Hahaha ... Johan ...
NO.
I'm very sorry, but even with MP3 (where it is the most normal) this will not happen. It will be the complete opposite of "bit perfect".
Btw, never mind the support for MP3 which obviously is not bit perfect by any means, but I have reasons to believe that there too the sound wil degrade to a high degree because of it (normalization).
I understand that with the rough levels the Digital Volume operates, this can be a pain, and even more with UnAttended Playback; In a next version the Volume for UnAttended Playback will be able to change with less hussle though ("a" next, not "the" next).
Concluded, I fully understand your wish, but this time it "can't" be honoured.
