit of the V1700 is the sizing made only for nominal 8Ohm
loads, which therefore forces attention to the heating when
driving loads of 4Ohm otherwise it may break the amplifier
and in this case the woofers (not the tweeters…) are also at

unfortunately also this, a mixture of pride and envy. Care
must be taken.
what are the binding posts on your amp? Power? Integrated?
Din or bare cable?
I hope you're fine !
I have a topic which is not very clear in my mind : the
position of the cables !
Wheter or not the amplifier is on the ground, should I :
- put the cables on the ground ?
- put the cables on the ground with a carpet below ?
- hang up the cables ?
I currently put my cables on the ground (my Receiver also)
but it seem's that if I put something between the cables and
the ground the sound seems quite different !
Thanks in advance for your advises,
cables ever on the ground
(220V) cable of receiver on the ground…all others 220V cable

I wonder if
grundig box 650 should be on the BF1, or better on the
counter. (As far from the wall). In your opinion, is better

cover of cotton to the speaker cable?
missing one information: how much the distance from your ear

Grundig cable is better that Vivanco, and better is
listening box 650 with grilles…
of ear to wall behind is 1 metr.
Box 650 pro can BF1 to listen to, or better on the shelf?
Better on BF1 very near to rear wall but with drappes on
this wall (see photo of italian forum here for example:
In your room will be better 850a and 1500a.
on your side in the technical tests, we can see that
the V1700 should be +1 +1 bass and treble. Is the system of
box 650 professor will be the same as the box 400?
“no carico” mean with box400 disconnect
“con carico” mean with box400 connect
V1700 should be +1 +1 bass and treble ever
Maybe for you is
little surprising is I heard something about you
I heard many good things about vintage
grundig system, so decision make one for myself.
So far ordered amplifier Grundig Fine Arts
A9000 and V1700 also bought from you cd 7500 ver.1
At this moment have Dali 505 2 way 4 ohm
speakers 92 db efficienty.
In future want to buy grundig 650 pro,850
pro or 1500pro speakers. But I need time to find somewhere
in good condition with good price. I don’t know yet is it
that system want to put in,will be between
20 or 30 square metres. I not sure yet.
I suppose is v1700 could be to week for Dali
that is why bought A9000
My question is:
A9000 probably still fitted oryginal
STK3102 ver.4 (not coming yet) is it big risky connecting.
Dali. What is your opinion and what I could
to do best at this moment?
A9000 is’t a CCI amplifier and
sound very worse respect V1700, V7000, V7200 etc…
With your Dali loudspeakers you
can use V7000, V7200 or V35 or some receiver “large series”
Grundig…but when you know the room dimension I advise to
search immediatly a right Grundig box.
Also use V1700 with 4 ohm
speakers but not with high listening level…
Hello. I am your big fan of Polish.
I am a happy owner of the system
GRUNDIG (v grundig 1700 CD 7550, the original cables)
Now I bought a wonderful Telefunken tl
800. Unfortunately, I had to replace some speakers (tweeter
and woofer). After disconnecting the cables I do not mark it.
Do you have any photos of the interior?
Do you find
here the schematic:
Hello. What is the best amplifier to TL
800? Grundig v 1700 is probably too little power. Maybe
grundig v 7200? Or maybe something from the stable
Telefunken? Telefunken 6040 opus? Maybe some sansui?
Tfk amplifier are not CCI…V7200 is good or also V7000 or
some receiver Grundig 20-25-30-35 etc.
have a question. In your Telefunken TL 800 how long speaker cable you have? Do
you have full length or you cut off to 4m?
Have a nice
cut cable for maintain the original state...
Massimo, thank you for reply. Can I have one more question? My pair of TL 800 I
bought from my colleague, who read somewhere in Internet, that he should cut off
ori speaker cable to 4m length.... I'm so pissed off, becouse it's very hard to
buy TL 800 with factory lengt speaker cable. Could you tell me, in what
amplifier and cd I should start to listening these speakers? On LT/Grundig Day's
in Ravenna I saw that TL 800 are playing with LT amplifiers.
CCI amplifier are good to listen TL800…
However these speakers are not a “meeting speaker” but a “single listen speaker”
Hope you're fine.
I'm still interested by your last
amplifier. I just wonder what could be the différence with my favourites Grundig
: R25, 30 and 35 ( which sounds better with my ears than the v1700, R20, R45,
The frequencies response is more
streight with your amplifier, and I think it could be a first difference but may
be there is some other différence ?, and by the way is your amplifier able to
drive any kind of loudspeakers ?
Thanks in advance,
The difference is partly in the linearity and partly because a LT amp is a NEW
full CCI amplifier...
Objects that are 35 years old are often with chassis/circuit not like original
CCI condition...and this cause a worse sound.
As i said on last mail, I bought v1700 and t1700.
My room is small so I think about grundig box 400 or 500 to buy,
because you mentioned before that v1700 has impedance problem
with box 300 to drive.
Can the v1700 drive box400 or 500 (not professional) without
Thank you so much for your great information on your web site.
All best Grundig loudspeakers (4ohm) can be used with V1700 but...not
to high listening level. You can buy some Grundig full CCI
receiver (large series) or a V7000 - V7200 if you don't want
I am trying to translate some
of your recommendations - I seems you need to put the
Grundig 1700 on the floor for best results. This looks ugly
in the sitting room. Can I not just put it in a hi-fi rack?
V1700 (and V1850) are “CCI soft optimized”...only little difference
if you put on rack.
Is the Sanyo JA-220 exactly
the same amplifier as the Grundig V1700?
Or are there important differences?
I found my box 1500a.
Unfortunately I'm desapointed by the sound..my 300 or 500 boxes
are better and the sound of the 1500a is à little bit flat and
slow. I know that the 1500a are famous and I think that I should

Thanks a lot for your advices.
I have just a last question,
you mentioned that you didn't advice a change of any
electolytic capacitors but what about the capacitor used by
the tweeter (serial capacitor) ?
I ask you this question,
because I find the treble level a little bit low (and that's
may be the origin of my problem with the 1500a).

The aktiv box must be choose in relation to room dimension…which are
your room dimensions?
Aktiv mod LT are better of your actual system if you use a full CCI

Thanks for your reply. The source
is a rara avis, let's say a computer tuned for audio with a
special DAC. Room dimensions will be around 20 square meters.
Can the Aktiv Box 30 LT Mod sound equal or better than new

Grundig Aktiv box mod have dynamics but at the same time have a
If you goes in Italy to my home you can listen the aktiv standard
version and the aktiv mod version: difference is 3D and gentleness.
Thanks for your kind offer about
listenning speakers at your home. Right now I'm in Valencia (Spain)
but planning to move for living to Zurich, in that case we will
be closer. IMHO Genelec monitors are too bright, I don't
understand how people can mix anything with them. Regarding the
harmonics, which instruments will be better to listen for
testing harmonics? I said that because there is an harmonium at
my family which has been restored. It will be difficult to
recorded it properly but maybe I can get some music already
Thank you very much for your quick
I vacuumed the medium speaker
and it was ok! Regarding the amplifier, I read on your
website that V7200 in "only partially CCI", so not as good
as V7000 or V1700. Now, V7000 I do not find on ebay, but I
do find V1700 - does this one match the 2500a? Because I see
it supports 8-16 ohm, and the speakers are 4 Ohm.
Thank you very much!
I recently bought these
speakers used. I would like to ask you some questions, if
you are so kind to answer.
The medium speakers have their
dome tilt in (pushed).. is it ok to use the vacuum cleaner
to bring it back to the original shape?
You can try...and also with adhesive tape.
Also, the original stands, how
high should they be? 36 cm or lower? Can you recommend a
good stand for them?
I would also like to purchase
an amplifier for these speakers and I have the possiblity of
purchasing a Grundig SV1000 smaller amplifier (together with
tuner ST1000). You think that is good fit for these speakers?
Thank you very much in
There are better amplifiers in old Grundig
production years 75-79 or years 84-85.
You can search all receivers Grundig large
series or amplifiers like V7000, V7200, V30 or
some Grundig “compact” like rpc500-600-650 etc…
I am from Slovenia and would like to know if there will be some
meetings this year-2014 in Italy or Austria, Germany... Just now I
am looking to find some Grundig items on ebay which would build my
new musical system... My room is app. 3,6x4 m and would like to know
which boxes would be best in combination with CD 7500, V7000,
PS1020, T7500 ( if I will be lucky ... ). I hope I could hear some
day your presentation near Slovenia or maybe in Ljubljana if you
have plans to come to our Hi-Fi show which is every year (also in
Zagreb )... Thank you for your reply. Regards, Ales.
thanks for your e-mail.
Next meeting will be 10th May 2014 in Ravenna (Italy). Let me know
if you want to participate and I'll give you the exact address and
some direction: you are welcome. For your room size, in case of
bookshelf installation, I would suggest Grundig Box 300, 350 or 400;
in case of stand installation Grundig Box Professional 650prof or
850a prof; in case of floor installation Grundig SL1000. At the
moment, there are no plans for presentations in Slovenia ot Croatia
but, if you can collect some other poeple interested in my meeting,
I will try to organize it.
Thank you for answer
I was quite active on ebay
to find the best from what you suggest... I hope in a
short time I will complete my Grundig system and than
enjoy in that transparent music...
Here I am asking you to
check attached pdf file - my room and give me your
opinion about speakers to fit...
I always like to read on
forum about Grundig story...and CCI... I like your
approach to the subject... :-)
Warm regards from
Almost "Grundig" Ales...
For good results in your room you can test 650prof , 300, 400 or

I usually listen aktiv box after the CCI modify... :-)
For cd player this is a very good solution for CCI mod.:
Good Easter to you and your family
you for the info. But the opportunity is gone, somebody
bought it before me. But I would like to ask about the older
V5000 and V1000, V2000 - they are good? I have now chance to
buy V5000 for $215 USD, and I dont know is it good price or
searched your Grundig Story, but I dont understand italian,
so I dont know if I get it right… I dont understand if you
were saying the V5000 is good or bad (the same goes for
V1000, 2000) ?
I have a Grundig setup. V20, V35 CD, Grundig Professional 650. Please,
let me know if you can apply a CCI [partial or full] modification for an
external DAC, in this case Lavry DA10, for a full CCI solution.
Many thanks in advance.
Which is better? PS1010 or PS1020?
Or is it any other that better?
Very similar sound, I prefer ps1020 if totally original and
complete and with M85G +N91G Shure
a great pleasure to read about you dicoveries on your website.
Thank you for sharing your knowledge.
currently looking for an amplifier/receiver for my system. I was
considering Grundig R35.
you think it's a good choice for Grundig 650 Professional speakers
not, what else would you recommend?
prefer to have the radio tuner and amp in one box, but if it's a
solution then I'm willing to buy them separately.
Thank you in advance and warm greetings from Poland,
35 is a great solution if not tampered...
listen to you!
Thank you for your recommendation.
Just one more thing I wanted to know.
I have the Shure M85g head on PS1020 and am looking for the
right needle for it.
I couldn't find the original, but I found a replacement N91g -
that has a spherical cut and weights 3 grams.
Is it the right one? Is the weight appropriate?
The original needle for
M85G is N91G (made in USA...not made in Mexico...) that have
with tracking force range 0.75 - 1,25gr.
For best sound you can
Other possible needle
is N75GT2...have the same moving equipment

Thanks in advance
I modify several cd player models with CCI implementation. You can
choose a model and the modify cost (independent of model choose) is 500
eur. The result is the same (if frequency response is flat...) a full
CCI cd player (and with remote control!).
I advice like basic to modify some models of Marantz cd player like (for
example) this http://motxam.interfree.it/cd6004.html
|Dear Massimo is grundig box active 50
as good as 40 and 30?
On Aktiv 50 must doing a little modify DIY for improve it and reach
similar result like aktiv 40: the frontal grill is fixed to box with 6
pressfit grill-guides...you must remove (from grill) the two pressfit
present in middle point of grill.
However I advice the aktiv box only with CCI mod...there is a big
difference...you can find comment on Italian forum...
Without mod CCI I advice much more the passive solution.

Lats night i
came across your webpage,great reading.
Frankly i stay on it
for a few hours
reading and searching for Grundig gear.I know
about old Grundig amplifiers ,good sound for
little money. Even today some Grundig
stuff can be found in Serbia. I found Grundig
650B loudspeakers ,i am
thinking of buying them,i hope they can be used
with mine 6C33C tube
What is your opinion,i dont know nothing about 650B
impedance graphs and
sensitivity,hope they are not heavy load for tube
amplifier. Also hope they can be used on stands? I see
they are bookshelf
but i dont think they can be
put inside some shelf,or?
Here on the link below you can see
those 650B,any advise from you is welcome.
On picture you can see mine
Best regards. Dejan xxxx
650b are 4 ohm loudspeakers...like to your amplifier?
Thanks for reply. I already tried my amp with few 4 ohm big
loudspeakers and it drive em very well,6c33c tubes can drive heavy
loads due to their low internal resistance and also can deliver good
current. Btw o can buy in Serbia Grundig r35,v1000, V2000 and other
Grundig amps for 25-45 euros.
I hope 650 b is good stuff,will hear em next week. Do you know. That
in one hotel in my town,there are almost 100 audiorama speakers
hanging from the ceilings of halls,restaurants etc.
If you can buy Receiver35 I think that you don’t connect more
your tube amp...:-)
Xc65 is excellent preceiver but frequently defective...check
functioning if possible...
So it seems R35 is better solution? I see that you dont like tube
amps:) i also think active boxes also can have parts that are aged,like
power supply capacitors.
Btw my wife is now enjoying in San Remo on medical meeting
while i am freezing at home,no heating till tomorrow.
Receivers are one of better Grundig full CCI solution...If you
will compose a full CCI system (with also CCI source) you will
thanks me :-)
Just to share something with you.
Yesterday i went to visit a high end audio shop in The Hague (Netherlands)
to listen to a 150.000 euro hifi set and Pink Floyd Dark Side of the
The guy who owns the shop also has a Pink Floyd band and he played last
evening at the Peace Palace 100 year opening event, which was really
However, i listened to the whole record in the shop. Although the sound
was good with a wide, deep and high soundstage, it sounded compressed
especially for mid/high frequencies. The high hat determines the whole
timing of Dark Side of the Moon and it sounded flat and distorted.
When i came back home i listened to the whole CD on my Aktiv 50
Professional, CD 35 set up (no Grundig preamplifier yet unfortunately)
and the difference was like day and night.
My setup has cost me about 200 euro and it beats the 150.000 high end
set (see picture) hands down. The difference is in musicality and
The other difference is that the audience of people in the room didn't
express any emotion at all. The live concert was much better!
Now i am going to invite the owner of the shop to my house and let him
listen. He is a very nice guy, wonder what he will say.
I know the difference...:-))

I am a
long-time fan of You from Poland. After reading Your website
I've decided to give a try to Grundigs. Currently I Have
Grundig V4080, Grundig Box 850a and I am also using Apple
AirPort. Couple days ago I've bought Grundig PS 1020.
Unfortunately it turned out that stylus is not original and
broken (Cartridge is Shure M85G). Any Idea where to buy
original stylus (perhaps You have some for sale?). Can I
connect my turntable directly into V4080 or should I use
preamp (I am short on cash as I am not working yet,
currently studying)? Grundig PS 1020 has DIN output and
V4080 has RCA input so I bought DIN/RCA adapter - will this
be a huge quality loss?
Dear Massimo I have another
question to You:
What do You think - Is it
necessary to use low-pass analog filter after D/A conversion with
oversampling in DIY cd player when I connect it to CCI amplifier?
I think that CCI eliminates
HF frequencies from signal, but I wanto to make sure...
Thank you for Your site, it's

