If you want bitperfect output then yes, you should disable RG and put the output volume to 100%. However, the audible effect of moderate digital level adjustment is arguable and given the very well documented effect of volume on perceived sound quality you may find things sound better properly normalised, particularly if you play mixed tracks from different albums/artists. > in the same tread, I was told that the digital volume for the DIGITAL > output (spdif) also works with 24bits just as at DAC's for the analog > out ? > Yes, the digital output is always 24-bit, and the volume control is done in the 24-bit domain.
