Hi,
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,

Gauthier

hallo.
what is linear transfer mod? is it possible for a philips cd 650?
i found your webpage through google images search for grundig cd7550.
i am offered this cd player with no oversampling mod and a lot of upgraded components. have you experience with no oversapling for the grundig?
i have a philips cd 650 and very much like the sound. it is modified with no oversamoling and other components. i like it better than a no oversampling modified sony 227esd. and it plays in a different world than battery powered monica usb dac. my amplifier is luxman l-410.
speakers teufel m200. i like my stereo setupvery much so far but my one concern is the digital playback. good vinyl lps on a rega p2 with soundsmith smmc4 cart sounds nicer and realer or alive...than cd.
can you offer a cd960 with LT mod?
best regards and greetings from berlin.

Hello Leonard

Massimo Ambrosini

Hi!
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 substitute 250box.
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 V1700.
So far, I like what I hear from Sanyo JA220, altough it's connected to some small Nordmende plastic speakers (it's the only one I have that are 8 ohm).
Thank you for sharing your knowledge of super super Grundig products.

Best regards
Kresimir Hxxxx

Hi Kresimir
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 tampered

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

Thank for your beautiful e-mail. I am happy that you have appreciate my work.

Dear Massimo,

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 alive.

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 working condition.

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.

Best Regards,
Michael

Dear Sir

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

Cesar
 

Dear Cesar

I can check your v7500 for a cost of 70euro+ shipping cost. For room very large of 80mq is indicated a box2500a near to rear wall.

Dear Sir,
 
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.
 
Best regards
Mirek xxxxxxx
 
PS. You know any possibility to buy original loudspeakers for Grundig Aktive-Boxes?

Dear Massimo!
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 .
 
Dear Pawel
Thank You!
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 vacations!!
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 words...

Massimo

All Grundig cables are the better cables (it's incredible but true...)
I will happy to read your post on forum :-)

Hi Kiran
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.

Hello Massimo,

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 stylus.
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.

Best wishes!

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:

Dear Massimo,

 

Good day,

How have you been?

 

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.

 

 

Take care,

Robert

 

 Hi Robert
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.
Best Regards
Massimo
 

hello

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
gugsi

Hello

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.
 
Regards
Massimo

hello massimo
thank you for your answer
its very expensive..... but interessting.....
i will test for the first... the non oversampling, its easy to do.....
nice evening
greetings gugsi

The zero oversampling is very different sound of CCI sound, I don't advice zero oversampling if you love the music feeling.
Regards
Massimo

hello & good morning

i think about that converter
http://www.net-audio.co.uk/tda1541nos.html
its cheap and i can build it back to the original every time
do you know the converter??
greetings gugsi

Hi Gugsi
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: marcoamboldi@libero.it
Regards
Massimo

ciao massimo

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
gugsi

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

Regards
Massimo

i think the cd7550 is the same like my philips cd304??
CCI .... can you tell me more about this??

greetings gugsi
 

Hi there,

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

Kind Regards

John

Hello,

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
Screen TV.
Regards
Massimo

Would DSL speakers play good with grundig amps?
 
Dear Pawel
Yes, this is possible if you haven't a large room.
 
My question is: would it be smart to buy speakers only at the beginning and then move to M50?
 
Yes.
 
Regards! I hope I can join one of the meetings next year! Pawel.

Hello Massimo,

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?

Thanks,
JJ

Dear Jioe
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.
Regards
Massimo

Dear Massimo,

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.

Best Regards,
Predrag

>Dear Massimo,
>
>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.

Dear Sirs,

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!
Best regards!

Bora
Dear Bora
You can find v7000 on ebay.de I can sell one of mine v7000 (checked for CCI implementation) but is over ebay price.
Best Regards
Massimo 

hi Dear

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)

Dear Dusan

if your local Grundig service is going to service your CD7550 please be sure that disassembling and re-assembling will be done exactly

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.

Dear Mirce
I have cd30 Grundig in room of my child and is the first CCI cd player...but not full CCI.
Cd7500 is a circuit clone of cd73/cd303 but NOT is a clone for CCI implementation only present in Grundig models.

If you listen them there are not a little differences with Philips/Marantz clone...

Dear Dragan
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.

Massimo

Hi Dragan

Dear Massimo!

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 YOU!.

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.

Dear Pawel
How are you?

>But one day
>I will visit you in person and will get some of your amps and speakers.

I hope here soon :-)

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.

>1) What's the tracking force of old but not original needle? I know

Hi Jae
Tracking
force is the same (0,75gr) for better sonic result.
You can increase to 1gr or 1,25gr for better tracking but with a worse of sound

Dear Sir,

Searching on the net I found your wonderful website and I really amazed.