Before a CCI amplifier you need a CCI cd player...
Is cable from Grundig Audiorama
box 310 enough good for 850 or 1500 a prof. ?
I am 60 years old now and
have just read your website. I live in Malta and Finally I have
found someone who discovered these Gem Amplifiers!!
Massimo, 40 years ago
when I was 20, I was changing amplifiers like crazy. I became
friends with a dealer who used to allow me to take home and try
Sansui, Pioneer, Yamaha, etc.. always top of the line models. But I
was never satisfied. There was something which kept me changing and
trying. All these would amplify base at 100HZ and treble at 10K,
useless controls too to adjust a little to make up for room acustics
and recording issues. Besides the sound sounds clean but with no
debt and metallic.
I used to visit Hanover
Fair every year and once stayed with a family, Peter was the husband
and Karen the wife, Bianka and Dirk the kids.
heard music in the background which sounded like I never heard
before. Where are the speakers,
I asked myself ? Where is the amp?
The speakers were on the
window sill hidden behind a curtain. The first time I saw two really
small Grundig Boxes.
The amp was in a
cupboard, a small R35. I could not believe the sound was coming from
those two small boxes.
asked Peter if I could put the volume up a bit, and I could not
believe my ears!
I went to Grundig Agent,
I saw and heard the R45 with Box 1500 and 2500 (not active)
I read the R45 User
manual and for the first time in my life (I am en electronics eng.
City & Guilds 433 in Electronic Systems) I saw test which made sence
Distortion is measured
from the pre amp in to
the speaker out. i.e. the preamp which is the most
important is included in the equation.
Distortion is measure
at 40HZ, 2000HZ and 20,000HZ and this amp would give you .02 all the
way up to 55RMS at any frequency from 40 to 20K.
The Japanese at the time,
even the best would give you distortion at 1k and the preamp is
never included in the tests.
it. Oh God! This is the sound I had been looking for, for many
see attached for imputs TA, TB, Bass/Mid/Tb controls etc.
IS THE SOUND I ALWAYS WANTED
Since then, the arguments
I had with many dealers and friends of mine are endless.
Same as you, I invite
anyone who want to bring his amp and speakers to my home ad do
My friend the Dealer,
once brought the best Pioneer 999 and the best Bose speakers he had.
Close but not quite, –
the base would not go down as smooth as silk as the Grundig
Amp/Speaker combination can be at the lower ends.
And the treble dimention
or spaciousness and harmonics would not extend to the top end and
were not so sharp, smoothly and clear either.
However after doing some test I discovered the following;
If I feed the
pre amp output of the R45 into the Main Amp of the Pioneer and still
use the Bose Speakers – the sound of Pioneer/ Bose combination would
sound almost identical to the Grundig R45/Box 2500 combination !!!
Some 10 years ago, with
the introduction of DVD and Dolby 5.1, I bought a Yamaha A1. It is a
good amp but no good for stereo. Sound fields make the music sound
In stereo, Base depends
on the support of a sub woofer, midrange is reasonable but the high
end is not acceptable to me.
It is good for watching
and hearing DVD films with Bombs, Planes and Cars rushing all the
way around the room!!!!!
For Music it is a
hopeless investment and a waste of money.
Anyway, I did the same
test. I fed the R45 preamp into the Yamaha a1 left and right
channels (effects off.)
Believe me, the main amp
of the Yamaha is a good amp. (not pre amp)
I changed the Yamaha A1
rear setting to 4 ohms and connected the Grundig 2500 speakers.
You get the same clean
and clear spacious musicality of the Grundig and it has the capacity
both the base drivers at
40HZ nicely, midrange is clean and clear and beautiful too, and any
treble at 15K and harmonics above are reproduced as easily as the
Main Amp of the Grundig R45.
share with me if my conclusions are correct.
I have read your
explanation of CCi.
do not know what CCI really means technically – and would sincerely
appreciate if you can explain in technical language the details,
because I have been curious all my life about what makes my R45 so
also think that it is the “Pre Amp” of the Grundig which is the KEY
to the beauty of the sound which makes these Grundig old units
Am I right.
I attach the graphs of
the R45 – not how the distortion at 40, 2k and 20K remains
negligible all the way up to 55RMS.
other question is, if I may take more of your valuable time;
Which Pre-amp and/or Amplifier in the Grundig range is better than
Is the V5000 or the V7000 or the V1700 better than my R45?
R45 is absolutely to blue print speck. And when one of the output
stages failed, I replaced the pair with one that are full speck,
same as the originas, which I ordered specially since no one stocks
them in Malta. . I have now bought a second hand R45 from e-bay too
for 100Euros – so parts are not a problem either.
Massimo, all the best to
you and your work.
I have the Original
manuals and the original circuit diagrams of the R45 and the
2500Professional a speakers.
If you should need
copies, I will gladly send them to you.
that I have called CCI are not correlated
with harmonic classic distorsion but with HF intermodulation
distorsion. The chassis problems that Grundig have (like me) solved
in 1974-1985 period is present in all electronics chassis and is the
first cause for a good or bad sound.
You can read with care my website for more info.
I have bought from
e-bay 2 x Box850 Active, which have not been delivered yet.
This is because I had
already a Grundig SXV 6000 pre-amp.
But is the SXV 6000
good for driving the Active Boxes?
Or should I buy the
Grundig 55X? Because at the moment there are 2 x 55X for sale
Which is the better
of the two for driving active boxes.
What I wish is a sound which is as good or better than the
R45a which I have with Grundig normal Boxes.
Take care and all the best.
The better is XV7500…same circuit of SXV6000 but more advanced
CCI (and then better sound).
I have a question about
amplifier Grundig V4080.
Is it the same as V1700?
Not the same but very similar...
very pleased within your site and all that you said about Grundig. I
am 50 y. old and has more than 25 y. experience within our hobby. My
last system is Kuzma Stabi II, Stogi Ref. VDH Frog Gold, AUdible
Illusions M3A, Pass Aleph 5 and Sonus Faber Cremona Auditor speakers
( I. model). Some times ago I refreshed and serviced Grundig TK 145
De Luxe mag from 1967. and find out it has specific sound that is
choesistent and very real. A also bought Grundig Satellit 208, and
find out that it is outstandig tranzistor. So at last I purchesed
Grundig Box 550 Professional, that I hope to receive this days.
Please let me know something abotu that model of Grundig speakers,
and what is a reason that Grudig speakers like to look Grundig amp
and other equpiment from that time. Friend fo mine that has great
experience in audio and professional audio said to me that old model
of amplifiers from that time had some equiliser within volume
control that added some bas exstension so that could be one of
reason why Grundig speakers from that time play in such manned that
best suited to Grundiq equipment. Please let me know what is
original conection of speakers terminal on BOX 550.
please read carefully my website and you will find a lot of
useful informations. Most of Grundig hifi components from 70ies
to 80ies they are engineered and built in a special way and they
have some technical solutions that nobody today is able to pair.
This is the reason why their sound is the best I've ever found
in any commercial hifi, even compared to the most expensive
high-end systems that I've tried myself (see my website for the
None of the Grundig amplifiers that I suggest in my website has
some equalizer within volume control to add some bass extension.
They have a standard (for those years) Loudness selector but
you have just to leave it unselected.
Box 550 is a two-way speaker for medium-small room with standard
DIN connectors. If you want to listen seriously to a pair of
Grundig speakers you must drive them with the suggested
components and cables (V7000, V35, V1700, CD7500, PS1010,

You are right when mentioned old school like Grundig story
and others brand from that period like 1975. till to 1985. I
started to interested in hifi in that manner latter mostly
during the 1985.y At first I started within Sansui and KEF
REf 101 model speakers and as I could remmebered Marantz 65
MKII. That was enough good sound that I didn't know to
recognised in such way. As I already mentioned my present
system, i find out that I spent many many times and money to
start thinking that I just made circle, and now after more
tha 25 y. in hi fi occupation find out that Grundig was such
succes story than and now. So as I wrote last time I bought
GRUndig Box 550 Profesional in good condition, and after
that few days ago purchased Grundig R200 receiver. I occour
some broom- buzzing in both canel in the begining of turn
on unit, and after some minutes that broom- buzz expire. I
think that could be reason old caps that should be replaced.
Do you have any sugestion which type of caps or old parth
could be recommended for replacing in that case. I find out
that sound of that combination R200 and 550 Profesionall is
preaty plesent and more than that.
Best regards and thanks in advance for reply,
Try to keep on the receiver for 2/3 days....often this is
Please let me know what range of Grundig receiver gama is model
R200. Is it inferior to models R30 R35 or similar series?
regards and thanks in advance,
I'm very fan of grundig speakers, even if I own only two models: super
hifi-box 650 and 850.
I just opened the 850 to check the crossovers, and I was very amazed by
the quality of most components of it, especially selfs, that are big and
nice built. But capacitors are from Frako, which is definitely not the
best caps you can find... so I was intending to replace those, because I
really like a lot those speakers, but I think they could sound even
better once recaped.
And I found your website, and the mysterious footnote, warning that one
never should modify Grundig products... so what about recapping the
crossovers?? Any specific reason not to do so? I did this already one
several other speakers, with great results...
Thanks for your input,
Grundig hifi-box 650 and 850 ("a"
version) are some of the best speaker ever built.
They sound amazing when driven by a
Grundig chain (look at my webpage
for informations about amps and sources to use), better than any
"high-end" loudspeaker today on the market.
I suggest to NOT recap their
crossover: these Grundig speakers are going to sound worse if recapped.
I suggest to recap ONLY in case some cap is faulty or drifts excessively
in capacitance value.
what? I feel very stupid!!
removed the original speaker terminator a few months ago to put in place
some standard (cheap)
Others terminations (different to
standard point-line) are very worse on sound...
to allow connect the speakers with any kind of
cable... and I'm wondering know if I did not reverse the wires!
one yellow and one black, and it looks like bass are far better when I
connect the cable using the yellow cable as negative and black as
positive. But as far a I remember, I paid attention to the way wires
should have soldered on the replacement terminator... do you have by any
chance an advice to check that without opening the speakers? I'd like
not to open them too often, to keep the wool inside in a good placement...
by advance ;)
You can connect a 1,5Volt
battery: when woofer cone comes out the battery + corresponds to
positive polarity of speakers.
what is linear transfer mod? is it possible for a philips cd 650?

concern is the digital playback. good vinyl lps on a rega p2 with

can you offer a cd960 with LT mod?
best regards and greetings from berlin.
the Linear Tranfer modification is a
technical update made by myself and it is possible for the most of the
cdplayers. This modification involves deeply the chassis of the
equipment and it requires the maximum linearity and transparency by all
the hifi chain. This is the reason why the zero oversampling does not
match well the LT mod. For the same reason I strongly suggest to
complete the hifi chain with LT amplifiers/speakers or some old Grundig
amplifiers/speakers featuring a similar chassis technique, see my
website for further details.

agreed that we love some vintage audio, and he said to me only
Grundig man, only German stuff or Sanyo :-) If you don't believe me
listen and visit http://motxam.interfree.it :)))
visited your site and read about this Grundig stuff and I'm
interested in it :)
know I got some occasion to buy Grundig V35 and I got some question.
there any chance that I will hear the difference using the Grundig
CCI with an old non CCI speakers and CD? Or should I transform all
audio to CCI.
is quite important to me because if I have to modify all audio
equipment I'll not buy this Grundig but if there is any chance to "feel"
the difference I'll buy it.
will by very grateful for your help
If we imagine to take a look at a landscape through some windows
(each of them represents a component of your hifi system), we will
see perfectly the landscape only if EACH window is completely
transparent, undistorted and uncoloured. Just one distorted window
can compromise and damage irrevocably the result. This is the reason
why I suggest to listen to a system composed entirely by Grundig or
Linear Transfer components!
For others occasions I

Reading your web site converted me to Grundig, after I had luck buying
Grundig box 250 by pure coincidence. Recently I've had luck and bought
v7000 with t7000. Now, I would like to find 650box proffesional, to
Looking for other Grundig products, I've stumbled across Sanyo JA220
with JT230L tuner for cheap and wanted to hear it.
1. Well, it arrived in the mail, but I don't know is it safe to connect
4ohm 250 box on it? I've tried, just to hear is it working, but I don't
want to burn it. Anyway, the sound was not satisfying (although only for
10 seconds before I disconnected them).
2. And another question - reading many posts on Sanyo ja220 vs Grundig
v1700, I'm still not clear is Sanyo full CCI, or is it inferior to
So far, I like what I hear from Sanyo JA220, altough it's connected to

Thank you for sharing your knowledge of super super Grundig products.
You can drive the box 250 with ja220 but with high
volume can risk to damaging the amp.
The ja220 is very similar to v1700 and full CCI if it wasn't repaired or
for more then 40 years i am
an audio enthusiast and melomane and music player, had for 5 years even
an audio shop in brussels with 2hand equipment and even new , so after
years of trial and error and hearing some amplifiers sounding realy bad
...i must agree with your experiences of most of yours and made some
musician very happy with active box 40s but the v7000 on tads 1102 with
heil tweeters play even better, and so went out a bel canto evo6 that
cosed 5000 euros...against the 100 euros for the grundig, the only amp
that came close was a rogers valve el84 i will soon test the grundig
amps on very high efficiency speakers so to avoid clipping at high
levels, but to be frankly since i listen to the grundigs i listen more
relaxed at low levels and hear all the details, with the bel canto it
was like lots of the mics were distorting or clipping!!!and i got
nervous and thought it was a problem on the records or the radio but no
with th v7000 all came in harmony ,you cannot tell if its a transistor
or valve here , even the bass is tremendous quality for such a small amp
amazing, i use a camtech 8000q aspassive volume with remote so i have
that convenience, and also used a passive active cross over from cerwin
vega that filters the amps at 250 hz to drive subs from jbl or atc with
amazing results, it was far better then the quad 606 who is rated more
watts....there is something with the timbre of the instruments and the
scale that is magic and very realistic, and that is missing in most of
the amps....25 years ago i had the electrocompaniet class a who was
musical beyond the competition, the audio research classic 60 with
yamaha ns1000ms had some qualities aswell but still since i am on the
grundig v7000 i have 5 of them ,i dropped the search for others i also
have the ps 1020 to test , and curious about the cd's,for now i am
running with sony 557 esd and rega io....
so you crazy italien freak most will thingk but for my ears you have
made a big point , and when i am rich i will buy your amplifiers gladly
to test them and would even be glad to sell them to other audiofreaks
old clients customers ...i wish you lots and congratulations for such
courage to make these statements completely non snobisch and honoust and
dam rigcht its looks a bit like the hulda clark protokol in the medical
who cures 95% of cancers with herbs etc but its so cheap nobody wants to
apply it greets and hope to meet you one day a life soon
bart xxxxxx belgium
for your beautiful e-mail. I am happy that you have appreciate my work.
you are a great person ,
because honoustly i was too snob to test an amplifier that even has no
wbt speaker output...and din connections lots of even experienced
audiofreaks would pass for it and even not truy it out, but since your
opinion on the other equipment is about the same then i experienced like
for the rogers or the quads or the B&W's and the krell , i took it more
serious and tried it out another well sounding litlle amp is the myst it
worked even better with the rogers ls3/5a then the classic 60...but i
never tried the grundig on them since its fairly new these experiences ,
and i test about one year before i put out an opinion , i also
appreciate the site of the polish who modifies cd outputs but didn't
truy yet these modifications , except that i like the atc's the mid dome
is amazing and what so strange with a grundig amp that i listen at more
easy listeninglevels so my neighbours are happy , its so clear and high
resolution that you don't need to push the volume loud you can imagine
how deceived i am with amplified concerts most of the time horrible ,
distorted and way too loud since i go to concerts with acoustic
instruments like big symphonies from the year of 5 i am used too good
sound , the grundig activ 40 i sold at a friend who is building violins
...he was astonished by the accuracy of the timbre, he works together
with my cousin who is a professioal violin player and plays aswell on a
guarnerius and also has an absolute hearing so we are all very critical
, i ll let you know more after testing with a 105db/w horn system my
I find that the sound of the amp is much better after upgrading. The
sound is more body and very detailed. Vocal and instrument sounds are
now more real. I can feel that the music has more rythms and is more
The new volume control is also much better than the original one. The
sound levels from the left and right channels are now very balanced even
at very low level. I think this also improves the whole picture of the
music and the image. I hope the new volume control can keep this good
I have also tried the Milty connector and it works fine.
I am very satisfied with the sound of the upgraded amp. Can you advise
whether the upgrading involves change of electronic and/or improvement
on the CCI application. I note that there is a new "foot" at the bottom
of the amp.
Do you recommend to keep the amp "on" at all time? I find that the sound
of the amp is much better 3 to 4 hours after switched on, though the
sound is already very good just after switched on.
I would like to thank you very much for this upgrade and the replacement
of the volume control. I will play more different kinds of music and let
you know more of my listening feeling later.
...the music has more
rythms and is more alive.
This is the
plus of full CCI technologies... music more alive! :-)

