soulution
nature of soundTo preserve the natural purity of sound in all its facets – this is the challenge
first-class audio components should be able to master.

Music is a sensual, emotional experience and needs no artificial enrichment.
It should pass through each component in the audio chain with as little adulteration as possible.

The aim of the designer should always be: Omit nothing, add nothing.

At soulution we use technology to serve that ideal. Our audio components
deliver natural music. Interfering as little as possible with the sound picture.
Serving the music, rather than imposing upon it. Achieving complete control
without losing the magic.

Technology as the servant of music, not its master. That’s what we atsoulution mean by the “nature of sound”.

For optimal sound absolutely nothing should be lostfrom the source. This is as true for the reproduction ofhigh resolution files as it is for playing other audio
formats. No amplifier or loudspeaker can replace what
is lost. This is why the quality of the recording andplayback components is so crucial. The 760 D/A
converter meets this goal brilliantly: transporting all
the musical information from the digital into the analog
world, omitting nothing, adding nothing.

The perfectly coordinated interaction of the analog
and digital stages ensures that nothing gets lost at thedigital source. This is achieved by using first classinterfaces for the optimal reception of digital data, ahigh-precision master clock generator which does notallow jitter, intelligent digital signal processing withoversampling and zero␸tech, analog output stages in

Ultra-precise clock signals
An extremely accurate and clean clock signal is fundamental to a perfect D/A conversion. Minimal phasenoise is more important than the long-term stability of
the clock frequency. To meet the standards requiredby our D/A converters, experts in the field of oscillator
design have developed optimised crystal oscillatorswith minimal phase noise exclusively for soulution.
Synchronous processing of the digital data along its
entire signal path ensures optimal results and isachieved by using two clock modules at 22 and 24 MHz
respectively.

Records are making an incredible comeback. Declared
dead 20 years ago, today vinyl is attracting an evergrowing fan base.

When playing records, the phono stage is almost
always the limiting component in the system. Compromise at this point profoundly impacts on sound quality.
The technical demands are acute. A phono amplifiermust deliver a gain of up to 80 dB (which equals anamplification factor of 10,000) while remaining linear
and preserving true phase. At the same time it must
provide equalisation in accordance with RIAA-IEC
standards.

The duties of a preamplifier have changed considerably over time. Analog turntables with MC cartridges
require preamplification of around 60 dB while D/Aconverters or CD players provide output levels that candrive power amplifiers directly. That notwithstanding,the preamplifier remains the central switching andcontrol unit, the real heart of the hi-fi system. Our
research has also shown that the preamplifier is
irreplaceable for sonic reasons.
