Probably not, but since the computer interface defaults to 32-bit, it is better to use something that actually matches the converter hardware instead of 32-bit... I have not seen clear spec about the conversion section, but I've understood from the posts that it would be 28-bit.

 

You could also try to set the DAC Bits to 20/21 to improve linearity, possibly with noise shaping. I need to run linearity test sweep on the PCM side at some point...

 

I assume if I play everything at DSD512 it doesn't matter what I set DAC bits to?

It is the sweet spot based on my measurements, so yes that's the reason...

 

Interesting.  So in your opinion does DSD256 sound better with this specific DAC than DSD512?