I think that

But still wish to ask one question.
If we were to choose speakers from
Grundig brand, then what is the preferred speaker for MA10wifi,
V7000 and V1700
I just know that V1700 requires
speaker with impedance 8 or more. I am also aware that
particular model speaker is dependant on size of room.
But you can advise the readers
like me to guide about matching speaker.
There isn’t “preferred matching” between amps/speakers full CCI…there
is only “preferred matching” amps/speakers/room
dependent to power needed
and right type of speakers
for your room. The V1700 haven’t problems to drive
some 4ohm speakers but not all models: v1700 frequently breaks
to drive box 300…but no problems with box2500a for example.
However all others full CCI Grundig amps have been made to drive
4 ohm speakers…
I get a feeling that (V7000 and
Box 300) and (XV-7500 & aktive 40) are your favourite
combinations. Am i right?
So what is the matching speaker
for MA10wifi? is it DSL? But DSL is expensive. We want something
from Grundig range.
And i also get a
feeling that V1700 is your favourite integrated. So request you
to guide matching speaker from Grundig.
I am asking the above
for my friend who is also obsessed with your CCI.
Aktive 40 is my next buy. I am
saving money for it.
About “full CCI amps” there isn’t difference about “matching
speakers”…I haven’t a feeling about a specific Grundig amp, many
Grundig models are full CCI : all are very transparent and all
have a frequency response very independent to load (you can see
)…only a little difference is present between LT amps and
Grundig amps: on
Grundig amps you can’t be excluded the tones
(only Grundig preamplifiers have this possibility)...for
this reason frequency response on LT is more flat (a little bit
After long gap i am writting to
I was busy with my household
matters like school admission etc.
Yesterday for the first time i
heard PS-1020 with NOS n75 GT2 at 0.75 force.
Fortunately i was able to buy NOS N91G(grey),
N91GD(red) from ebay.
I also bought used N75GT2 here
locally. So now i have 3 spare cartridges.
Apart from above, i have bought
one cartridge made in mexico at ebay also.
Your remarks about this turntable
is spot on. The turntable sounds extremely good.
I have no words to express them. I
can not say they sound best in the world but certainly at this
price they sound best in the world.
I request you to post my email on
your "communication" section so the readers can get true
You had suggested me Xv-7500 and i
bought it. The experience was amazing. I am using it everyday.
Your suggestion ps-1020 is also
perfect. Extremely good.
Now i still have v7000 or v1700,
7500 tuner, Cd-7500 or 7550 and aktive 40 on my wishlist.
Unfortunately my financial
position is not that great. But once i am better off i wish to
buy Aktive 40.
This message is for expressing
sincere thanks to you.
I saw Aktive 40 at ebay germany item number 150618596510
Do you think i should bid?
Do you have
CD-7500 or v7000?
How you can read on my website:
I recommend mostly aktiv mod.LT to passive
solution (box850a/1500a/2500a) with amp LT (and
I say it versus my interest) while, conversely,
if you leave the aktiv "standard" (with no
CCImod.) I recommend mostly the passive series +
Grundig or LT amplifier (full CCI).
>Do you have CD-7500 or v7000?
Not for sell.
The only Grundig models that I have to sell are
PS1020 and XV7500 because I use them for
complete LT systems.
I am fully aware that CCI
is necessary for aktive 40. i was saying bidding and
sending it to you for CCI.
This particular pair of
aktive look in very good condition.
I will always listen to
you because my experience of Xv-7500 and ps-1020 was
I bought Grundig v1700,
it function with no problem, but I realized it was repaired sometime
in the past. There are changed components on one channel,
near output transistors.
Changed are resistors, small transistors and some caps. Amplifier
still works fine, there is no audio difference between channels. Is
it still CCI? Is it ruined in terms of CCI?
It’s difficult to say if it’s still CCI...repairs aren’t all good…
I also have V1850. It is in original state, no repairs and works
with no problems. What amplifier is your sugestion to use with my
speakers which are 650 Professional in room about
18m2? Also, I am unable to put 650 Pro. on bookshelf, they are on
stands made of MDF. Should I put them near to wall to get best
Yes, but for your room I advice Box850a or box1500a.
I use PC as sound source.
I made Atom based PC, totaly silent, without any fan,
connecetd to my DIY DAC (using output trafo's instead of opamps). I
put PC components in old Technics amplifier case, so it look as hifi
component. Is PC as source of signal is problem for Grundig CCI
setup? I am pleased with sound, but wonder
could I extract more performnce?
There is a great difference if source is not CCI…the better solution
that I have heard for pc source is the Apple Airport integrated in a
full CCI LT MA10 amplifier. However if you are curious of listen
difference between full CCI source and your, you can buy a Grundig
full CCI cd player on e-bay .
Thanks a lot and you have great site,
It's a long
time since our meeting. I still spend a lot of time with grundig,
but recently me and my friends have transfered our records
collections to hard drive and we tried to play them through
Foobar and laptop. Do you know any simple external DAC which
would work with CCI equipment corectly, or at least in the best
My cd's I
play with grundig but I have many of them from my friends -
that's wat can be played with external DAC. Maybe You did some
CCI modiffication to an comercially aviable DAC?
How to get
best sound from laptop and CCI grundig?
How are you?
The only solution full CCI that I purpose for lovers of “liquid
music” is the integration of MA10 with Apple Airport:
The solution with a DAC mod CCI is possible but the system is not
full CCI when you connect with wire a source no CCI to DAC CCI.
Cd players full CCI are still a bit better of Airport integrated on
MA10 but no so much.
I'm really OK!
I wonder if connecting airport to pre 7500 would also be
possible or it need special modiffication? How would work the
airport alone? Did you try it?
Do you have
any active box 40 with modiffication for sale?
Once again -
thanks a lot!!!
With Airport direct to xv7500 you obtain a partial CCI sound.
I have aktiv40 mod LT but are you sure that it’s the right box for
your room? Do you have a big room with listening point distant to
I think my
room will be ok, but I still think I wait for DSL:), just
thinking all the time. My seat is 1.5 m from rear wall.
room is ca. 30 square m.
Has LT 10
enough power to drive DSL? I have other quotations but what
would be cost of LT 10 with air port?
a big loss of quality with air port alone?
questions!!!? Thats all started with you:) Many thanks again!!
Say hello to your familly!!
Ok in this room aktiv40 is ok if you put its near to
rear speaker wall.
MA10 airport 50W /ch with phono have a cost of 2300eur.
Airport is switch off (must swich off…is present another
switch on rear panel of amp) when you listen others
inputs. MA10 haven’t problems with DSL. However if in a
later time you would past to solution XV7500+LT power
amp (MA50 or MA100) I value the retreat of MA10 at the
same price that you pay to me.
Airport integrated isn’t a big loss respect a full CCI
cd player (cd7500 or CD960 mod LT) but however is
present a loss…but at the moment I don’t know a better
solution of this for “liquid music”. It is also
important that the pc is supply to battery for best
Any preferece or information you
can share about 7550 and 7500?
Should i buy any of the two?
Cd 7500 is made with interconnect cable...this can be a preference
for choose this model.
Good evening Massimo,
Thank you for your response. I'm
sorry, I hadn't seen this page about cable. I've tried to find
the reference GBC mod. CA 201, but I can't find it on the web.
The only reference I find with CA 201 is from Real Cable ( http://www.real-cable.com/par-produits/audio/stereo-rca/ca-201-details-73.html
). Is it the reference you talk about, or is another reference?
Actually I can't find GBC cables on google...
The GBC cable have changed name...now have only a code :
Now i have following
things on my wish list
1. PS1020 with cover + M85G +
N75GT2 (original Shure NOS) checked CCI = 400eur
Please offer some discount.
What happens if N75GT2 breaks? do
you have spare? if yes, what is the Price?
Sorry but I can’t offer discount on this turntable...I think to
upper ( in a short time) price because the original stylus for
M85G ( the N91G or the equivalent N75GT2 ) are
very very rare
stylus. This is the only big problem of this top music enjoy
turntable…very rare find original stylus. I can supply only one
stylus for each turntable…for others stylus you can search on
2. V1700 Integrated
and Speaker 300
Per your last mail,
we should buy from ebay Germany and send to it you. This is ok.
Please advise your Shipping address. It it difficult to
ship to Italy? Any precaution/instruction i have to request the
seller? About declared value ? how mush should value should i
request? Any problem of Custom duty? How long does it take to
reach you from Germany?
Do you do CCI test on Speaker
model 300? if yes, how much is fees?
are no customs between countries of the European community, no
problems for shipping Germany to Italy.
I don’t advice V1700 to drive box300 for impedance problems:
frequently V1700 broken with box 300…
If you want box 300 I advice V7000, V20, V30, all large series
However box 300 have need a
very little room and put on a shelf….and experience
with Grundig products…it’not a easy speaker for starting…
My room is 20 * 25 Sq. Feet.(500
sq. Feet) I think it is big. maybe Model 40 Aktive would be
better option. Please advise your opinion.
Yes, Aktiv 40
One more simple
Why CCI for Aktive
Speaker is so expensive (500Euros) whereas amplifer v1700 is
speakers I execute a proprietary CCI modify because the standard
Aktiv are not full CCI,
on V1700 (or all others Grundig full CCI amplifiers) I execute
only a check/set-up for back to the
of them (these are standard full CCI)
Did Grundig made any
good cassette Deck?
Do you have any
interest in Grundigs Cassette Decks? Is CCI can be made
applicable to Cassete Deck too? if yes, How to get the Belts
and Pinch Rollers to this cassette Decks?
I am using Tandberg
3014A Deck. I love Cassette Decks too.
many cassette deck have the fantastic full CCI sound but also
have a big problem : alls grundig tape deck have problems with
How about Tuner?
T7500? I have Tandberg 3001A. It is one of the besti feel.
What is your opinion about T7500?
the best tuner that I know
Any CD player you would recommend
for CCI? Which is your favourite?
I have Sony CDP-R3. can i send it
to you for CCI? Please offer your opinion.
You have two way possibile for approch to CCI cd player:
buy on e-bay one of Grundig cd player full CCI
to execute a full CCI mod. in other commercial
The first solution is less expensive and if you not use the
remote control (Grundig cd players have not it) the only
problem is the affidability due to age of this cd
players…purchase must be a bit fortunate.
The second solution I can execute with many cd player, but
not on your cdp-r3, and have a cost of 500eur.
sent you an email few days ago about cable on a grundig system. I've
found a way to buy Vivanco hpfl 153, that you used to use for
yourself, as I red on your website. But is it possible to use it
both for speaker and interconnection? Is it also possible to use it
for both aktiv and passive speaker? What could I use if not for

My friend also liked the sound of
He wish to buy V1700 or V7000 CCI
Please advice if you have any unit
for my friend.
And what is the Price? Which one
is Good? V1700 or 7000?
The only Grundig apparatus that I have all the time is PS1020 and
XV7500 that complete the full CCI LT system. If your friend want a
V7000 or V1700 (or others full CCI grundig) He can buy on ebay
(search in Germany) , shipping to my address (from Germany) for
checking/ adjustment CCI and after I send to you. My work have a
cost of 70 eur + shipping.
I have started using XV-7500 and
my initial impression is that i like the sound. especially High
frequancy is excellent. But it is very early to comment. I have
listen only for 2 hours so far. I will tell my final opinion
after listening for about 50 hours.
You have mentioned everywhere that
Grundig should NOT be modified or Upgraded or refurbished. Can
you explain the reason.
Replacing the old capacitors is
also Modification? Should we replace the old capacitors or no?
If we replace the old capacitors, CCI benefit will go? sound
will be worse?
I do not want to
replace the capacitors now. But i am worried that this
preamplifier is very old, so someday these capacitors will start
leaking. So what will i do? can i replace or no?
And if you think we
can replace capacitors, then how can we buy the Old capacitors
made by Grundig? Can we replace by any other Brand? Do you
prefer any other Brand?
Thanks for your
you want mantain the full CCI sound
do not go to the XV with a
screwdriver in his hand !
If a capacitor has a problem there is a clear malfunction of
xv7500. When you have a malfunction you can ship to me the xv
and I repair in guaranteed (excluse shipping cost) with respect
for CCI . Please don’t change original capacitor or other
Is very important not tamper it if do not know the CCI rules…

Allowed me to send you a big thank you for your site.
When I was nostalgic looking for first device where I had learn to enjoy music: a Normend or Gruding radio with turntable on
top, I have find your site.
At first I had bought a Grundig PS-1010 turntable and find that is a very good turntable. And I know what I’m talking about. I
have several EMT turntables, Technics SP-10, Sony PS-X9, and others. So, I had bought Grundig V20 and XV 7500. When I hear it,
my eyes and my mouth open to the limit. My Pioneer TAD horn speakers are now playing with V20, and result is best sound I got
from this speakers. I had bough today V7500 and looking for Grundig speakers.
May I send V7500 to you to check it? If yes please inform address and price.
Could you please advice what Grundig speakers I should buy? My room is about 80 square meters.
Could you please inform too V7500, V1700, V20 and V30 characteristics. I have not find it anywhere.
A big Thank you
I can check your v7500 for a cost of 70euro+ shipping cost. For room very large of 80mq is indicated a

Please, read with attention these links:
On your web-site you wrote about GRUNDIG AKTIVE-BOX:
“The amplifiers can be upgraded to take advantage of "Linear Transfer technology".
Please send me any information about this upgrade.
PS. You know any possibility to buy original loudspeakers for Grundig Aktive-Boxes?
The upgrade (which I
execute only at my laboratory) makes full CCI the amplification of active speakers. The difference between before and after
you hear is about the same of comparing a V1000 (partially CCI) to a v7000 (full CCI): delicacy and air!
Thank you very much for your answer.
Please send me your short opinion about V7200 and V7150
Grundig amplifiers with reference to V7000.
and V7150 are only partial CCI...
Thank You very much for having me in your house.
This was very nice visit.
You have wonderful family! My children are very proud that they have Italian friends!
I enjoyed this meeting enormously .
I was also very happy to know
You and your beautiful family, sorry for my very poor speak english...
Your main system is amazing, but grundig was more than impressive as well.
I connected every component in my system correctly
with attention to cables and it is definitely better now. As I sad before I don’t have special room for listening so I’m
afraid the level of CCI clarity is far from perfect (other equipment in the room) but better than it was before.
I was shocked by difference in clarity, space and beautiful imaging of both your systems when proper CCI is implemented!
In the future I want your main system J.
I will send you my amp and preamp and cables for checking the CCI before making the final decision of course.
We drove home for 18 hours but believe me it was worth it. It was the best musical experience I had and best part of my
It helped me with my system very much.
I have the same tonal character now. The only problem is uneven scene. But I hope I can fix this. The cable I use to connect
preamp and amp is not perfect. Grundig plug on the din side, but different cinch plugs. I will work on that.
Did you use grundig cable din to din with thick metal plugs? Is it good?
Once again many thanks!
I will post a letter of my feelings and thanks on the forum, once I have a time to write it. Ciao!!! Pawel.
Thank You Pawel for your nice
All Grundig cables are the
better cables (it's incredible but true...)

I am intersted in Grundig xv7500, 1020 and LT amplifers.
I live in BAngkok Thailand pin code 10110.
Sorry for my late reply but I returned today from a week's holiday.
Yes, I can supply ps1020,xv7500 and LT amplifier
Price of them are the follows:
-PS1020 with cover + M85G + N75GT2 (original Shure NOS) checked CCI = 400eur
-XV7500 checked CCI = 500eur
-LT MA25 : power amp full CCI 25+25W/8ohm = 1800eur
-LT MA50 : power amp full CCI 50+50W/8ohm = 2500eur
-LT MA100 : power amp full CCI 100+100W/8ohm = 3500eur
Shipping cost to Thailand is (obviously) dependent to weight.
I need help about turntable Grundig PS1020.
I purchase on ebay.de turntable PS1020, and I received it with original cartridge Shure M85G and with 2 broken styluses which
are not original N91G.
Can you help me about this problem?
First, I looked for original stylus on the internet, and I find many replacements.
And I am confused. I don't know what is original stylus and how it looks like.
Also, I don't know is this cartridge M85G (on PS1020) OK, because I can not try it without stylus.
I read on your internet site
that the best Shure cartridges and stylus are: M75B with N75Gt2 and M85G with N91G or N75Gt2.
One friend of mine, have Shure M75MGD cartridge, and it was with yellow stylus, and many years ago, he buy in Germany other
On that box of stylus was written that this stylus is for M85 cartridge, and after that he did not use that cartridge.
He offered me that cartridge Shure M75MGD with dark gray stylus. On that gray stylus is written only "SHURE".
Is it M75MGD a good Shure cartridge?
Do you know, what is the model of that stylus? Is it maybe N75Gt2?
I find many types of Shure M75 cartridges on internet (M75MGD, M75MBt2, M75MGt2, M75EDt2, M75Bt2, M75-6, M75E, M75Et2, ...).
What are the differences between them? Which are good and which are not?
If you know where can I read about Shure cartridges and styluses on internet, please tell me.
I try on Shure site, but I didn't find information.
Also, I check "letters" and "forum", and I don't find answers there.
And if You have some pictures of
Shure cartridges and stylus, please send me on e-mail.
must find only the stylus for M85G (the better cartridge for ps1020) and you can choose between N91G and N75Gt2...both very
rare to find in internet...
have a little stock of original Shure NOS (new old stock) N75Gt2 but I sell one N75Gt2 to 200eur...