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 I am using the same Philips CD 960 now as you do, but without modification. I think there are more possibility in this player, 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 sound.
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.
Yours sincerely,
Tamás


Dear Tamas
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”.

Best Regards
Massimo

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?

Best regards
Adrian xxxxxxx

Hello Adrian,

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.

Regards
Massimo
 

>Hello Massimo, could you tell me what are the differences between 1rst

Yes
There are exactly three version of B&W DM6 The first with woofer control level, wood front panel and all yellow midrange.
Second version
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
many differences......

>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...

If you
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).....

>Fred,

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 Cornwall I.

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!

Fred,

Hello
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...
Regards
Massimo

-----------

Hello Massimo and thank you very much for responding!...

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 box2500a,box1500a,box850?

Bass reflex supply a different kind of sound in middle-bass frequency : more empty

Massimo

Thank you so much for helping me...

Have a good day!

For place

The solution MA50+xv7500 or integrated MA10 have the advantage of more linearity due to absence of tone control. You can see the "technical test" on my website:

No advantage in CCI implementation (same level).

Dear Pawel
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....

Hello James
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.

>The sound is really fantastic.

I think also :-)

Hello Sebastian
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.

Hi Massimo..

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 on. 

Thanks for your concern..

Hello Artur,
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 solutions.

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.

Hi Dragan,

I am happy you have found a CD7550 in very good conditions.
It is
very rare. For interconnect cable you can look for SCHWAIGER TFS
2052
or old Grundig.

R7200 and V7150 are quite similar in sound quality. If you find in good conditions and low price, you can choose one of them waiting for one of the suggested.

Dear Michael
To never believe (forums,reviews, etc...) but always to listen with the own ear!
I advice to sell dq30 ( the worse Dahlquist that I have listened) and to render non-mirror one of your DQ10. Then you can find a Grundig CCI amplifier and a Grundig CCI cd player (see my website) and live happy!

Massimo

Dear Pawel
If you buy a pair of box850a
or 1500a with 36cm (h) stand and drive them with a full CCI Grundig...
you don't reconnect the B&W... :-)

>I also want to ask if you are
still able to supply interconnects and one of the recommended turntables? If this is possible we can discus details later. Regards Pawel!!

Of Grundig productions I can supply only the turntables PS1010/1020 and the preamplifier XV7500 both checked for CCI implementation.
I can supply also interconnected cables enough equivalent to Grundig cables.
On turntables the cable is standard included .

Hi,

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.

>Robert

Dear Robert
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 ways.

Best Regards
Massimo

Dear Massimo,

with interest 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)?

Kind regards, Michael

Dear Michael

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 mod.(CCI updated).

>Dear Massimo,

Dear Robert

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... :-)

Yes, but have you a turntable ? If yes I advice XV7500+MA50, if no I advice integrated MA10 ( without phono)

>By the way, what's different between MA10 with v7000/v1700/v35(I have one
>for Box350)

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 musical istruments.

Best Regards
Massimo

Hello Ritchie,

thanks for your e-mail. The 5000 series is not so good as the best

Grundig (full CCI) amplifiers (V7000, V1700, V20, V30, V35).

Dear Massimo,

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?

Best Regards,

Robert

Dear Robert,

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.

Listening 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.

Best Regards

Massimo

Dear Massimo,

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?

Best Regards,
Robert

Hallo Massimo,Jon writing from Bath in England.My home system is a pair of IMF tls50mk2 speakers driven by the Beard ca35 and p35 pre-power combination,not very Grundig but pleasant listening.The music sounds fabulous but the moments between tracks and the hush at the end of an album are marred by the humming from the p35's transformers ,can you help me with some advice on this matter please,I notice you have reviewed this amp in the past.Yours,Jon

Hi,
I'm sorry but I can't help you with your humming problem. You could try to replace your combination with a Grundig V7000/V1700 and CD7500... ;-)
Regards

Massimo

Dear Sir:
Sorry to disturb you, I have the opportunity to own a Grundig Super Hifi Box 450.
But i can`t find any information on the internet.Could you tell some information for me? And your commends. Thanks a lot.

Best wish
cinderella

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 and source.
Regards
Massimo

Hi there,

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.

Best regards,
Emir

Dear Emir,

I am sorry but the LT modification is a proprietary technology. It is
exclusively applied in my laboratory and the price is XXX eur
excluding shipment.

Regards

Massimo

Dear Massimo,

Sorry for the late reply as I just came back from a seminar conference
overseas.

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???
:-)

Best regards,

Handoko

Dear Handoko,

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 have different
distances in emission centers.

Best Regards
Massimo
 

Dear
Massimo,
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.
Best regards,
Grzegorz xxxxx

Dear Grzegorz,
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.

