Unitiqute 2 used Naim zero jitter data buffer design?

Posted by: kaydee6 on 15 March 2015

I'm curious about the jitter performance of uq2 and cannot find any information regarding its jitter reduction design especially on the digital/optical input. Anyone has any information to share? Thanks.

I'm wondering too. I can't find any mention of buffering or dejittering regarding the UnitiQute 2 digital inputs.

And if you'll forgive me for slightly expanding the scope of this thread, I'm also wondering about the SuperNait 1 digital inputs.

"Low 100pS antijitter clocking is specifically provided for 32, 44.1, 48,96, and 192 kHz; variable clock rates are phase-locked and de-jittered, so virtually any input will operate the DAC."

But no mention of RAM buffering, a la the NDac, NDS, NDX, ND5XS, etc. I believe there used to be a Naim DAC whitepaper from a few years ago. Unfortunately, I didn't save a copy, and it's no longer in the whitepaper downloads section. I'm wondering if it addressed the SuperNait 1's DAC capabilities. Does anyone have it or know where I can get it?

Regarding the SN DAC, I found these old posts:

I wonder if the UQ2 has some sort of (basic at least) anti-jitter reclocking, but assume, at it's price point, that it does not have RAM buffering. But this is speculation on my part.