They are both full CCI, cd35x = 16bit, cd35 = 14bit.
However I prefer the cd35...the cd 35x is a little bit closed on high frequency (like you can see in frequency response:
I got a box300 and R45 recently, they sound wonderful with your DVD LT-mod.
Do you have speaker cables for box300? the speaker cables of box300 has been cutted, and the connector of R45 is as
same as V7000.
By the way, I will have a business trip to UK on May 7th, please let me know if you can send the cable to me.
I haven't original Grundig cables, but you can find on market one cable with similar copper diameter and with rigid
sheath (not siliconic sheath) for reach similar results.
i read about the cd960 LT mod on you website.... i have a cd960 too, and iam interessting in this mod
can you give me more informations? ... please
i think about a zero oversampling mod! ... is this the same?
greetings from austria
the LT mod of the Philips CD960 (but I can modify several CD players in
the same way) is not related to zero oversampling or any other
electronic mods (like caps replacement, op-amps replacement, oscillator
replacement...). The LT mod is a very accurate tuning of the chassis in
order to reduce any audible HF interference during the sound
reproduction. The improvement is really big in a full CCI hifi system
(LT/Grundig). The cost of the LT mod is Eur 500 excluding shipping
expenses from/back to your address.
thank you for your answer
its very expensive..... but interessting.....
i will test for the first... the non oversampling, its easy to do.....
The zero oversampling is very different sound of CCI sound, I don't advice zero
oversampling if you love the music feeling.
hello & good morning
i think about that converter
its cheap and i can build it back to the original every time
do you know the converter??
The first italian DIY that have executed zero oversampling mod. is Marco Amboldi (some years ago)
http://xoomer.virgilio.it/hi_fi/com.htm , today he have a cd960 with normal four oversampling but
mod. full CCI...
For info: firstname.lastname@example.org
thanks for the link, i have seen this site..... the full CCI is also interesting, but i dont want spend so much money in a cd
player.... my speakers or amp not cost so much.... all vintage hifi .... speakers JBL 4311 ... AMP Sansui AU919
i only interesstet in simple and cheap modification on cd players,.... i want do find out whats possible whit less money :-)
.... i have a second philips a CD304 ....
i will look for a SONY CDP101 ... the first player.... this player have no oversampling.... i want do hear this, i have read
so many.... so iam curious :-))
do you have any player you want sell do me?? .... iam also interessted in a player whit tube´s in output.... like lampizator
greetings from austria
I advice to you the only CCI models made in Grundig : cd7500, cd7550, cd35.
You can find on ebay.de.
Quality sound is very better to other normal cd players but these are without remote control
i think the cd7550 is the same like my philips cd304??
CCI .... can you tell me more about this??
I stumbbled across your website and was wondering if you could help me out with some information. I have found a couple of
Grundig Super Hi Fi 850a Professional and before i buy them I wanted to know if I can use them as normal speakers with my Flat
Screen TV? I am not an expert at all when
the Grundig Super Hi Fi 850a are really serious hifi reproducers and
they need the best LT/Grundig electronics and an accurate placement.
So, I do not suggest to use them as normal speakers with your Flat
Would DSL speakers play good with grundig amps?
Yes, this is possible if you haven't a large
My question is: would it be smart to buy speakers only at the
beginning and then move to M50?
hope I can join one of the meetings next year! Pawel.
would be the cost of DSL speakers?
DSL cost is 3800 eur (inclusive wood package
for international shipping)
I want to ask your advise.
If I'm using Box400 on stand (no other choice), a metal stand for Linn Kan, what distance from front wall should I place them?
Room length 4.8m, wide 2.85m. I have V7000, V20 and V1700. In your opinion, which one result the best?
Box400 are not for stand installation but only for bookshelf installation.
If you want test a two way Grundig to stand you can find box450 (or box550) first series (not professinal).
Differences between CCI Grundig amplifier are dependent more to condition of every one.
Why do you say Box850a, Box1500a, Box800, Box1000 are stand-mounted speakers? I have Box850a, but I use them as floor-standing,
for I don't have stands. Is there a big sound difference between stand-mounted and floor-standing Box850a? Should I make
stands for them and how? Can you give me more details please... Amplifier I use is V7000. Thank you.
any loudpeakers needs a right placement in order to linearize its
frequency response. The woofer reflection affects the frequency
response in the bass range and it is related to the distance from the
walls and from the floor. This is the reason why the Box850 really
needs 36cm height stands. In this case the speakers must be placed
80cm far from the front wall and the listening point (your head) must
be located 40cm far from the rear wall. The stands can be built using
tubular metal frame (square section); please check it is very plane
and stable on the floor.
I am Ante (Antonio) from Croatia.
I have Grunding speakers "super Hi-Fi
box 650" and i have found them very realistic even that 2 hi and 1 mid units are broken. I put some other units instead,
just for a "first aid".
After i have "worm up" for grundig, i
found your site. Can you please recommend me what to do with that units - if i can't find originals, is there somethig
else that i can put instead?
I found hi-fi dome tweeters (60w, 8ohm)
from monacor catalogue - are they good enough?
I have opportunity to buy receiver
Grundig R35 - can you please tell me is it good / is it in high grundig class?
the receiver R35 is really high class but, before buy, please check
it is in good conditions. There is no replacement for original
tweeter/midrange Grundig units in the market. You have to look at
ebay or second hand market, I'm sorry.
I am very big fan of you and your site! I red all your tests and experiences about Grundig and I am speechless. I also
have some of your favorite components like V7000 amplifier, CD7550 cd-player and T7500 tuner. And 2 weeks ago I also
received Box 850a speakers, but unfortunately without DIN cables. I was looking on e-bay and several stores in Vienna but
I couldn't find those cables. You already helped me a lot with your advices about Grundig products, but I must ask you one
more time for help. Please can you tell me where should I look for DIN cables for Grundig Box 850a speakers or can you
provide (sell) me those?
don’t know where you could find DIN speakers cables in Vienna but I think possible buy DIN female connectors and make its in
home with SCHWAIGER or equivalent speakers cable.
>The updated amplifier arrived today. I have connected it and played
some music. The first impression is that the music has much more details than before. The sound is more full bodied, more
dynamic, has more sense of space, sweeter high and mid and more powerful bass.
Anyway, I feel the whole picture of the music is much more transparent than before, a whole new experience. It is a big
improvement indeed. I would like to thank you very much for this gift again. I will play more different music and let you know
more of my feeling later.
I am happy :-)

My name is Bora and I live in Serbia. I am very interested to buy Grundig amplifier V7000 and as I reading letter
from your site I have get impression that you can help me. I can't find that amplifier here in Serbia, so, I am asking
you for information how and where can I buy it.
Thank you in advance!
You can find v7000 on ebay.de I can sell one of mine v7000 (checked for CCI implementation) but is over ebay price.
I have been through your
site number of times, just to understand how deep you were involved in doing research with all these audio components.
Actually I do similiar to something what you are doing, but difference could be the price of stuff you deal with (you amps and
preamps looks much more expensive).....anyway. With your advice (in the website) I just brought V30 (ofcourse grundig) to try.
I was amazed......the quality of sound it was producing was never heard before.I compared it with all my previous ones, luxman,
yamaha, sony, marantz even Nad, nothing could stand against it. I am planning to buy SXV7500 and V1700. The only problem I
face now is I REALLY NEED a remote control with volume, which these great devices do not have. do you have any suggestion to (somehow)
get the same You never discussed V1 or V2 or R1 or R2 ......or FineArts by Grundig. Are they good as well?? Looking forward to
hear from you!!! Regards Bandeep Singh Neuenhof Switzerland
Dear Sir For remote control on CCI system you can find one RPC600 or RPC650 .
Fine Arts is not good (not CCI)
Hello. I'm Kim. I Live in Nancy, France.
First of all, I'm appreciate to your site. It's very useful for me.
I'll buy grundig amp, cdp. speaker, but my room(residence of university) is so small. about 3.5 x 3m.
But so many grundig choice. I don't know what I exatly select suitable for my room
There are Grundig Amp V7000(100euro), V35(about 80euro), V20(100euro) and Speaker BOX 350(about 80euro - It's auction),
And I'll buy cd7550 and T7200, so What do my best choice if I buy only one amp + speaker?
Another question is There are huge different between T7200 and T7500? cuz, T7500 price is about 100-110euro but, T7200 is
about 30euro. And in Ebay Germany, there is some broken cd7550. If I'll buy this one, could you fix it? I know it's very
rude, impolite question. But CD7550 or 7500 is so rare item, and some higher price. Maybe It is some more cheaper than buy
normal cd 7550.
Last question, Sir you mentioned about some fault about V7000, 35. If I'll buy one of these amp, If you could fix it some
detailed falut? And How much including shippment.
Thanks for your attention.
could you please advice me about the Linear-Transfer-technology upgrade
for a Grundig 50 active box? Is there a buy-it board or any instrtuction/drawings online?
Thanks in advance -

if your local Grundig service is going to service your CD7550 please be sure that disassembling and re-assembling will be done
and carefully at the same way. I usually check
only the V7000 amplifier for full CCI implementation but I do not service any Grundig components.
A full CCI system can sound more natural and rich in
harmonics comparing to the other hifi systems. If you need, I can supply cables to you.

If you listen them there are not a little differences with Philips/Marantz clone...
So out of all the turntables
you have audiotioned which ones did you prefer?
My prefer turntables are Grundig Ps1020 and Ps1010.
That’s incredible...I know.
Thank you for good insight and guidance about audio
I am amateur engineeer , programmer .
First hear about you from kwangbok lee by way of Grundig audio.
After hearing that I bought some grundif and listening with them , some
amps half diamantled .
know what is "problem", But Really Interesting to think such things.
So I cannot but to express many thanks for such "koan" (koan is zen word)
And hoping your happy and intersting days.

My prefer turntables are Grundig Ps1020 and Ps1010.
That’s incredible...I know.
I was reading your letters
whole night and I read very useful information about Grundig products. I am not an audio profi or something like that; I
just have friend who collects Grundig amplifiers, tuners, cd-players, speakers… and he told me about your site. I really
share opinion with my friend that Grundig is on the top, because I heard few songs from his system and it was really
amazing! Last night I purchased two tuners T7500, as you said that Grundig T7500 is best Grundig tuner. I started with
tuner and I am going to buy amplifier V7000 (or should I go with V1700?), CD7550 (or CD7500?) and of course 850a profess
passive speakers. I would also like to have turntable but I didn’t see much discussions about them. I would like you to
recommend me few model which fits, or which would fit, components I am going to buy. And I would like to ask you one last
question. Can you supply me with some missing components since it is very hard to find them, especially turntable (of
course I would pay)?
-turntable PS1010/1020 complete with cover
and original cartridge, checked for CCI conditions and with original NOS (new old stock) Shure stylus N75Gt2 (very very
rare to find)
-V7000 checked for CCI condition
No cd player at the moment.
I am going
to ask you one more question, for I am waiting on your answer. Is it really necessary to have preamplifier for Grundig
PS 1020 turntable, and if yes what do you think about SXV6000? Or can you recommend me few other preamplifiers? I know
what you said about
XV7500 but it is
very hard to find one… almost impossible, I would say… But I would rather connect PS1020 directly to V7000 or V1700
than using preamplifier which can “ruin” beautiful sound; do you agree with that option?
SXV6000 have the same schematic circuit of XV7500 but not the same CCI evolution. I don’t advice sxv6000.
can supply XV7500 checked CCI.
Only full CCI preamplifier alternative is the preceiver X55.
XV7500 it’s however not necessary and you can have a very beautiful sound with v1700 / v7000 / others CCI amps.
Thank you for good insight and guidance about audio
I am amateur engineeer , programmer .
First hear about you from kwangbok lee by way of Grundig audio.
After hearing that I
bought some grundif and listening with them
, some amps half diamantled .
I dont know what is "problem", But Really
Interesting to think such things.
So I cannot but to express many thanks for such "koan"
(koan is zen word)
And hoping your happy and intersting days.

Hi, I am a fan of Hi Fi systems from
Iran. I got to know your home page because I was looking for informations about Grundig
Box2500a. I have bought a pair of this speakers last
week. They are second hands and I don´t know any thing about them. You say in your home page that this speakesr have a
built in amplifiers. I just cheked out mine and unfortunatly there´s just two capacitors incorporated. Would you mind
giving me more information about this built in amplifier. Im very upset, altought the speakers sounds grate as it is
thanks for your e-mail. As you can see in my website, the speakers that have built-in amplifiers they are called "Aktiv
Box". The "Aktiv Box" series is composed by various models: 20, 30, 40 and 50.
Please, check my webpage:
passive series looks very similar to the "Aktiv" series. But the passive series (models 850, 1500, 2500) does not have any
Anyway, the 2500a is a top-class speaker. You should drive the 2500a using a V7000 or V1700 amplifier. The best CD source to
complete the system is the CD7500 – CD7550.
I'm very happy to find your website and your
achievments! Especially Grundig story.
Lately I;ve bought some old Grundig products:
1. GRUNDIG HIFI BOX 306 COMPACT and

What is your advice? Did you listen them? Will they
play good together?
Which loudspeakres are better 503 or 306?
thank you for your advice !
for your kind message. I think you will enjoy your Grundig components even if they are not the best. Box 306 are better than
503 but the best are the Box 300, 400, 500, 850a, 1500a,2500a. The best amplifier are V7000 V1700, V20, V30 and large
Receiver series. You have to find a Grundig CD7500/CD7550 to complete your system.

Your speakers (of box300 and of box650) are in perfect standard condition, no defect.
On rubber of box 300 is a standard anti-humidity treatment and PLEASE DON'T TOUCH IT !!
Check only if your boxes have a good air sealed: push (very gently) on center of woofer, when you release, it must return very
slowly to normal position if no air loss.
if it's ok , insert the grilles and install box 300 very near to wall and ON BOOKSHELF (no more height of 60cm) or supported
on a pair of box2500 (used like stands).
Box 300 needs a very little room for a good performance in bass frequency. Also your listening point must be no more distanced
to 40cm to rear wall.

I am sorry but box330a have a

After completing two whole CCI systems my conquest for perfect sound stopped abruptlyJ . Seriously speaking I had the best
time in my life in terms of musical experience (since the turntable came last year). I never had really chance to say THANK
I was in Livigno this winter but had no time to travel any further. But one day I will visit you in person and will get some
of your amps and speakers. I was moving around a lot with the speakers (the 850 upstairs sounded too different than 1500 in
the other room) but finally I found the “SPOT”. They were just tilted forward too much, after changing that - no more
differences (just the right ones!) perfect space and vocal and highs etc.....
One more business question – would it be possible to get modified DVD from you, we can agree which model, but this way I will
spare the shipping cost from Poland to Italy/ let me know if this can be arranged.
To make the long story short thank you again. I may one day put some more thoughts about my experience on the forum but it
seems to me the forum slowed down a little recently.
I hope I can be in touch with you guys. Regards! Ciao! Pawel.
How are you?

The CCI mod on DVD player have a cost of xxx eur and shipping cost for Poland with air mail is about of 50 eur.
I offer ever inclusive in this cost a singolar opportunity: in case of serious breakdown (laser) I move free of charge the
modification CCI on other dvd player for one time.

You can increase to 1gr or 1,25gr for better tracking but with a worse of sound
PS1020 is 1020b. Is it different from PS1020a? PS1020a that my friend

My request is the following to you:
I bought a Philips CD 960 player few days ago ( looks like a new one) and I am very impressed by the nearly analogic sound. So

but I do not know how to start with the modification. I am a little affraid, If I modified it I am going to loose the nice
I would like to ask you if possible to send me some inside photos and detailed description about your famous linear transfer
modification. I would be really thankful if you could help me.
Thanks in advance again.
Sorry but the LT CCI mod. is a proprietary implementation and I execute only in my laboratory.
The cd960 standard is far to analogic sound, if you want listen a CCI cd player with small cost you can buy on ebay.de a cd
7550 or cd7500 Grundig....You can listen which is the mean of “analogic sound”.

Greeting from Romania,
sorry to disturb you,but i have a few question.
I own a pair of Grundig box M600,wich i have tryed to drive them with a Rotel 840 bx 4(doesn't sound so good, missing the low
freqvencies),the best that drive them is an old Korting A100.I was studiing youre site and i have the folowing question:
1.The amplituner Grundig RV 5000(or R5000) will drive them better?(i'm asking this because i don't have the chance to listen,only
to buy from the internet).
2. In this moment the pair of Grundig are mounted on stand and they are 1m away from the back wall and 30 cm from the side
wall,and there is no chance to put them in to a bookshelf as you sugested.The option would be mounting them on the wall(they
have some holes left for this purpose,i belive).Do you thing it is a good ideea?
1. The best Grundig amplituners are the R20, R30 or the old Receivers 20, 30, 25, 35. But you can also look for R1000 and
R2000. The high powered models like the R5000 are a bit worse.
2. Do not mount the M600 on the wall. Try to lower them near the floor if needed.
Thank you for you're response.
I've taken you're advice and i bought the closest thing that you sugested and that's Grundig R3000 (that's the best i could
find in Romania) and you were 100% right,the sound is amazing.The recever is not in the best shape but it's ok,i need to
change some capacitors and some of the light in the front panel but the rest is all original and untoched(a lot of dust in
it).Now i thinking of taking you're advice a litlle more and buy a cd player from Grundig 7500 or 7550.
>Hello Massimo, could you tell me what are the differences between 1rst

differences between 1rst and 2nd edition? I know the one with black cone on the

There are exactly three version of B&W DM6 The first with woofer control level, wood front panel and all yellow midrange.
without control level on woofer , plastic front panel and all yellow midrange.
Third series without control level on woofer , plastic front panel and only cone yellow midrange.
The best is the second series,
the worse is the last series.
>You say that the Dahlquist DQ-10 are
equal to the B&W DM6(1st edition)
Not equal but similar quality with
>and plenty people at "audioreview.com" said
that the DQ-10 are a little "light" on "base >department" but my
experience with the B&W DM6 was different, the "base" is fantastic
(they >were placed near the back wall)... i am confuse now...
intend the "bass department" the DQ10 is not "light" if placed on their
standard 3 little foot (about 12-13cm height). DQ10 become light if is
placed on stand of 30cm (or more).....
Hello, i am french (near Paris) and i am sorry for my bad english... but i will tried to make my best...
I was looking information on internet about the B&W DM6 and i found your website with the list of recommended products where
was the B&W DM6... I know this speakers because a friend of mine have them in London, and each time i am visiting himself i
was amazed at how good this speakers sound... even compaire to my speakers that are JBL 4311, Acoustic Energy 109 and Klipch
The DM6 seamed to sound just perfect to my ears!! Beatifull base, marvellus mids, airy, transparent and full!! (his amplifier
is an HK PM635i / 2X40W)
I am writting to you because you experienced this speakers and the Dahlquist DQ-10, JBL 4311, Quad ESL 63, Magneplanar... Four
speakers that i am very interested for having especialy the B&W DM6.
Do you have any recomendation? do you prefer the Dahlquist DQ-10? you said about them that they are one of
the best multi-way floor standing speaker... are they beter than the B&W DM6? do you know a better multi-way speaker that is
not on this list (in a moderate price 500€ =>2000€)
Sorry for all this questions, but before buying the B&W DM6 i wanted to make sure not doing any mistake!
I thank you in advance, and hope yould help me...
Have a good day!
The B&W DM6 first series (with midrange all yellow) is a great speaker at the same level of DQ10.
Better of this I know only the Grundig professional series loudpeakers (box2500a,box1500a,box850a), You can read my website...
Hello Massimo and thank you very much for
I feal more confortable about the B&W DM6, also, i never though that this GRUNDING speakers were that good... i will take a
look on them.
Ehm "Grundig" and not "Grunding"....
Two last questions:
1/ I was VERY impressed about DM6 "base", (quick, low and clean) is the Dahlquist DQ-10 as good?
Yes, very similar quality.
2/ I alwas wanted to have some JBL 4333 or JBL 4343... what kind of sound it is compare to B&W DM6 and GRUNDING
Bass reflex supply a different kind of sound in middle-bass frequency : more empty
Thank you so much for helping me...
Have a good day!
PS: I have good fun reading your website yesterday night, you seam to wanted to reach one goal => musicality, what ever the
price, the brand or the technology and i like that, nothing esotoric, just musicality...