Best regards
Massimo
 

Dear Massimo,

Thank you very much for your answer.

So I would better look for older models.

I have a few questions, because there are a lot of Box's models and I do

not know yet the hierarchy between them.

The best series is HiFi Box 300/400/500 & 350 (or it is called

Compact-Box 350?)?

Is the series Super HiFi x50 almost as good as the older ones? What

about speakers from this series, but called "Professional" - are they

better than the normal ones?

I also found Compact-Box series (e.g. 350a, 353) and HiFi-Box xx3

Compact (e.g. 403,313) - how are they?

For my room (9m^2, speakers will be on a bookshelf), what models should

I look for: from 3xx to 5xx? Or 5xx would not be appropriate (e.g. too

big)?

I understand and have respect to the fact that the Grundig chain gives

the best best results. However, nowadays I cannot change my audio

components (maybe in future when I get involved in the Grundig passion

:-) ).

Sorry for disturbing you with my boring questions.

Best regards,

Grzegorz  xxxxxxx

Dear Grzegorz,

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.
Best Regards

Massimo

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.

Regards
Brian

Dear Brian
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!

Dear Sir,
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.
Sincerely yours
RAdan xxxx
 

Dear Radan
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 :-)
Best Regards
Massimo

Dear Massimo,
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.
Best regards
RAdan

Dear Radan
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.

Best Regards
Massimo
 

Dear Massimo,

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

audiophiles 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.

Bravo Massimo!

Warmest Regards,

Handoko

Dear Handoko,

Thanks for your kind comment !

I am very happy to know you appreciate my effort to give you the best result today in musical reproduction.

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 user manual)

Best Regards

Massimo

Dear Massimo, 

Thank you for your kind reply.

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?

Please advise.To 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 keep 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! 

Best wishes,

Handoko

Dear Handoko,
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.

Best regards
Massimo

Dear Massimo,

For your information, I did not change the original cartridge on the PS1010 which you supplied. I leave

it as original to maintain a genuine performance by LT standard.

The PS1010 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.

.......

Best Regards

Handoko

Dear Massimo,

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 and CD7500.

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 Quad speakers!

Thank you very much for your kind help & assistance.

Best wishes,

Handoko

Dear Handoko,

thanks for your e-mail. I am glad to know you are well.

Best regards

Massimo

Dear Massimo,
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. Please confirm.

Handoko xxxxxxx

Dear Handoko,
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.

Best regards
Massimo

Dear Michael,

thanks for your comments.

In order to the reach the best performances, the LT amplifier has to

be matched only with LT or some Grundig components. The reason is

that they are the only hifi equipments featuring CCI technology.

If you connect a standard CD player or phono stage to the LT

amplifier, the result is not optimal.

You should use only a CD player LT mod. or Grundig CD7500-7550 for

best performances. If you are interested, I can supply them.

In case you want to upgrade your LT MA10 50W and add the phono stage,

you 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.

Your 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)!

I can also supply the PS1010-PS1020 with original stylus Shure n75gt2 NOS(New Old Stock).

Best regards

Massimo

Dear Massimo,

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.

Take care!
Robert

Dear Robert,

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. :-)

Massimo

i vostri articoli e che so che il Grundig ?buon prodotto. Ho chiesto alla
mia sorella lo aiuto ho comprato un V7000 dall'ultimo mese tedesco. Ora
godo la musica. Progetto desidero comprare 7550 e 7500, ma ora sono molto
costoso. Ho letto oggi la vostra lettera ed ho trovato che avete accennato
cd35. Sembra pi?poco costoso di 7500 e 7550. Se ?scelta accettabile, sto

Dear Robert

Cd35 is equivalent to cd7500 and cd7550 for CCI implementation. If you would have some other advise for Grundig you can join to mailing list: http://groups.yahoo.com/group/Grundig_LT_friends_intl/

Dear Massimo,

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
Loudspeaker: 3.

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.

Best regards,
Kwang

Dear Kwang,

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.

Massimo

Hello Massimo,

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 better Grundig. 

Regards

Massimo Ambrosini

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 frequency reading.

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 ?) ?

Regards

Kjell xxxxx,
NORWAY

Hello Kjell
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 frequency stability).

Best Regards
Massimo

Hello Massimo
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 changing the
preamps for the most modern XV 7500 or there is small difference between them?
Box M300 + receiver MR200-2 is also astounding. What´s your opinion?
Best regards from Spain
Lorenzo xxxxx
 

Hello Lorenzo

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
outstanding.

Saludos
 

Hello,

Can you send me more information about the upgrade ?

Thanks Johan xxxxxx

Dear Johan

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.

Best regards

Massimo Ambrosini

Hi, 

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? 

Best regards. 

