That is my projects on original design, some of whom were born CCI and others (older) born with
traditional frame and then updated CCI. The first version of the MA100 which was adopted in 1984 was zero feedback - Class A.
... since then many things have changed, now is very different chassis as well as with feedback and working in class AB. I
enjoy as a manufacturer to make a few copies of my items for those who appreciate having them want. The advice that I'll never
stop giving is: to do a direct comparison with your electronics, only then will appreciate clearly the differences.

Some pictures of Linear Transfer MA100 mono.
A 100W 8ohm capable of delivering 400W into 2 ohms compared to stabilized power supplies of power. Use no wiring and is
being updated based on the knowledge acquired on the CCI over the years.
Even at this early version of the amplifier was no cover rigidly attached: provided the only cover was a Plexiglas lid
that served only as a dust cover was removed and listening phase. Although updated CCI was not possible (given the
particularities of this frame made of all solid aluminum bars) assembly of the lid so that it remains the only full CCI LT
to listen without cover. The sight inside I still believe will satisfy even fans of aesthetics.
Optimized CCI on the soft.

LINEAR TRANSFER MA200 was born on a bold exercise with the aim of
maintaining the sonic characteristics of MA100 mono, but in a final position to provide 1.6 KW per channel into 1ohm!
TO3 transistors in a container 64 in total (including 16 employed in the two supplies stabilized power) for a final stereo
deck packed with features, as well as size and weight, not indifferent. Special circuitry uses patented two-stage time .
The photo shows only half of the amplifier: two identical cards are mounted on the bottom of the cooling tunnel.

CCI mod CD players.
Coinciding exit of Philips cd960 born also my first approach to the modification of CCI CD players. The first version of the
amendment results in the absence of the cover (as opposed to the current one when the cover is clearly present).
We only need a listening comparison between this (or any other) cd player and the modified version to convince anyone of the effectiveness of the intervention, both the Irrelevance of the type of conversion and mechanical use: Once you
have changed all the machines ( if editable means ...) sound almost indistinguishable from each other, whether the Roadstar
cd960 or DVD from 20euro ... provided they have adequate linearity of frequency response.
A similar and equally excellent performances are also three cd Grundig serial all developed with ICC criteria: the cd7500,
cd7550 and cd35 unfortunately no remote.
The development of the CCI player allows us to understand how the limits may relate to digital are in fact attributable to
another: the equivalence is remarkable compared to analog.

1988
The year of birth of the MA25 and the MA50.
Two final stereo from the same circuitry that enclose the experience acquired in previous finals on the CCI (see
uncomfortable truths). A 25watt and a 50Watt into 8 ohms, which also easily drive 2ohm loads.
The results obtained from these end-if combined with a MA10P or a Grundig XV7500 (ie a full pre CCI) of the integrated
MA10 is potentially the same but with the advantage of being able to put an end to the ground and close to the speakers
with the highest reducing the length of power cables.

Preamplifier MA10P same characteristics of the integrated musical in a pre MA10 alone MM phono + 2 line inputs. Aesthetic
integrity MA10 identical except for the lack of rear heatsink.
Alternatives to this phono preamp you have full CCI Grundig XV7500 well with it full CCI.

1993
Experience in understanding the behavior of the phenomena of high frequency
radiation and the integration of this with the knowledge gained from Grundig products leading to the emergence
of the integrated MA10.
MA10 consists of a pre-integrated MM phono + 2 line inputs and a stereo amplifier 50Watt into 8 ohms (or 25watt
into MA10s).
Built also without the phono.

CCI mod. of aktiv 20-30-40-50.
Web development made it easier to find with these active speakers Grundig great potentials to be exploited, unfortunately,
only limited action CCI that had never been optimized at this place was the first set of active speakers. Not by chance is
the only product that I decided to change Grundig CCI
The difference between the amended and that number is
what goes around listening between a V1000 and v7000 .... evaluates each with their own ears.
Remain unchanged the crossover frequencies and levels sent to each speaker.
Of the four models produced the only one that has potentially a little less and the 50 (which by the way went into
production at a later date with respect to 20-30-40) even having exactly the same speakers and the same electronic 40 does
have a gap in the provision vertical alignment of speakers (which, however, started to go to fashion ...).
The three top models (20-30-40) gives a similar sound, but in rooms of different sizes (see "installation speakers")

And so to DSL (Dynamic Loudspeaker System) result of 8 years of work (the project started in 93). The conditions for the
project had a very ambitious goal: to keep as much as possible the definition consistency and transparency typical of
Grundig box300 but with an extension on the lower top. Perhaps if I had decided to climb Mount Everest I would have less
problems! From the start the difficulties proved to be enormous and the evolution of the case has been somewhat tortured (including
studies on the acoustics of the room, interference between the speakers and the different types of crossover) but as if a
drop of water which continues to fall can penetrate the concrete, so I think if you have the sufficient dedication and
there is discouraged or sooner or later get the results.