The solution MA50+xv7500 or integrated MA10 have the advantage of more linearity due to absence of tone

The difference between CCI cd player and CCI turntable is very dependent to type of recording: a digital master is more
probability better on cd player, an analog master is more probability better on turntable.
If your cd7550 is in good conditions there is only a little difference with cd960LT. However the cd960 has a remote control
while the cd7550 not....

1) T30 is a very good full CCI tuner.
2) T9000 is not a CCI tuner (sound is not so good). The Grundig best tuner is the T7500
3) The cover (grill) of box350 (first type) is maintained with stucco: you must make lever in an angle with a little
screwdriver in order to detach the grill from the stucco.

I know the old box 80 , good boxes with old hot sound and cone tweeters but if you like the better trasparent sound I advice
more the Grundig products presents on my website.
However the trasparent sound box need of trasparent sistem CCI : box more trasparent evidence more defects to mount.
I'm from stoke. I
got speaker Grundig Box M800 from my friend. The problem is this speaker need special cable or port. How can I get it?

Hello Joe (it's correct your name?)
I am happy that you and your wife
like the CCI sound!
For your problem can you send my an internal photo of your v35?
To follow I can help you
I'm so glad you respond my question..
My correct name is Jioe.
Yes, we both very please with the CCI sound result. I bet your LT amp doing better!
In this note, I attached some photos of my 2nd V35. The first one using siemen was borrowed, so I can't take the photo yet.
I hope the files are not too large. In the photo, you can see ROE 10000mfd is some kind of rusty.. Is it risky? One of 4 power
transistor had different look. Is it no problem also?
I have Philips 303 also. Some information on internet says that it definitely the same like CD7500. Is it true? But
unfortunately, it generate some noise, just like a cellphone interference. It happens just for few minuttes when device turn
Thanks for your concern..
worry, your v35 is in good condition!
cd7500 is a full CCI cd player, the Philips 303 not.

Yes, there are some difference on cabinet and CCI implementation and the sound is a little bit worse of v20.

Yes, but not the "high" series (cf7500
for example is very worse of cf 7100-7200....)

I am happy you appreciate my suggestions. I hope you'll complete your
Grundig system soon and let me know your comments.
I had some mail exchange with Greagaudio but I do not know him and there
isn't any direct relationship between his work and mine.
I advice to NOT MODIFY all Grundig CCI products.....
Modern hifi producers spend a lot of money for marketing and design; a
lot less money for research. In fact, some "classic" products (BBC
LS3/5a, ESL63, Dahlquist DQ10, Leak amplifiers) sound far better than
modern products, as you can listen in direct comparisons.
Grundig of 70/80ies is another story due to some very advanced technical

On auction are a pair of box350 first series (the better box350).
This is a very good box for bookshelf installation (not for stand!).
Only a little bit worse of box 300.
Yesterday I purchased Grundig CD7550. It is in very good
condition. And it have a very very good sound.
Now, CD7550 is in sistem with Audio Innovations S500 amp and
Grundig Box FL-10 speakers.
Also I have Denon DCD-2560 and I am starting to compare the
sound of these two cd players.
First impresions are that CD7550 sounds more lifelike
(vocals, percussions, guitars, piano etc )...
I can not find GBC CA-201 cable, what is your recomendation
for interconect cable?
Here, I can purchase Hama, Oehlbach...
Also here, on the secondhand market, I can purchase receiver
R7200 or amp V7150 (T7150, CF7150) now.
I am waiting for V1700, V7000, V20 or V30 amps, but until
that time, I want to try complete Grundig sistem.
What is your recomendation R7200 or V7150?
I am happy you have found a CD7550 in very good conditions.

If you buy a pair of box850a

you don't reconnect the B&W... :-)
>I also want to ask if you are

Of Grundig productions I can supply only the

I can supply also interconnected cables enough equivalent to Grundig
On turntables the cable is standard included .
>There is one more thing. There is Box 1000

Thank You! Pawel.
box1500a (and box850a) are better of box1000.
Can you tell me something about
Grundig components V7150, T7150, CF7150, PS1700 and RB640 or
where can I find something about them?
As I know from your experience,
best are CCI components (V7000… ), but how good are these
I think that models 7150 are from
1985 – 1986?
started collecting grundig equipment!
Is the R
30 amplituner similliar to V 30 amp? Would it sound close to the
amp. I have box 660 speakers? please let me know, I see big
potential in those speakers with my "conventional "
amplification. Best Regards. Pawel.
The R30 with the same aesthetic of V30 is with loudness not
switchable. I don’t advice it.
Box660 is a good Grundig box of year 84 with a big potential but
it’s not the better series of Grundig speakers (see my website)
My friend have a Grundig High Fidelity Box FL-10. And he
want to sell it. He borrow that speakers to me.
Now, I listen a Grundig FL-10 on Audio Innovations S500 tube
integ. amp. and Denon DCD-2560 cd player.
Sound is very very good, only bass is not so strong!
The bass is dependent to room size and collocation....
In a small room and with listening point near to rear wall you
have a good bass with FL10.
What do you think about that model, do you know something
about Box FL-10, did you listen it?
only know that Grundig FL-10 is 3-way 4 ohm speaker, with power
rating 50W nominal, 75W music (that is writen on the back of the
What do you think what is fairly price for FL-10? How much did
they cost when they were new?
They are in great condition, looks and sounds like new!
You can buy a pair of FL10 on ebay.de to 100-150 eur.
It’s not the better Grundig but it’s a very good Grundig box!
think in these days factories do not make that kind of speakers.
Now, everything is in design and marketing, but there is not
music! And I did not hear that kind of sound in price range of
1000 euro and more (for pair of speakers).
Also more more over 1000 euro... :-)
If you want improve your system you can change also amplifier
and cd player with Grundig CCI (see my website).
I read your
recommended list of components, and am kinda confused as to why
you recommend two things-
first edition. What do you mean? The non-mirror imaged ones, or
the really early ones with the 7.5 woofers-which incidently
almost nobody has heard of. I have 3 pairs of DQ10's-two sets
came with non-mirror imaging, and I reworked them to make that
happen. The 3rd pair was factory mirrored. I liked the sound of
the non-mirrored ones, but liked it better(yeah, what does that
mean in audio language-better separation?) mirrored.
-the small 3
peg legs. You know, I gotta agree with you there. I have home
built (I think the nice word is "custom" built) cherry stands
that raise them 14", and I like the sound better with the little
legs. Maybe more punch; the correct angle; bass notes from the
woof getting a head start over the higher notes, so that they
hit the ear at the same time-whatever.
Hope to hear
from you about the "early edition" question.
I mean the non-mirror imaged DQ10. The non-mirrored configuration is
acoustically better than the mirrored.
This weekend I bought two grundig SL1000 Brown
collored towers for 40 euro's. I'd like to know what i purchased caus e i
absolutely have no clue. I just liked the looks of it very much. I read
some comment you gave to Kwang about these boxes. I haven't heard the
sound of it jet cause the connection points are not suitable for my
stereo. There is only a powerpoint which looks like this _. but then above
each other. While i normally use tullips? As you understand now I 'm an
absolute no no on this subject, what's the best way to connect them to my
congratulations on your purchase. The SL1000 are very fine speakers
and they should be matched with others Grundig components.
To connect the speakers to your amplifier, you have to buy a couple
of 2 pin DIN plugs and terminate your cables.
What is the
modification you do on a Quad esl 63?
I am sorry but the LT CCI modification is a proprietary technology. It is
exclusively applied in my laboratory.
> Dear Massimo,
>The last question....could you compare "xv7500 + aktiv20 LT-Mod" with

>I am very sorry for bothering several times.
Aktiv20 LT mod. are very similar to box850a + MA50 (or MA10) but are very
differents to SL1000
speakers! The SL1000 is a 2 way that needed a small room (not more of 15mq)
for supplies a good result to low frequency and much care to installation.
Moreover is needed a listen point near to rear wall
(wall-ear distance about 40cm). In this conditons the SL1000 supplies a
sound more free of 3 way speakers and it maintains the middle frequency of 3
I read your website from time to time and I enjoy it each time.
I do not own
any of your specially recommended equipment but are interested if you had
the opportunity to listen to a Grundig device I do own personally and which
does not appear on your site: It is the Grundig Preceiver X55a (in
combination with 2 pairs of Aktiv Box 30 and 40), a device from 1979 and
back then constructed for combination with Aktiv Box 20/30/40 or 50. Though
not especially “neutral” I think the sound is very enjoyable and conveys a
lot of musicality.
As the X55a
is a class A device I think it was the basis for the construction of the
later XV7500 (and SXV6000). Did you listen to X55a and Aktivbox 40
combination and have an opinion on it compared to later Grundig equipment
recommended by you (XV7500)?
Yes, I have listened to the x55a with great satisfaction and it’s a full CCI
apparatus as xv7500.
The differences between x55a and xv7500 are due to presence of tuner on x55a
and to tones control excludible on xv7500.
Tones control excludible is an advantage for xv7500, the tuner (on x55a)
causes an impression of more harmonic sound but it’s only due to more
insensibility to not correct installation CCI.
See link “installation” on my website.
With aktiv box standard (not CCI updated) the x55a supplies a great result
but less deep and less delicate than the combination xv7500 + aktiv box LT
>I am thinking my next step...
>Please give me a suggestion of following ...

The two solutions could get the same performance if you can place the MA10
between the boxes (for reduce the length of power cables) and place on rigid
surface the xv7500.
The solution MA10 without phono has a disadvantage: does not allow you to
use the turntable... :-)

The CCI implementation is the same of Grundig V1700 (optimized for soft
surface).The sound differences are due to tone controls not deactivable on
Grundig integrated .
MA10 supplies a little more deep image and little more "thickness" of
sorry to disturb you again.My name is Ritchie(cinderella is my nickname
to cause your obession).
The other day.I found the Grundig XV5000 and A5000.At your Gundig Story I
can`t find any information about XV5000 and
A5000(I can`t read the Germany,I
live in Asia).Also, I need your any suggestions and your commends again.My
speaker is box450.Thanks a lot.
thanks for your e-mail. The 5000 series is not so good as the best
Grundig (full CCI) amplifiers (V7000, V1700, V20, V30, V35).
Last week I followed your
instruction to place cd94mod LT+ v7000 + 850a, and I got fantastic result! I
am thinking my xv7500. I don't think that I could have enough money to buy
MA50 or DSL speakers. I am wondering whether the xv7500 + Aktiv 30 LT-mod is
better than v7000+850a or not?
if you want
to compare active speakers to the passive, you should compare the Aktiv 20
to the 850a and Aktiv 30 to the 1500a as they have the same woofer size.
to the Aktiv series with LT modification, the result is a bit more dynamic
and the definition higher. But the sonic result is really similar. The Aktiv
series must be used on stand (36cm height) and well placed on 4 points.
My friend test the cushion. He put them on the bottom of the speakers, but
got bad sound. Could you describle more in details for me?
By the way, there is a set of Grundig equipnment for sell...V35+CD35+T35.
Are them with full CCI?

Sorry to disturb you, I have the opportunity to own a Grundig Super Hifi Box
But i can`t find any information on the internet.Could you tell some
information for me? And your commends. Thanks a lot.
Dear Cinderella (what a strange name...),
Grundig Super Hifi Box 450 is a very good choice, just a bit worse
than the brother Box 400. There are two different version of the Box
450: the standard and the Professional. Both are good.
I suggest obviously to complete the system with a Grundig/LT CCI amplifier
I have Philips CD 960 and I am interested what kind of mods you are done
and what is
LINEAR TRANSFER modification. If you have any list of possible
modifications or(and) web address where I can see I'll be really grateful.
I am sorry but the LT modification is a proprietary technology. It is
exclusively applied in my laboratory and the price is XXX eur
Sorry for the late reply as I just came back from a seminar conference
I have found the DSL sounding smoother and more coherent with longer
break-in period. The cushion experiment really improves the solidity of
the whole sound landscape. Image staging becomes somehow more precise
with improved tunefulness (listening with feeling). Now I wonder how
you could come up with such an ingenious idea of the cushion treatment
When you are not too busy, please tell me some other nice recordings to
enjoy LT System even more. The obvious sensation of having a complete
Grundig/LT system around happens to be the irresistible factor that we
want to listen to music most of the time. It's becoming harder to
switch off the system, is this also happening to other LT members???
The idea of the cushion treatment is related to the reflexions of the
internal side of loudspeaker cabinet. These cause irregularities (peaks and
dips are reinforced) in the frequency
response. The 1/3 distance of the cushion improves linearity. In fact, the
distance of the reflection is now different for both sides and peak and dips
are far less severe.
The cushion works well with symmetrical speakers (like DSL) but does not
apply to asymmetrical speakers (like
3way grundig speakers: mid and tweeter are not specular) as they already
distances in emission centers.
Recently I have found the Grundig Box 550 B speakers on the Internet
auction ( http://allegro.pl/show_item.php?item=84181564 ).
Do you know this model? Is it as good as older Grundig Box speakers?
I am looking for a pair of good bookshelf speakers to a small room (ca. 9-10
m^2, very similar to "Room A" on Your web page).Marantz CD-74 will be The
source.Would this 550b be a good solution?
I look forward to hearing from you soon.
I am sorry to tell you that Box550B speakers are not as
good as older Box400 or Box500. But, as you do not intend to use them
in a Grundig chain, you are free to choose them if the price is low.
In fact, the best combination for older Grundig speakers is the full
Grundig chain (V7000, V1700, CD7550, CD7500) or LT chain.
Thank you very much for your

