Topic: ADI-2 as standalone DAC
I am using my ADI-2 DAC (the old AK4490 version) as a pure DAC. The reason for this is that I up-sample to DSD256 (ext3 + ec7v2 modulator) in HQPlayer, and I control volume from Roon (which in turn controls volume in HQPlayer). That way I only get DSP and volume changes in one place (Roon does no DSP).
Obviously, I use DirectDSD set to true, and a fixed volume of 0 on the ADI-2, but are there any other settings that are good to set for this scenario? Which ref voltage? The goal is of course maximum SQ, and I obviously don't want any DSP done in the DAC.
