DSD Playback.

A lot of attention was put in providing the highest possible DSD files reproductionby the Ayazi DAC Reference.

Most of today’s DACs, including Ayazi, use multi-bit D/A converters as they provide superior performance than 1-bit converters - even those DAC’s that advertise “native” DSD compatibility. So, the 1-bit DSD stream has – at some point – to be converted to multi-bit for all of those DAC’s.  

Most DAC manufacturers, convert 1-bit DSD to multi-bit within their circuits and “market” DSDreproduction or compatibility in their brochures and actually in their panel displays. We could do the same, and it would be the easiest approach from a marketing standpoint – being also be very simple and low-cost to implement. But with such an approach we would also increase the amount of processing in the DAC, during playback resulting audio quality degradation…

Fortunately, almost all DSD files reproduction using external DACs is done with a computer based music server being the source. If 1-bit DSD to multi-bit conversion is done first in the computer, it can be executed with extremely high precision and superior filtering that actually preserves all of the content of the DSD file. Computer DSD to multi-bit conversion is at least as good as that performed within a DAC, but without adding processing noise near or in the D/A converter chip. At the same time, conversion of DSD to 176.4 kHz, 24 bit AIFF or WAV files can be done ahead of time resulting in no conversion processing occurring during playback! Another big advantage of computer based DSD to PCM conversion is that if superior performance DSD versions such as DSD 4X appear in the future, they can be easily supported with just a software upgrade.

Because of these reasons, Ayazi DAC provides DSD playback capability through a state-of-the-art software application providing either real time conversion of DSD 1X and DSD 2X to 176.4 kHz, 24 bit PCM during playback or, for the highest possible audio fidelity, easy conversion to 176.4 kHz, 24 bit AIFF or WAV files prior to playback.DSD Playback.