You can choose the Grundig Box 550b or 350a or 353 or 313: this is
the best choice for your hifi chain (they are 2 ways and differs on
woofer size: 3xx = 11cm dia; 5xx = 16cm dia). The choice is related
to the acoustic of your room: if the bass reinforcement of your room
is excessive, you should choice smaller models.
Please, do not buy Box 300/350/400/500 or Professional series if you
do not own a full Grundig or LT chain. These loudspeakers are very
transparent and precise and they need an accurate interface. They
probably will sound unpleasant with your system.
Enjoyed your website, very good.
I have just purchased a pair of vintage B&W DM6 speakers, they are in
immaculate condition and are the best speakers I have ever owned, but could
you tell me what the dial is for on the back please.
There seems to be a shortage of facts about the DM6 on the web.
Look forward to hearing from you.
The dm6 was my first love and still remember it with affection. The dial on
the back part was present only on the first series of dm6 (the better) and
is the control of level of the woofer. Congratulations for your purchase!
I was very pleased to find your website and to join grundig_LT group. We
share the same opinion about GRUNDIG products from 70s and 80s.
I would like to ask you if you could give me your opinion about following
products: receivers R400 and R7500, and amplifier
SV1000 (of course made by GRUNDIG).I was so lucky to get in possession also
speakers 650 and 850a professional and amplifier V7000.
The SV1000, R7500 and R400 are not totally CCI implemented (about 90-95%)
only v20,v30,v35,v7000,v1700 are full (100%) CCI implementation.
However all the Grundig products of years 75-86 are development with CCI
implementation and the results.....
you can listen it :-)
Thank you for your answer.Since I am almost a audio beginner (despite the
fact that I am an electrical engineer) would you please help me to find a
link with some technical details about CCI implementation.
The acronym CCI (circuit chassis interface) has been from
me invented in order to identify the fruit of 20 years of search on a
particular phenomenon. I have seen such type of implementation applied
before only on the Grundig apparatuses of such period. Sorry but I am
not available to supply of explanations but only demonstrations of CCI.
The DSL shipment along
with Grundig CD7500, HiFi Box 300 and other bits arrived safely last Friday
while I was on duty out of town. Thank God everything arrived in good shape!
I auditioned the DSL for
the first time for almost 2 hours today when my sister came over to listen
to some music thru my complete Grundig/LT system (Philips CD960LT, XV7500,
MA50 & DSL). To put it shortly we praise the
system’s ability to give us a pleasant access to musical listening journey.
That may sound simple but certainly not an easy task to carry by any Hi-End
systems. Most of them completely fail to achieve it.
However, I’m not sure if
my audiophile fellows would agree with my assessment since the DSL
surprisingly produces similar open window like the Quad ESL63 from a dynamic
speaker design. But it does a better job than the ESL63 in portraying rich
details and musical expression. The Quad may sound smoother, warmer and
thicker which some may prefer to the DSL.
Even at this stage (not
break-in yet) the DSL already sounds very impressive; music flows
beautifully and very transparent (no congestion) with rich of musical
expression. And I don’t hesitate to say even my favourite ESL63 cannot
provide musical details & feelings like the DSL. Music sounds colder and a
bit more dull/lifeless thru the Quad despite its unique charms! Does anyone
remember Ella Fitzgerald singing a famous Duke Ellington’s composition
‘It don’t mean a thing
if it ain’t got that swing’???
Sorry Quad ESL/ESL63
lovers but I must admit as a proud owner of both models that the DSL gives
you more swing to Count Basie, more heart touching to Billie Holiday, more
soul to Wilson Pickett and more boogie to Deep Purple than the the Quads.
Got the message now?
As a music enthusiastist,
I myself try to avoid to be called an audiophile since I have met so many
who called themselves audio guru/experts promoting perfect sound but in
reality they don’t know what aspects should be justified when listening to
music.Oh what a pathetique!
A number of so-called
audiophiles prefer to analyse the cosmetic aspects of sounds instead of the
basic rendition of musical finesse and expression. Maybe
as most of them are musically deaf or blind (illiterate) and not aware of
what crucial aspects we should look for when listening to music (NOT
sound!). In my humble opinion, harmonics and nuance in music should
be one of the very underlying factors when appreciating Hi-End system
performance instead of the mambo jumble audiophile terminologies which are
irrelevant to the art of music itself. Therefore I don’t believe in
hifi/audio magazine anymore but rather take them as bedtime stories to help
one fall asleep quickly. Agree?
To me perfect sound means
nothing if it does not convey the musical message positively. It’s as simply
as that. My relatively short listening experience with a complete Grundig/LT
system has reminded me how many Hi End systems I have heard missed to
reproduce the true meaningful aspects of music which I now achieve with my
LT system. Of course, it’s not perfect but music is becoming closer to the
heart. Isn’t that what we are all after?
It’s a simple testimony as
a token of my appreciation to the great works of Maestro Ambrosini.
Thanks for your kind comment !
I am very happy to know you
appreciate my effort to give you the best result today in musical
I hope you have more time, in the next few days, to enjoy the system, and
even to test the foam rubber cushion to use between the speakers (see DSL
What type of
electrolitic capicitors You prefer in amplifiers?
It’is not only one type of capacitor good: the type is dependent of employ
Yes Massimo I now ;) beacause I`m testing
a lot of new capicitors in old grundig V1700. In equipment wihich has 20
yers old capicitors isn`t good indeed !!! Now, I know that the typ and
capicyty I must to match very well ;). In V1700 for example the sound is
dependent of capicyty and typ capicitors in supply. In path signal also -
in this place I`m using for example non plar Black Gate typ N and it
working very nice. In supply is working Panasonic FC. New capicitors are
working better in my V1700 and I not discover anything special !!!
And You - what do You prefer ? ;)
>And You -
what do You prefer ? ;)
In Grundig the standard made capacitor !
I advice of don’t modify the CCI Grundig amplifier......
Thank you for your kind
I have a friend who called
me this morning after hearing the LT system yesterday; he wanted to buy my
complete LT system including the Quad ESL63. He is so convinced that he
really heard the best sound out of the ESL63 ever in his life. The big
question for me is about a system replacement from you. Could you deliver
the same equipments (XV7500, CD7500, MA-50)
without having to wait too long?
give you more exciting news.
I just came back from visiting a friend who has very expensive Venture
speakers & pre (passive) / power (single ended tube-monoblocks 15W). His
turntable is SME’s flagship model, 30 with SME V arm and Koetsu Jade MC
cartridge. Total cost for the front-end alone is exceeding US$20,000 + a
phono preamp by Ensemble (Swiss made). I brought a Grundig PS1010, VX7500
and MA-50. We
using the same Venture speakers (using ceramic drivers) to make the
comparison less complicated. The PS1010 is using a Shure V15 Type 3 to get a
more refined sounding to compete against the Koetsu Jade MC ($5,000).
The audience consists of
12 experienced audiophiles who love listening to expensive Hi-End systems
but the shocking news is they all prefer the sound of the humble, cheap
looking Grundig PS1010 with Shure MM cartridge than the super luxury SME
Model 30/ V arm/Koetsu which costs 40 times the Grundig with the V15 Type 3.
We played a few different records with various musical
genre and still the winner is the ordinary looking PS1010. The
listening comparison was so jaw dropping to the audience! I personally felt
with great confidence that the Grundig would win the war and that’s why I
initiated the idea to arrange the comparison test against the SME without
any fear. Everyone was simply astounded with the superiority of the PS1010
to be able to reproduce musical performance, ambience, details, transparancy,
correct note, rhythm & pace in the recording much much better than the
sluggish & dull sounding of the SME. It’s a night and day difference and the
whole game was almost like a joke. We should
ignore SME for being so overpriced and a big failure in turntable design.
What a shameful politic among the Hi-End manufacturer!
Bravo to you, Massimo, for
your ingenious ideas to share some great information about Grundig’s best
kept secrets and your valuable mission to save our financial status by
preventing from buying hifi products who don’t deliver the music. A big
gratitude to you!
thanks for your kind comments.
Just an advise: please do not replace the original cartridge of the PS1010
with the Shure V15
Type 3 or others. If the PS1010 is correctly installed, it reaches the best
performance only with the
original cartridge and original shell.
I am sorry but I am very busy and I can supply a new complete system
(XV7500, CD7500, MA-50) only after Christmas week.
information, I did not change the original cartridge on the PS1010 which you
supplied. I leave
as original to maintain a genuine performance by LT standard.
which was fitted with a Shure V15 Type III belongs to a friend so it is a
different unit. And I am also curious if using a V15 Type IV would be even
better than the Type III which already killed a $5,000 Koetsu Jade MC.
Sorry I just got home from
a long business trip hence the late reply to you.
Today I connected the
MA-50 driving Quad ESL63 with superb results. I use a Grundig XV7500 preamp
Several friends came over
my house to listen to the Grundigs + MA50 with the ESL63 and we all think
they are the finest and most musical sounding system we have ever heard from
Thank you very much for
your kind help & assistance.
thanks for your e-mail. I am glad to know you are well.
Thanks for your kind reply.
At the moment, I have been so amused to hear how the Philips 960/LT could
sound so amazing, more musical & analogue sounding than the standard CD960
or any other CD players I have heard (regardless of price) except of course
the Grundig CD7500 which I am also very pleased with the sound. I have not
received the CD7550 from you so I shall wait to give any comment.
With regard to my speaker choice, I prefer floor standing type. So my
question is whether the best one from Grundig has to be the Box 1500A.
thanks for your questions.
In case of
stand mounted loudspeakers, the best Grundig are the Box 1500a Pro (suitable
for big room) and the Box 850a Pro (suitable for medium room). So it depends
on your room size. The height of stand should be 40 cm.
I bought a LT MA10 50W without phono about 3 years ago. I
have found the performance of this integrated amp really amazing. It has
very good 3D soundstage, very natural and musical. I have recently bought
a used LINN LP12 Sondek Turntable with Shure V15 Type IV Cartridge (original
stylus) and used an Audio Research SP6B preamp as phono stage only. The
result is much better than listening to CD. I found the reproduction
really real when listening to some good recording. Nevertheless, I should
be grateful if you would advise if a single LT MA10 with phono would have
much better result than LT MA10 withou phono stage + AR SP6b as phono
stage. Furthermore, whether it is worth looking for a Grundig PS1010 or
PS1020 turntable to replace the LINN LP12. In fact, I have not seen any
used Grundig turntable for sale in the local market. However, I have recently
seen some used Grundig turntable for sale on eBay. There are PS2000,
PS2500, PS3500, PS3600 & PS4500. Whether they are equivalent to PS1010 or
thanks for your comments.
order to the reach the best performances, the LT amplifier has to
matched only with LT or some Grundig components. The reason is
they are the only hifi equipments featuring CCI technology.
you connect a standard CD player or phono stage to the LT
amplifier, the result is not optimal.
should use only a CD player LT mod. or Grundig CD7500-7550 for
performances. If you are interested, I can supply them.
case you want to upgrade your LT MA10 50W and add the phono stage,
can ship back the amplifier and (if not damage) I can change with a MA10 25w
with phono stage of actual series with 200euro of difference. This price
does not include the shipping cost from and back to Hong Kong.
MA10 (of old series) must be placed on a mechanically rigid surface: the
best sonically result is reached placing the power amplifier on the floor,
instead the actual series have a great difference : is optimized for no
sensibility of surface (also soft surface)!
also supply the PS1010-PS1020 with original stylus Shure n75gt2 NOS(New Old
Thank you so much! Today I received an old cd35 and look bad but play well.
The amazing thing is that cd35 is so matched with v7000 + 850a. I have been
played with Philips 850MKII and my father's Burmester 937, and sound a
little odd. Only one thing I am not comfortable is the cd35 could not select
track, I should play from first track to the last. By the way, please give
me a suggestion regarding 7500 and 7550. Are they far better than cd35,
cd7500 especially? Because cd7500 has Grundig cable. I would like to say
"Thank you" again, I got a good stereo was due to your instruction.
thanks for your comments.
The CD35, if in good conditions and well installed in a Grundig/LT
chain, should sound far better than any Philips or Burmester. Please
note that the V7000 offers the best performance when placed directly
on the floor (and need of correct cables).
The CD35 can skip tracks, buttons are under the display.
CD7500 and CD7550 could be a bit better than a CD35 but, as they are
old machines, it depends on general conditions.
The CD7500 features the "bonus" of original Grundig cable. :-)
In primo luogo, grazie per il vostro Web site che il nome information!My ?
Robert e vivo in Taiwan. Sono un allievo della High School. Poich?il mio

equivalent to cd7500 and cd7550 for CCI implementation. If you would have

Yesterday, I have received Grundig SL 1000.
The German seller informed me the following specification.
Music max: 70 Watts.
Load rating: 50 Watts.
Transmission range: 38...26 000 Hz
4 ohms. 2-Way, Trans over 1600 Hz
I was already known that it is 2-way but it sounds as if it is 3-way speaker
. As you know,on the tower of SL 1000 there is a tweeter between two
speakers those are the exactly same external apperances. But I could hear
that the upper speaker was doing like middle-toner and the lower one was
sounding like woofer. Is normal and right ? I just tested SL 1000 for few
ten minutes to check the proper operation.
Any suggestions and comments for SL 1000 would be very appreciated.
congratulations on your purchase of SL1000. :-)
SL1000 is a very good loudspeaker in a full Grundig/LT system. It is
similar to my DSL but the SL1000 lacks the bass extension and power
of DSL. The SL1000 is suitable for small rooms or medium/big rooms
with excessive bass reinforcement.
SL1000 is a directive loudspeaker in the midrange so, it is very
important the height of listening point: the height of the ears must
be 80 - 90cm, lower than usual.
The SL1000 is a true 2 way: the lower woofer seems to sound different
but it is only the different position in the tower.
appreciate your so much valuable Grundig informations.
read some your new email messages corresponded with other peoples for some
topics and found very interesting things that you have mentioned as
" ...... V7000 is CCI fully
implementation. All modification to this amp goes to a worse quality.
R7150 is good but not so good.
On v7000 and v30 is present a
little detail (CCI influent) assembled with an error (on more exemplair).
I have available to correct this error (no cost for members of G/LT
mailing list ) . For this you can see also the italian page :
unfortunately I can not understand Italian at all as you know.
give me the detailed information for the CCI corrections of V7000 and V30
mentioned 10 Euros for something(???) in your Italian homepage. Is that
fee for the information or what ?
thanks for your email.
I confirm there are some V7000 and V30 with a small detail wrongly
assembled. Unfortunately it affects sonically the
amplifier as this small detail is related to CCI. I can check and fix the
problem in my laboratory. But you have to ship to me your
V7000 or V30 (and pay also for return back). I fix this problem free of
charge for members of our G/LT group in a single V7000 or
V30. If you have to check and fix more than one V7000 or V30 it costs 10
Euros each. I am sorry but, if you want to check your
V7000 (the check is free of charge) you have to pay the 2-way shipment
costs from Korea. :-(
Thank you for the details.
Do you think sonic differences after modification of v7000 CCI faults
could remarkably be realized ? As you know it needs not only
quite a lot of shipping expenses between Italy and South Korea.but some
possbility of damages during long transfer.
Anyway, about 70 Euros for one way to Italy by normal air parcel. for my
packed V7000( little less than 10 kg weight including
proper packing materials)
Do you have any infomation of shipping cost for returning my
v7000 if I will send it to you ?
sonic differences after modification of > are remarkable: 20/30%
Shipping cost to return the V7000 from Italy to Korea is about 150Euros.
What is the exact meaning of " V7000 CCI fault (if present) " ? Are
there any V7000s without CCI fault ? All V7000s that I have were made in
As you know a Grundig_LT member recently posted a message concerning
about the heat transfer material such as MICA disk used for power Tr
of V7000. All my V7000s use some kind of compound(white color) not
MICA disks for heat transfer. Do you think that V7000 from different
lots may be there are some minor changes giving some effects for CCI
implementations ? If the above assumption may be true then could you
check whether the CCI fault is present or not by checking some
detailed photos of my V7000 ?
Many thanks in advance.
the V7000 CCI fault is a small detail inside the chassis that
sometimes is assembled wrongly. There are same V7000 without this
problem (the detail is assembled correctly) and same V7000 affected
by this problem (the detail is not assembled correctly). I am sorry
but I have to check personally this problem as it is very difficult
to see in a photo.
I think there are no changes in sound caused by mica or other heat
transfer material. But I know some changes could happen if somebody
open, repair and close a V7000 (or other Grundig devices). Just tight
the screw of the cover strongly or slowly and the sound will be
My name is Konrad xxxxxx. I'm from Poland. I
just have purchased V 7000 and I've found it amazing. Previously ! was
tuned for telefunken and braun gear and in general german equipment. in my
opinon it sounds better than japanese (or more precisely non DIN) HiFi. I'm
not electronics specialist but I think there had to be some kind of
unification of parameters in "DIN zone" so the the whole system sounds
more cultural and less fatiguing. But I was not interested in Grundig at
all. First of all grundig has bad opinion in Poland because during
communistic times it was (together with thomson) the only international
audio brand functioning in socialistic "market" and because there was only
very few cheap models of radiorecorders produced (on license), today's
Poles see grundig as not serious company. The recent Grundig's and
Thomson's production does not make any change in this area : )
Some months ago my friend bought a set of box
40 and we connected it directly to my CD Telefunken HS 950 (it has a
regulated output) and... you can imagine what happened... it seemed like
evangelical miracle: a deaf one was healed. I did not realized that I have
so perfect CD! Then I started to seek some knowledge and I have found your (and
my fellow Pole Greg's) website. You both dicovered grundig's miracle,
moreover Greg praises some part of Sanyo production for its transparence
and fidelity. Greg told me that you have contacted but linguical bareers
are to high. Pity. Greg says that he's able to improove selected grundig
gear to play even better, you say oppsite: the bricks are perfect, do not
touch it. greg seems to be serious specialist and judging on what he
writes on his website he knows what he is talking about. Aren't you
curious of this? My idea is to say "check the issue".
Therefore i propose a little deal: I will order
full GAT (Greg Audio Tunning) of V 7000 and will send this unit to you on
my expense. Your role is to tell your opinion and send the amplifier back
to me on your cost. I hope something good to come out of this.
I'm glad also you enjoy the Grundig sound. Thank you to share with me your experience.
A lot of people are discovering qualities of old Grundig equipments in
Italy too. As you can read in my website, in order to reach the best
performance, I suggest to use a full Grundig chain without mixing them
with other equipments (even if they are "DIN HiFi").
I started to study Grundig equipments 20 years ago and my knowledge in
their technology has helped me in development of my handmade Linear
Transfer products. This is the reason I suggest to not modify Grundig
equipments. In fact, I have mailed Greg this mail:
as I can see in your website, you cite my name without any
permission. Please, you are requested to remove any reference from
your page. Thank you for cooperation.
I would like to remember also that CCI mark is an intellectual property of
And Greg has removed all reference to CCI and my person.
However it is difficult to speak about these topics
in a non native language.
If you come to Italy, you are welcome to my home and you can bring with
you the V7000 GAT and compare it to a standard V7000 in my fully optimized
Grundig chain. Or, if you prefer, you can send to me the unit and I will

would not appear biased.
A year ago I did purchase a B&W DM6
loudspeaker. I am very satisfied with the speakers; they sound wonderful.
When searching on the internet I came by your website and find you do
appreciate them just as much as I do. However, I am not satisfied with the
Luxman LV 103 amplifier and Quad 405 I do use (in fact they are both
broken now), so I am looking for some good advice for an amplifier who
really fits well with these speakers. I wonder if you do have some advice
If you do have some time for an answer I will
appreciate this very much.
Hendrik xxxxxx (Amsterdam)
I advice a standard Grundig v1700 for your DM6, but the better solution is
with a cd CCI (cd7550-cd7500-cd35 Grundig) .
Your Dm6 is the first series (with level control also on woofer) or the
second series ?
My DM6 is the second series. Does it make
The midrange is different on first series (totally
kevlar included the dome) and this range of frequency is better.
I advice to listening with the upper grilles but without the lower
grilles for the better results.
What do You think about performance of Grundig amplifier model V7500?
Ps. I`m a fan of Your cci secret, because I love DIY audio :) I will be to
study schematics and construction old Grundig equipments.

Hello (what you name ?)
V7500 have only a partial CCI implementation . It’s good but not one of
for a new equipment this summer I saw your website. Because I am not very
technical I was surprised by your attractive simple recommendation of
holidays I foundt a V 7000 so I bought it, together with a cassettedeck
7200, so my holydays were wonderful, but I do not yet.have the amp in my
home. I have a few questions:
father for Grundig on Google I found a Polish website (www.gregaudio.
republica.pl), also with information about Grundig and ICC. I mailed this
Grzegorz, but because the website is only Polish and his English is very
bad, I cannot get exact information if he has the same ICC principles has
as you have. Do you know this website and his activities?
* He recommendates the
V7000 but he also does modifications (!) at the amplifier. He mailed me
and advised also the Reciever R 7150, and mentioned it as "far better than
7000". What is your opinion?
* It is
difficult for me to get a Grundig 850, 1000, 1500 in Holland, and also
on e-bay. For I have a not a small room, I would try to get a B&W dm 6
now. Could you tell me if this is a good combination with the V 7000? I
listen mostly to old mono and stereo records, which needs a clear reproduction
(otherwise they sound to warm or veiled). If this is not a good
combination for my records, can you recommend another clear-sounded
pickup now is a MC. So I have to use a step-up ( I have now a simple
Lentek) for the phono-input of the V 7000. Would this have a negative
influence on the sound- image of the V 7000? If so, can you advise me
another step-up? (and if I do not succeed in getting a Shure MM!).
you give me the address of people in Holland who have LT-products so
that I can listen?
I want to buy LT-products, can you give me a price-list?
That is enough for now, and I hope you will answer me soon.
Perhaps I have later some more questions.

