Hi Andrea, I have a question regarding Vref and the DAC’s output (1.1-1.8Vrms).  Is there an ideal voltage for Vref (best sound, lowest distortion, etc)?  I ask, because I am able to accommodate for variance with my preamp, and now that I am planning, it would be helpful to know that. I won’t be using the buffer, as the input impedance of the preamp is high.

 

 

We have used 4V and 4V7, and in our opinion there wasn’t any SQ difference.
We have powered the DAC Lite with batteries, but it looks like someone preferes shunt regulators.

We will test shunt regulators in the next listening session.
