Soulution 560 D/A-Converter (DAC) with LEEDH

    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 560 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!

    • Features




      In many areas the 560 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 technology, and analogue output stages of top end pre­amplifier quality.



      As with its Series 7 sibling the 560 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 560 D/A-Converter adds a digital volume control that allows direct connec­tion to a power amplifier.



      Audio data is buffered then upsampled to 24Bit/384kHz. 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 560 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 560's 3rd order bessel filter, with a cut-off frequency of 120kHz, 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°, 20Hz - 100kHz! 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.



      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 40 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 560 D/A-Converter has a bandwidth of 20MHz (-3dB). With such speed of response all musical details are reproduced true to life creating a three-dimensional, spatial sound to bring real listening pleasure.



      The 560 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.