Dear Mr. Massimo Ambrosini,
because of your knowledge of Grundig I would like to ask your advice for the
best Grundig FM tuner.
I have already the ST 6000 unit, and it sounds much better than any digital
tuner I have heard. The ST 6000 is analog (IF: LC filters), but with digital
Is there any other Grundig that would be even better ? For example the old
units from around 1970. Or the mini tuner MT 100 (ca. 1980 ?) ?
The better Grundig tuner is the T7500.
All the series "7000" are CCI implemented and then very good sound (much
better of 1980 series). T7200 and T7500 are also tuner PLL (very good
I find your website very interesting.
I wonder if the Grundig Hifi series of 1979/80 solve the CCI problem. I
normally listen to the combitation of SXV 6000/ mxv 100 + aktiv boxen XSM
3000 or XM 400 and the sound is georgeous! Very natural and
neutral.I find output stage MA100 / A5000 highly advisable. Is it worth
preamps for the most modern XV 7500 or there is small difference between
Box M300 + receiver MR200-2 is also astounding. What´s your opinion?

thank you for your positive comment on my website.
The Grundig HiFi series of 1979/80 is very good but it solves only
partially the problem related to CCI. It was a transition series but
better than most of actual audiphile products.
The XV 7500 is similar to SXV 6000 but the CCI technology reaches a
higher level. Probably, in your combination (CCI medium level), there
is a small difference between them but, if you find a XV 7500 in good
condition, you should try it (in combination with Aktiv Box).
MA100 / A5000 are good amplifiers but the best Grundig amplifiers
(relating to CCI) are the V7000, V20, V30 ,V1700. But I agree with
you: also if the CCI is only medium level, Grundig combinations are
Can you send me more information about the upgrade ?
Thanks Johan xxxxxx
as you can
see in my website, my ESL63 upgrade is the solution
to a problem that spreads itself in the whole hifi link. This the
reason I suggest to assemble a complete hifi system optimized for CCI
instead of trying just one component.
You can start from suggested amplifiers and sources: Grundig V7000,
V20, V30, V1700, Grundig CD7500, CD7550 or LT products.
The cost of upgrade for ESL63 is 300 euro but if you have the chance to come
to Italy I can show you the improvement comparing to the standard ESL63 and
the improvement using them in a hifi system optimized for CCI.
I got few days ago CD960
Philips, It plays quite good, but little mechanical (worse then my cdpro2
with nos DAC) andshelf is not working. I have to take cover down and
put cd manualy. I little read about mod for CD960 and wondering how
much it cost?

Hi. First - I really love your site.It is not only fun but
also very educative. Funny thing is I had quiet a few or your favorites
components (quad 63, DQ10 Rodger LS3/5A),and it seem we had some similar
experience (and test). Since you are the first and only person that my two
componenets (Krell & DQ10) are some of his most favorates,I don't know
about anybody better than you to hear from.
My dilemma is - I'm going on budget right now,and using the Dahlquist
DQ10, and I have an Opportunity to purchase the Krell KSA 50, and I'm
wandering what do you think about this combination? The seller said it is
a peach match with the DQ10,but as you know,he is the seller?! (he might
be righr,but he is also a little biased). Do you think it is the best
match I can do for no more that $1000 on the Amp? (My preamp is the
precision Fidelity C-7A ,phono only). I would love to hear from you, and
really looking forward for your thoughts and advice. I think my wife is
going to kill me - as i'm spending too much time on your site.But hey - it
is fun!!!! Best regards.Elli
thanks for your positive comments on my site. As
you can see in my pages, the old Grundig amplifiers (v7000, v1700, v20,
v30) are my favourites and, in my opinion (and after some test comparisons)
they are even better than Krell. Unfortunately they have never been
distributed in the U.S.A. and they were produced only for european
voltages (220VAC or 240 VAC). In this case you can go for Krell KSA50.
You will be not disappointed.
Thanks much Massimo for your time and input. I'm going to look for
either Grundig Amp or turntable - who know - maybe i'll fing a good deal
in the U.S.A voltage.I'll let you know in this case. Thanks again
Little bit a long time has passed since I have corresponded wiith you.
I now have some more Grundigs. I will soon upgrade my photos in the yahoo
I introduced Grundig CCI and LT system to a online internet audio forum in
Some peoples are interested in the Grundig and LT stories anyway.
Fortunately I recentely could have a chance to buy a set of box 300 .
It has not only very clear and transparent sound along with mid -high
range but also quite quite cute in bass-extension.
Attached the photos of my box 300. Could you please check whether it is
good and normal compare with original one especially for the edges ?
photos of your Box 300, it seems they have not any external problem. Please
consider that Box 300 are very critical in placement and set-up.
- Box 300 must be placed on a shelf (max. height 50 - 55cm), look at picture
at my website: http://motxam.interfree.it/Atop.html
- Box 300 do not fit well large rooms: they are perfect for small rooms
- The listening point must be placed near the rear wall (40cm far from the
- Do not remove frontal grilles
- Remove completely the felt foot that I can see in the photo and cean well
any residual of ahesive.
Please, let me know your impressions.
Thank you for your very valuable comments.
Is felt foot not original one ?
>Is felt foot not original one ?
I don’t know, but no felt foot is the better solution. :-)
Thank you for the prompt reply.
Could I ask you one more question ?
Is sound quality(?) of box 600 equivalent to that of box
500 and 650 pro when it is matched with v20 or v7000 ?
The box 600 is very good speaker but a little bit worse of box 650prof. and
(if placed on a shelf of 50-55cm) box 500.
I´m a Grundig Fan too !
Do you need some pix of a
Monolith Soundwall 190.
I´m the proud Owner !
nice to hear you are a Grundig fan too.
Can you list the components of your complete hifi system?
Have you ever tried the Grundig Aktiv Box 20 or 30 in your room?
They could surprise you. :-)
Really i tried the prof 30 monolith80 and monolith50 too .But in my opinion
the 190are simpy the best.
AVM V3S preamp with Accupowersupply CD1P and DAC3.
have you ever tried the Grundig preamplifier XV7500 and CD7500 in your chain?
I have tested several Grundig components (including monolith series) in
years and, in my opinion, the best are:
Integrated Amplifier V7000, V1700, V20, V30 CD Player CD7500, CD7550
Speakers: 650Pro, 850a Pro, 1500a Pro
Bookshelf speakers: 300, 350, 400, 500
Turntable: PS1010, PS1020
The aktiv box 20, 30, 40 and 50 need a modification to reach the best.
Yes I like the 7500 preamp and the cd7550 too.
The sound of the 7550 cd is very warm it has the cdm1Pro drive (The best of
all Drives with glass lenses!) and sounds a little bit like Marantz.
Do you know some necessary modifications for the Grundig active loudspeakers.
I´m very interested in.
By the way -if you need some manuals or schematics may be i can help you !
if you come to Italy I am pleased to invite you and have a listening
session to my Aktiv box modified compared to standard Aktiv Box.
Next 21st May, me and my friends of Italian forum, we will meet at 2nd
Grundig Day in Ravenna: we will compare several Grundig equipments and my
own modifications and products (Linear Transfer range). Where are you from?
I found your web site while I was looking
for some information on Grundig tuner T7500. During searching your web site
I realized that you are quite focused on cd-players and amplifiers. How
about Grundig's tuners? Is there any sense to buy it?
Presently I'm looking for some tuner for me
and I found that one in a very good condition. The question is: should I buy
it or leave it? Price is about 50 euro.
>Price is about 50 euro.
A great tuner for a little price…..:-)
I bought the Grundig Super HiFi Professional Aktiv Box 40 for myself
recently at eBay for 400.- EUR.
You can tell to me what those ones cost once again.
Those ones have a very good sound, only the middletones could be a little
A lot of thanks for your answer.
the Aktiv Box 40 are very good loudspeakers. Also the midrange is good but
the result can be affected by
other components. How is your hifi system composed?
Please, remember to use the Aktiv Box using their grilles because this too
could change the middletones
I practise the boxes at the computer and hear my MP3´s. I employ as Player
the Windows Media Player 10 at
which one achieves very good sound results about equalizer and SRS. Of
course it would ring differently
if I used a good booster, however, I lack the place for this purpose. You
can say me what these boxes
cost before 30 years on the market?
To Thanks for your answer and relief.
With friendly greetings
I strongly suggest to use your Aktiv Box with Grundig XV7500 preamplifier
and Grundig CD7500
(or CD7550) cdplayer.
The actual quotation for Aktiv Box 40 is 600 Eur. The old price (1979) was
800.000 italian £ = 400 Eur !
I will make an effort to bring the devices recommended by you and to
practise the boxes with that.
Me would interest still, from where your interest and competence for Grundig
devices comes and which
boxes you use. What surprises me however too, is, that the boxes 1979 only
400.- EUR ( the pair? )
to have cost and to be acted today for 600.-.
From where does this increase come?
> Me would interest still, from where your interest

> Grundig devices comes and which boxes you use.
I studied so long Grundig devices as they are very good, even better than
the "so called" high-end hifi.
I use several kind of boxes in different rooms and my favourites are: LT DSL,
Grundig Box 300, Grundig Box 850a Professional.
> What surprises me however too, is, that the boxes 1979 only 400.-EUR
> ( the pair? ) to have cost and to be acted today for 600.-.
> From where does this increase come?
Also the famous Rogers LS3/5a 15ohm were priced 175 EUR in 78-79 and
nowadays their quotation
is 800-900 EUR!
I red carefully your opinion on recommended components.I would like your
opinion on my system regarding possible
upgrading if it's not too much
trouble for you.
My system consists of a PLUTO 12a turntable a Pluto 5a special tonearm along
with and a Koetchu Urushi.
The pre amp is ML 26 and the phono stage is ML
25. Cd player is the Audio Research cd 3 and a Nacamishi Dragon
the music sources. The amp is a stereo ML23.5. All the wires are NBS
Master( Interterconnects, speaker, power) Finally the speakers
are the KEF 107/2.
The later I own them since 1987 and I'd bought them upon a trip to London.
The ML's from NY back in early 90's and the rest date back a couple of years
I would very much appreciate
your expert opinion of these items.
Thank you very much in advance for your kind reply,
I am sorry but I am not used to
give opinions about other products than my recommendeds. You can find in my
the components that I suggest:
and especially, if you ask for
A simple Grundig V1700 or V7000
with a CD7500/7550 and PS1010/1020 is better than ML/AR. You should try it.
i found on Your site informations
about the old grundig CD Player - the cd 7550. If I can, I have a question
to You. Do You heart the Philips cd 304? It's a player of the same Years,
and the construction is the same, the diferent is the Toshiba Ram in the
Grundig CD 7550, all others looks the same.
Thanks for the answer
Grundig CD7550 is apparently
similar to the Philips but some technical solutions and the sound are
Thank's for the answer :)
I heard yesterday the grundig
CD7550 it's play very well, and the sound is much better as the of 304 :) I
was always thinking, that the 7550 and the 304 ist the same player, I had
the 7550 over 2 Years, and after hearing 304 I don't heart the 7550 :)
Thanks fot the info :)
someone offers me an Ampliwire 100 Poweramp and an EC1 Preamp combination.
But i can't find any infomation about this produkts in the internet. Please
send me an Soundtest or some one else. What do you think about this produkt?
Sounds the electrocompaniet as good as the ECI series?
Thanks for your help!
Greetings from germany
I am sorry, but I am not used to give opinions about other products than
my recommendeds. You can find in my website the components that I suggest:
I am sourcing a Philips CD960 CDP. Noted that you are using
it with a linear transfer mod. You you mind advising me what is a linear
transfer mod and how it is implemented.
the Linear Transfer mod. for CD960 CDP does concern the solution of
C.C.I. (Circuit Chassis Interface). I am sorry, but I do not intend
to unveil this technology as I spent so many years studying this kind
of phenomenon. The only thing I can say is that the LT mod. does not
concern zero-oversampling neither modification in output stage
neither anti-jitter circuits...
Great web site, thanks for sharing your knowledge.
I currently own Audio research VT60, LS8MkII, Sonus Faber Minima Amator, Avi
MC4 cd. I would like to upgrade the amplifier and I am thinking about a
Classic 60 or V70. What were your impressions of these amplifiers.
Keep up the good work
as you can see in my website, I stronlgy suggest specific products
because they only reduce the effect of the C.C.I problem.
If you like Audio Research Classic series you should buy but I
recommend different kind of products:
but I mainly (and strongly) suggest:

Hello, my name is Josh. I have a CD960 from
1987 that works well, except for a tracking problem. Would you know of
anywhere that sells replacement parts for old CD players-and that will work
on US 120 volt current? I'm also curious about what Linear Transfer
modification is-I've heard many things about how to modify this CD player, (for
example, switching the TDA1541 for a PCM chip) but no one over here seems to
know anything about it.
it's no easy to find replacement parts for old
CD-players. You can
find in Ebay old CD-players and using them as spare parts.
The LT-mod for CD960 involves the solution of the C.C.I. problem
(Circuit Chassis Interface).
As I worked very hard and so long to understand what the C.C.I. is, I
do not intend to offer any technical explanation except of what you
can read in my website, sorry.
I can apply the LT-mod to your CD-player but you can appreciate the
improvement only in a full hifi chain solving the C.C.I. (Grundig/LT)
congratulations for your very interesting web-site! I own a pair of old
Grundig Aktiv Box 40 but I have no cables to connect a preamp. Can you
advise me what cables are best suited and where to get them? Do you sell
Mit freundlichen Grüßen,
if you can not find Grundig interconnect cables, you could build them
using DIN plugs and the standard grey/black cable (as you can see in my
page at bottom):
In case you are not able to build cables, I can supply them (with DIN plugs)
cost is 4 euro per meter excluding shipment.
I've sent you an e-mai a couple of month ago, concerning my
broken v1700 and the v7500. Now I had a little time to try to repair my
v1700. I found that some transistors and two diodes (D702,D703) were
defective . I was able to get the transistors but no one can tell me what
the indication of the diodes is. Could you please lookup the description
of the diodes or send me the schematic diagram of the v1700.

mailing list of enthusiast of Grundig LT :
How do you think about Grundig preamp SXV6000 ?
Can you post the question on
new mailing list ?
I answer to you on mailing list.
Thank you so much again for your interests and suggestions. I recently got a
V20, V1700, CD7500, Box 650a Pro and failed to get
Box 850a Pro in Ebay auction, Germany. During the bidding for the above
items in ebay auction, Germany I met many Italian competitors. I could
easily imagine that your strong suggestions for certain Grundig vintage
audios to encourage them quite a lot. I regret that I may give them(Italians)
some stresses during the biddings...^_^
The condition of V20 amplifier that I received from Germany was not so good
but fortunately it has almost been recovered perfectly since I met really
great electronic master engineer and technician having 35 years experiences.
He is a marvelous electronic engineer and technician. As you know I bought
modified Aktiv Box 30 since I didn't understand Aktiv speakers exactly. The
former owner of the Aktiv Box 30 also didn't aware of the modifications. As
your suggestion I am going to keep it as spare parts but in the mean time I'
like to try to exchange the DIY crossover to another commercial ones
available for experimental purpose. Yesterday, fortunately I found a very
nice and well maintained Grundig Box Pro 1500a in Korea. I'll bring it
tomorrow. I am going to match V20 + Box Pro 650a and V1700 + Box Pro 1500a.
Upon your suggestion, Box Pro 1500a shoud be declined backward. Could you
give me some more details for how much to decline it.
Anyway,the next step that I would like to do is enjoying the sound of old
Grundigs lot lot lot... I am apperciated very much for your valuable
suggestions that induced me not to spend a lot of time to try to find nice
I know there are a lot of Italian competitors during bidding for
Grundig items in Ebay auctions. I expect their number will grow up in
a few years.
Grundig Box Pro 1500a should be declined a few cm. They are highly
directive speakers so you will find easily the right declination.
Thank you for your comments. Please, consider that these Grundig
components are not only "nice audio devices" but the best ever
produced. In fact they are the only devices solving the C.C.I.
problem (excluding Linear Transfer, but LT is produced only in small
First excuse my English, which is not the
best. I live in Germany and I am electronic engineer.

