The goal of high quality volume control is to make the noise inaudible. ESS has an interesting presentation on how their on-chip digital volume control works.

If you use both an upstream digital volume control for example moOde's Software or Hardware volume control, and a downstream analog or digital volume control you should calibrate the entire system for lowest noise when attenuating volume.
1) Set downstream analog or digital volume control to 0 (no volume output)
2) Set moOde volume to 100%
3) Play a track that represents music that you typically listen to
4) Raise the downstream analog volume to the loudest level you would ever listen at
This generally results in a configuration where noise is inaudible when attenuating volume.
Hi Tim
Yes I agree with your method and it's what I recommend to others. However tracks have different playback levels and using
Moode's volume control remotely is more handy than operating the downstream analogue volume control.
Over time and with frequent use, there's a possibility that less discerning users will overuse software attenuation, hence the suggestion to have a user preset limit.
Hi,
The downstream volume control is not used after the system is calibrated. Volume is controlled entirely by the upstream control i.e., moOde.
