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!
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.

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.
