AyaZi D.A.C

The Ayazi was conceived, designed, and sonically fine-tuned by a team of audiophiles and music lovers with professional, engineering knowhow. The aim: bring out the musical magic encoded in the numbers stored within the digital medium, and make it user-friendly and affordable. In other words,to create a device that we,music and audiophiles alike, would wish for.

The Ayazi offers support for up to24-bit/384kHz audio via USB and 24-bit/192kHz over S/PDIF. DSD64 and DSD128  playback capability  is supported via USB (all via on-the-fly software conversion 352.8/24).

Inputs: for the Ayazi S/PDIF input we settled on
a low-jitter re-clocking controller from Wolfson,
which offered us the best sound coupled with
convenience. The USB input is full class-2; to avoid
damage during playback we fortified the input with
our proprietary electrostatic protection, shielding
the Ayazi from electrostatic discharge.
Clock: to further refine the Ayazi’s sonic
performance we selected Crystek’s CCHD-957
HCMOS oscillator. This component sports -100dB/
Hz close-in phase and a noise floor of -169dB.
It matched our circuit design perfectly. Not
surprisingly, the oscillator was designed for audio
to begin with.
Convertion: Unlike many other sigma-delta
implementations, the converters we selected for
the Ayazi incorporate patented time-domain jitter
eliminator technology. This helps to deliver music
free from clock jitter common in digital audio
systems.
Power Supply: It took us a long time to design,
refine and tune the Ayazi power supply. As usual
in such devices, it is not only a matter of providing
power but, especially, of maintaining a very low
noise threshold as well.