Bostjan from Slovenia

Dear Bostjan,

as you can see in my website, my CD960 modification 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. You should also try a pair of Grundig Boxes following the indications at my website:

http://motxam.interfree.it/Ainstallation.html

The cost of modification for CD960 is 500euro but I can't suggest you this way if the rest of your hifi system affects the performance of the CD960 modified.

Best regards

Massimo

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

Hi

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.

Best regards

Massimo Ambrosini

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 Massimo!!!! 

Best regards.Elli

Dear Kwang,
 

looking at 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 wall).
- 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.

Best regards
Massimo Ambrosini

 

>Is felt foot not original one ?

I don’t know, but no felt foot is the better solution. :-)

Best Regards
 

Dear  Kwang 

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.

Hello!

I´m a Grundig Fan too !

Do you need some pix of a Monolith Soundwall 190.

I´m the proud Owner !

Kindly Regards

Mike

Hello Mike,

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. :-)

Regards
Massimo

Hello!

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.

Thanx Mike

Hello Mike,

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:

Preamplifier XV7500
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.

Best Regards
Massimo

Hello!
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 !

Ciao
Mike

Hi,
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.

Mike

>Price is about 50 euro.

A great tuner for a little price…..:-)

Hello,

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 better.
A lot of thanks for your answer.
Best regards
Horst

Hello Horst,

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

Regards

Massimo

Hello Massimo, 
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
Horst

Hello Horst,
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 !

Regards

Massimo

Hello Massimo,

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?

Best regards 
Horst

> Me would interest still, from where your interest and competence for

Dear Horst,

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 SL1000,
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.-.

Also the famous Rogers LS3/5a 15ohm were priced 175 EUR in 78-79 and nowadays their quotation
is 800-900 EUR!

Dear Sir,

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

completes the music sources. The amp is a stereo ML23.5. All the wires are NBS Signature and

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,

hi,

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

Best Regards

Jacek

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 :)

Best regards

Dear Andy,

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...

Best Regards
Massimo

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

Regards

Dave

Hi Dave,

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:

http://motxam.interfree.it/Arecom.html

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.

Grazi, Josh

Hello Josh,

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)
Best Regards

Massimo

Hallo Massimo,

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 such cables?

Mit freundlichen Grüßen,

Michael M.

Vienna

Dear Michael,
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):

http://motxam.interfree.it/Atop.html

In case you are not able to build cables, I can supply them (with DIN plugs) and the
cost is 4 euro per meter excluding shipment.

Hello Massimo,

How do you think about Grundig preamp SXV6000 ?

Best regards,
Kwang

Can you post the question on new mailing list ?

http://groups.yahoo.com/group/Grundig_LT_friends_intl/

I answer to you on mailing list.

Thank you

Massimo

Dear Massimo,

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 the
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 audio devices.

Best regards,
Kwang

Dear Kwang,
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
quantity).

Best Regards
Massimo

Dear Stefan,

my name is Massimo Ambrosini.

The C.C.I. problem can affect active components (amplifier, preamplifier, source) and also passive components (speaker, cable). I am sorry but I do not intend to explain what it does concern.

Please, refer to my website and other letters

Hello Peter,

the LT-mod for CD960 involves the solution of the C.C.I. (Circuit Chassis Interface) problem.

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

technical explanation except of what you can read in my website.

I am really sorry.

Best regards

Massimo

Hi,
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.

Kind regards,

André xxxxxx
The Netherlands

Dear Andre',
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 really sorry.

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 any answer.

The C.C.I. can also explain why cables sound different...

Best regards
Massimo

Hello Massimo

I find your website very interesting.

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.

Lorenzo xxxxxx

Dear Lorenzo,
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

Massimo

Dear Göran,

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

its sound.

100 Euro for a Philips CD960 is a good price but the LT modification

is quite expensive (500euro).

Hope this helps.

Massimo

Dear Göran,

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.

Hi Massimo,

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.

Best,
Ludwig
 

Dear Ludwig

I am happy you have found a Grundig speaker in Taiwan. As you can see

in my website, the 660a is just a bit worse than the 650a:

http://motxam.interfree.it/Atop.html

As already told you, the old Grundig went bankrupt in the late

'80s.The 650a, 660a and others speakers are out of production. In

Europe the Ebay quotation for these kind of speakers is 100 - 150

Euro.

Please, remember to match the Grundig speaker with Grundig (or LT)

amplifier and source to enjoy its sound.

Best Regards

Massimo

Hi Massimo.
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

Dear Elli,

I've never listed the Dynaco in my recommended page.

You will find my favourites equipments at: http://motxam.interfree.it/Atop.html

You will find my recommended (second choice) at: http://motxam.interfree.it/Arecom.html
