About product

No deletions at the source are mandatory. This holds even more true for the playback of high resolution files as it did for CDs and SACDs anyhow. No amplifier or loud­speaker can ever make good for what has been lost at the source. The quality of the recording and the signal supplier are of fundamental importance in high fidelity.

The 760 D/A-Converter does excell at exactly this task. It captures all digital music data and transports it in the analog domain. No deletions, no additions!

Highlights

Design
In many areas the 760 D/A-Converter is based on the same proven technical solutions used in the 745 SACD-Player. It also embodies the same principles in its design: top grade digital inter­faces for optimal reception of the music data, a super-precise master clock generator to avoid jitter, intelligent digital signal processing with over­sampling and Zero Phase technology, analogue output stages of top end pre­amplifier quality and a husky power supply.

The 760 D/A-Converter is packed with cutting-edge tech­nology with one objective – the love of music. The parallels include a consistent dual mono design in the output stages and separate power supplies for digital elec­tronics and the analogue stages. The 760 D/A-Converter adds a digital volume control that allows direct connec­tion to a power amplifier.

Oversampling
A powerful SHARC DSP performs the 8 x over­sampling to 24 bit/352.8 kHz or 24 bit/384kHz, depending on the digital input signa,l with the utmost precision. We believe precision of inter­polation is more impor­tant than high clock rates. Our players and D/A converters use an algorithm from the highly regarded Anagram Technologies followed by Burr Brown D/A converters in a digital symmetric configuration. As we consider the PCM conversion technology as superior, the DSD signals get converted before its final D/A conversion.

zeroφtech
The 760 D/A-Converter is equipped with soulution’s innovative Zero-Phase-Technology. Smallest timing errors provoked by the analog low pass filter of the D/A converter get eliminated. Every D/A converter requires an analog low pass filter in its output in order to suppress high frequency noise and aliasing signals. The 760’s 3rd order bessel filter, with a cut-off frequency of 120 kHz, does show a phase shift of up to 15° in the audio band. Due to the Zero-Phase-Technology the phase error of the analog music signal remains below 1°, 20 Hz – 100 kHz! The Zero-Phase-Technology brings you even closer to the beauty of the source material! The music gets even more realistic and 3-dimensional with a lot of “air” around instruments and voices. As close to the source as possible! No detail gets lost.

Clock
Utmost precision of the clock signal is a must have for a top class D/A-Conversion. Lowest phase-noise behaviour is by far more important than long term frequency stability. Together with experts for highend oscillators we did develop a TCXO which is optimized for this application. It does not run on its first harmonic but on its 3rd overtone. The clock modules work at frequencies around 100MHz, this re-quires extremely fast amplifier stages within the oscillator loop but allows achieving best results regarding phase-noise. Even the best OCXOs or rubidium based oscillators are not able to outperform these specifications. The 760 DAC does have a spate oscillator module for signals based on 44.1 kHz and signals based on 48 kHz. With the synchronisation to an external clock signal the performance of these oscillator modules would be deteriorated. Therefore the 760 does not provide a clock-input. However, external components can be synchronised to the 760 D/A-converters high quality clock signal through its clock-output.

D/A conversion
Burr-Brown devices perform D/A conversion only. Their internal upsampling and filter stages are not used. The output currents are converted to voltage and then filtered. With an internal bandwidth of 80 MHz, this current/voltage conversion stage allows best signal-to-noise performance and maximum dynamics in the analogue domain.

Output stage
The wideband output stage of the 760 D/A-Converter, which is based on an optimised circuitry with special power transistors which are further linearized by an analogue computing network, has a bandwidth of 40 MHz (- 3 dB). With such speed of response all musical details are reproduced true to life creating a three-dimensional, spatial sound to bring real listening pleasure.

Power supply
Key to any good sounding audio source component is a stable, noise-free power supply – especially for the audio stages. The 760 is equipped with two dedicated power supplies: one for the audio stages and one for the digital circuits. For powering the audio stages an innovative, amplifier-like circuit design is used, providing an extremely stable supply voltage. With more than 500,000 µFarad of storage capacitance it provides almost unlimited impulse current for the analog circuits. Bus bars supply this power throughout the 760 D/A converter without any losses. A unique concept in the audio world!

Operation
The 760 D/A converter is operated from front-panel buttons and a rotary control. Further functions can be used to optimise and match an entire audio system around different components.

About brand

Soulution


Soulution is owned by the Spemot corporation, a company located in the Swiss town of Dulliken. Spemot is a well-established designer and producer of electronic devices and electric motors used in automotive and other applications including professional catering equipment. The company has a strong track record in innovative bespoke solutions that meet specific customer needs.

The soulution brand for premium audio was created by Spemot’s two managing directors Cyrill Hammer and Roland Manz, both of them passionate high-end audio hobbyists. The pair are long-time Swiss distributors of the Hi-Fi & Records magazine. Having owned and heard top amplifiers produced by US and Japanese manufacturers, they resolved to lay down a challenge and build a family of audio products that would set a new and even higher benchmark.

As reviews of soulution products by audio magazines around the world testify, Hammer and Manz have achieved their goal.

Design

The outstanding sound qualities of the soulution products should also be supported by the design of housing, both visually and by their construction. Due to their size it was clear that they must integrate optimally into a listening/living room to be enjoyed not just for their sonic beauty but as well for their visual appearance. The development of the housing design was therefore carried out with the same care and professionalism as the development of the electronics. Several proposals were made which fulfilled both the technical requirements for stability and heat dissipation, as well as the design requirements.

Design Awards

The effort has paid off. The soulution products were awarded several times for its timeless and elegant design by international design juries.
