I was impressed by what I heard and saw from Ideon Audio at the Capital Audiofest, so much so, that I asked for review samples of their Ayazi mk2 DAC and 3R Master Time Black Star USB-reclocker. And here we are.
The Ayazi mk2 DAC is built around an ESS Pro D/A converter with a reclocking Coax S/PDIF input and high speed async dual clock USB audio input. Two CCHD-957 oscillators from Crystek are employed to help reduce jitter and noise below perceptible levels according to the company.
The 3R Master Time Black Star re-clocks the USB signal using ultra-low jitter oscillators, minimizing transmission losses. The USB input offers an optional 5V of power for DACs in need. I am looking forward to getting my ears on both pieces, together and apart. Stay tuned.