Eventually I have a Grundig V20 amplifier, Aktiv Box 30,
Box Pro 650a and Box Pro 550a.
As a novice I' like to express that V20 + Box pro 650a
combination gives me the best feelings among them for about a week

And it is little bit curious for me that I feel a lot
differences in sound propensity between Box Pro 650a(3-way) and Box Pro
550a(2-way) even they are almost same sizes and external shapes.
I wonder whether the both of them are retaining the
original sound quality or may be some degraded in.
Also I do not understand the function differences between
active amplifiers like in Aktiv Box and the passive networks in Box
Which type is more adaptable or effective for my V20
Could my Aktiv Box 30 built-in amplifier be easily modified
to the Linear Transfer modification as you mentioned ?
congratulations on your purchase
of Grundig products.
Grundig Box Pro 650a are
optimized for placemement on stand. The Pro 550a are optimized for bookshelf.
This can explain the
different acoustic frequency
response. But it is also possible that speaker components are damaged or
degraded due to the age.
To really evaluate these
components I hope you will find a Grundig source (CD7500 or CD7550).
Passive speakers (650a, 550a)
must be connected to an amplifier (like your V20). Active speakers (Aktiv

I can modify Aktiv 30 but you
have to ship the speakers to me, here
in Italy. The cost of

Thank you for your very valuable comments.
Oh sorry that I didn't mention Grundig CD7500
player which I got already.
I have used very good condition of CD7500 player
with original cables as source for my brief evaluation.
I can now understand why the combination of V20 +
Box Pro 650a is better than the combination of V20 + Aktiv Box 30.
But I still have some questions about the
combination of preamplifier (XV 7500) + Aktiv Box 30.
You mean those combination doesn't need any power
amplifier further ? The preamplifier output could be connected directly to
Aktiv Box ?
So Grundig Aktiv Boxes are just dedicated
speakers for Grundig preamplifiers ?
I think that the former users of Aktiv Box in
Korea mostly did not realize such an important facts.
Any comments should be very helpful for me anyway.

Active speakers do not need any power amplifier further.
The power amplifier is built-in. You must connect the preamplifier output
directly to Aktiv Boxes.
> So Grundig Aktiv Boxes arejust dedicated speakers
> for Grundig preamplifiers ?
Yes, Grundig Aktiv Boxes are just dedicated for Grundig preamplifiers.
You may be confused for my questions concerning
about Grundig Aktiv Box 30.
I am not still sure but my Aktiv Box 30 which I
bought in Korea may be already modified one.
Since it has no connections for amplifier
except R+L connectors as normal passive type speakers.
Which passive network (such as Box 850's or
650's etc) may be very compatible to my Aktiv Box 30 if I would like to
use it as passive type speaker.
Any comments should be very valuable for me.
please, can you send to me a photo of rear panel and connectors of your
Aktiv Box 30?
sorry to tell you that your Aktiv Box has been modified:
removed the amplifier and active crossover network.
sorry to tell you that it is not possible to replace them with a
crossover network featuring the same Grundig original
suggest only you can keep woofer, midrange and tweeter as
replacement parts for other Grundig Box Professional series.
I would like to know more about the LT-mod to my recently bought CD960. Can
you provide more information to this humble DIY?
for CD960 involves the solution of the C.C.I. (Circuit Chassis Interface)
As I worked
very hard and so long to understand how the C.C.I. works and the solution of
this problem, I do not intend the offer any
explanation except of what you can read in my website.
am really sorry.
I was surfing the internet and came across your site, and wonder what does
this CCI (Circuit Chassis Interface) project involve. You come up with
interesting results and findings, but did not bother to elaborate about the
"problem" and the so called CGI solution. Can you explain what this "problem"
concerns and describe what this 'circuit chassis interface' is. Maybe people
can understand your vision and Grundig's for that matter and why this is not
done anymore or been done by other manufacturers. Seems to me that this must
be some electrical modification that should not been overlooked by the major
companies and if so they are pretty stupid, and only Grundig has come up
with this solution for the 'problem'. Why did Grundig didnot use this
anymore in their later products. And why is it so important that the
original cables should not be changed, why is it so crucial to the solution.
I am sorry, but I have worked very hard and so long to understand how the
C.C.I. works and the solution of this problem. So I do not intend the offer
any technical explanation except of what you can read in my website. I am
It is very difficult the engineering of a system solving the C.C.I. but, if
you open it, apparently it looks similar to other hifi products. This is the
reason why other manufacturers have not copied the solution of the C.C.I.
from Grundig products.
I do not know why Grundig has changed its production, probably they have
replaced the engineering team or they outsourced the production. I tried
several times to contact the old Grundig engineering team but I've never had
The C.C.I. can also explain why cables sound different...

Yes, The old grundig sound was much better than its contemporaneous hifi
systems on the market and even nowadays its hard to find ordinary equipments
tat match the quality of them.Not only amplifiers and speakers were
unrivaled but also cassette decks and tuners could record and produce a
superior sound. I suggest you should launch a new hifi series sharing the
same philosophy or convince the new grundig engineers to follow the same
updated line again.It would be a great success. To improve your website it
would be a good idea to complete the grundig story with more good products
and photos. Also include more affordable items in your recommended products.
I have the the old grundig mini hifi system mxv 100, ma 100, mcf 400,
aktive bosx xm 400 and wouldn´t change it for a modern standard one.
Greetings from Spain.
thank you for your message and your suggestions. I am happy you enjoy
the old Grundig sound. I am producing some hifi components sharing
the same technology in order to solve the CCI problem (circuit
chassis interface): they are called Linear Transfer. The line
includes a preamplifier, two power amplifier (25W or 50W), the
modification for CD player, the floorstanding speakers. I am not in
relationship with new Grundig engineers and I think it is hard to
convince them. You can find more photos of old Grundig products in
the database of our forum. The "recommended components" list includes
only products can assure a good result (but worse than Grundig). Saludos
I read your
article on hi-fi.
Is it still
possible to locate the Gale speakers GS 401 or 401A.
Any idea what a
fair price for a set of two would be?
Gs 401 are a very good
speakers but a little bit worse (for example) to Dahlquist DQ10 (and to
some models of Grundig).
In Italy the price is around
to 700-800 euro.

Good series of 1980 but not the
I couldn't help but read your posting some months ago. I had a
secondhand V15 type III cartridge which I sold off two yrs ago (it was
included with a turntable that I didn't need). After selling it, I read
reviews about it being one of the best V15's around. The only review to
the contrary was yours. Well now I must say I agree with your review.
I recently got ahold of two V15 type III cartridges and two new styli
under Shure's trade in program. Shortly thereafter, I found a
curiousity item at my local electronics shop. The old-timer saved some
old cartridge bodies, one of which was a Shure Tracer 1 with a broken
stylus. Needless to say, I cross-referenced it and found the M97HE
stylus was a match for it. I bought the NOS stylus (from
stereoneedles.com) along with finding a M97 sales brochure.
.........OK, on to why I'm writing this. Well, my friend (who uses a
V15 type II with NOS stylus) and I decided to compare his type II to the
type III and M97HE era IV (which compares to the V15 type IV). Well to
my amazement, the M97era IV actually sounded the best overall! I'd
even say the type II sounded pleasing too though a bit weak on higher
frequency details (but for some very strange reason, the type III with MR
stylus is just a bit too bright on the top end and not as rich sounding as
either the II or IV). Oh, and one last note: I have a Shure V15 IV
body without stylus (and am seriously considering the NOS genuine stylus
for $159 - yet am going to be hard pressed to consider changing that M97
era IV now that I've heard it). My thoughts.
Your thoughts are
The M97 IV have a sound very similar to V15 IV and both are very good pick
I have the opportunity to buy a Philips CD303
which looks very similar to the Grundig CD7500. Do you recommend?
Or do you prefer to buy a CD7550. I could also
buy a Philips CD960 here in the Netherlands for 100 Euro and modify it to
Any suggestions on the best option for me?
Rest of my setup: V7000 and Box500/Box450
The Philips CD303 looks very similar to
the Grundig CD7500 but it is
very different. Do not buy it.
First step: buy the Grundig CD7550 (with a
Grundig cable) and enjoy
100 Euro for a Philips CD960 is a good
price but the LT modification
is quite expensive
Hope this helps.
I have bought the CD7550 (for 50 Euro),
Germany is not so far for uw. After warming up thoroughly it functions
well, and sounds very good (full, open sound). It seems like the V7000 is
opening up also with this CD player compared to the former one (high-end
At least I have a full Grundig setup now, and
it is very enjoyable to listen to...
The only thing I miss now is a Grundig cable,
do you know where I can get them as Ersatzteile or something?
I am very happy you enjoy the sound of Grundig
setup compared to high- end stuff.
You can look for Grundig cables only in second hand
market or ebay.
As an alternative:
Saw your post about owning the Studio 3. I am
thinking of buying a used pair and was interested in your experience with
these. I have proac tablettes, EBT's and Sc1's so I have some experience
with the brand.
I under stand these are also called 'EBS', true. Do
you know the original pricing? I have checked the blue book.
comments are appreciated
The Studio 3 EBS (extended
bass system) is different model with the same drivers of Studio 3 but in
different box for maximum extended bass.
Sorry but I don't remember
the original price.
Sorry to disturb you again.
I found another Grundig speaker in Taiwan.
It's BOX 660A.
You have said Box650a is good.
I wonder whether Box660a is as good as 650a.
And how much does it cost now?
I am really eager to have a Grundig speaker and enjoy the Grundig sound.
Thanks a lot in advance.
I am happy
you have found a Grundig speaker in Taiwan. As you can see
website, the 660a is just a bit worse than the 650a:
told you, the old Grundig went bankrupt in the late
650a, 660a and others speakers are out of production. In
Ebay quotation for these kind of speakers is 100 - 150
remember to match the Grundig speaker with Grundig (or LT)
and source to enjoy its sound.
Thanks so much for your response,and it is very appreciative and helpful. I
didn't response by now,as I'm on budget expanses ,and can't afford those
expensive items, and I didn't want to bother you without a real question/advice.
However,I think I saw one of your recommendation the Dynaco ST-70 - Do you
recommend the upgraded with Alan Kimmel-designed circuit as offered by
Welborne Labs - I see it for about $700 and wanted to buy it?; Or is there a
better modification for the ST-70, or can I just buy the stock one? I can't
find you web-address - could you please send it to me? Thanks again Massimo
for your kindness for taking the time and writing to me. If you are too busy
- even a short advice is more than welcomed. Thanks again.Elli
I've never listed the Dynaco in my recommended

I found one pair of grundig speaker BOX-5000 in Ebay of
Do you have any idea of this speaker ?
I wanna own a Grundig speaker but I am afraid of getting
the wrong one.
grundig speaker BOX-5000 do not sound good.
- Bookshelf installation: Box300, Box350, Box400, Box500.
- Stand Mounted Speakers (small room): Box650a, BBC LS3/5a
- Stand Mounted Speakers (big room): Box850a, Box1500a, Box800, Box1000.
- Floorstanding Speakers (small room): SL1000, SL1000a.
- Floorstanding Speakers (big room): Linear Transfer DSL. Obviously, as
you can see in my website, I recommend source and
amplification Grundig or Linear Transfer.
Dear Massimo Ambrosini,
Deeply appreciate your rapid reply.
I finally got a pair of Spendor S100.
It sounds great.
Do you have any idea about amplifiers suitable for S100?
In fact, there are few Grundig stuff in the market in Taiwan. So I don't
have many opportunities to listen to their production. I have checked
their website recently. It seems they have changed their style. I guess
you would say their best production were all born twenty or thirty years
Thanks for you kind reply.
I know Grundig equipments are hard to find out of Europe. But only
Grundig (and Linear Transfer nowadays) developed and applied the
research to solve the C.C.I. problem (Circuit Chassis Interface).
This is why they sound so different.
Except for Linear Transfer, there is not any other equipment that can
compete with the Grundig integrated amplifiers in production from
1977 to 1986 (V7000, V1700, V20, V30).
The old Grundig went bankrupt in the late '80s. The actual Grundig is
completely different and they have completely lost their knowledge
regarding the C.C.I.
I know the shipment costs are high but you should try a couple source-
amplification Grundig or LT.
I found your website interesting.......what is your opinion of the older
(1950s) Grundig tube amplifiers. I have a large console with a tube amp, Majestic
5-band radio, stereo 2-track open-reel and a top of the line Garrard
The amp has 4 "EL84" output tubes. Are you familiar with this?
Thank you for your response.
P.S. my favorite solid-state amp is the Threshold Class A.
the older Grundig tube amplifiers are good equipments but they can
not really compete with the Grundig amplifiers in production from
1977 to 1986 (V7000, V1700, V20, V30).
Only the Grundig equipments in production from 1977 to 1986 apply the
technical solution of the C.C.I. problem (C.C.I. = Chassis Circuit
The sonic performance of this kind of equipments is far superior to
the older Grundig tube amplifier and any other known hifi equipment.
I really enjoyed reading your recommended
components, and to my surprise, the two speakers you recommended are the
two speakers I own.I guess I wanted to ask your advice :I just changed
from the quad ESL 63 to the DQ10. I also sold my Audio research classic
60,and I'm in the used market for a good used amplifier to drive the DQ10,
and also my ESL 63, in the range of about $750.It can be either solid
state or tubes.(My pre is Conrad Johnson PV11).
It will be great and very appreciative if you
could give me some ideas or recommendations? (I was thinking about Bryston
4B or Conrad Johnson MV50, but I haven't heard any of them).
Looking forward to hear from you.
as you can see in my website, my preferred amplifiers in the used
market are the Grundig V7000 and V1700. I suppose they are really
hard to find in the U.S.A. so I can suggest a new Liner Transfer
amplifier with a CD player Linear Transfer (they work best together). My
second choice would be a Classe' Audio DR3B or Krell KSA50 or Leak
TL12 Point One (as you can see in my recommended page).
Hope this helps.
I'm very satisfied with my new (old) V7000,
even compared to my Sugden A21a (being accustomed to Sugden sound for 25
years, but would like to check whether there are any problems with
mounting of components inside, as you mention in the forum and on the
Italian site. Is there any way to do that check myself, and possibly
I still need Grundig speakers of course to get
the optimal result and have ordered Box 450's, any suggestions on those...
Sorry but I check the v7000
only at my home . If you want shipping to my address, cost of checking
(and correct mounting of
components inside) is 10 euro + shipping cost.
Box 450 is very good , better
I read the Grundig story on your web-site and found it interesting.
I own a Grundig V1700 for about 15 Years an was always satisfied with it.
Unfortunately the left channel of both speakers and headphones broke. Now
I bouht a Grundig V7500 ( I don't have it yet ) and wanted to find out
about that amp. Is it compareable to the V1700, because I think the V7500 was
built a little bit earlier? Or should I try to fix the V1700?
My advice is : try to fix the V1700.
V7500 is good amp but a little bit worse.
Greetings, I have been reading your site and am very
interested in your discoveries and your opinions. I emailed you a few
weeks ago about Grundig amplifiers (I currently have a Naim Nait 2 with
Audiomasters 15ohm Ls3/5a's). I have seen a few V7000 and V1700 sell on
Ebay.de, but I cannot use the amplifiers because they are all set to
European voltage (220-240v) and I am in the USA (110-140v). Is there a
voltage step-down device I can use? Can you recommend another integrated
amplifier that might be available in the USA?
also, I have found lots of old Grundig speakers on Ebay lately for
example these Box 412:
Do they sound good? They look very nice and I am curious how they would
sound on my Naim compared to my ls3/5a's.
I also found this MXV 1000 preamplifier, for 120v:
Is this any good? can it be used with a regular amplifier?
Thank you for your site and all of your insight, which I respect very
much. By the way, I listen to mostly classical piano - and I am also a fan
of Michelangeli - especially his Schumann Carnival and of course, his
Thanks a lot, Jonathan
Box 412 and mxv100 are not a very good Grundig.
For the boxes you can find in ebay de , for amp and preamp the voltage is
a problem ! If available in your country you can use an external
trasformer (input 110v - output 220v)..... or wait to find the amps
Grundig in US ! No other amplifier I can recommended.
Hello, I just wanted to thank you for all the interesting
information on your website. I im looking for an amplifier for my 15ohm
Audiomaster LS3/5a's and wondered what you could recommend? I am using a
Naim Nait 2 right not and i feel they are underpowered. I cannon find any
Grundig amplifier anywhere here in New York. Please let me know of your
You can find a Grundig on ebay (Germany),the
connection with 3/5a 15ohm is very good and much most transparent of the
Naim. I advise the model V7000, V1700, V30, V20 . All excellent.
I have with great interest read your Listening Feeling pages,
and especially your recommendations of old Shure cartridges. I
totally agree, with one important exception. You state that M 75 ED
is a bad cartridge.
Why ? I have many of the old good Shure cartridges (and old
Dual record players, incl. 701 and 1219). In my opinion the Shure M
75 ED is a great tracker, but requires a very light tone arm because
of very high compliance. And I guess you are aware that the new
Shure replacement styli are very bad. You must order NOS Shure
styli from the 1970-80 production (nude diamonds). These are very
difficult to find. Then Shure M 75 ED is perhaps the worlds best
The Shure M75ED is not a bad cartridge but in my
opinion the stylus (original) N75G or N75G T2 is very better !
I guess you are aware that the new Shure replacement styli
must order NOS Shure styli from the 1970-80 production (nude
These are very difficult to find
the same problem... :-)
I have an opportunity in buying an Audio research D70 amp at a very low
price. I was interested in knowing what you think about this amplifier.
Thank you for your time.
The D70 is a storical good Audio Research and if
you can buy it a very low price this is an opportunity (if dont'like it
you can sell everytime). When you have bought the D70 , you can test a old
Grundig amplifier (v7000 , v1700, v20, v30 etc) if you want listen the
difference ! Regards
I have just visited your website and am very interested in Linear
Transfer products because I like Grundig sound. What Linear Transfer
products are supplied to the market and how they can be brought in Hong
The LT production is a little amatorial
production with directly distribution in Italy. The only means for buy LT
is a shipping (expensive) from Italy !
