my opinion is - after any no-fold (eg, 44.1 - 96) re-discretization sound quality is down.
These DAC's contain 8x (sync, fold) digital filter, that already multiply frequency at 8x.
Yes, digital volume control - way to degrade the resolution on lowest and middle levels.

You can make simple experiment -
on computer with good pro soundcard play test music with 44.1 kHz, resamplinig to 48 / 24bit, 88/ 24, 96 / 24, 192/ 24.
On player with very good re-discretization plugin (foobar + ssrc x), of couse.
If your acoustics/amp or headphones are good, you may hear the difference -
very slight turbidity after no-fold (44 - 96 , 192) increase in the frequency.
And almost nothing after the 44.1 - 88.2.
for the bad records this turbidity can, may be good ... matter of taste. I do not like.
Also pls remember, that even very good delta-sigma DAC's works better on 44/48 kHz, than on 176/192 kHz (see datasheet for pcm1792, for example. and measurements is for 20hz-20khz for all cases)

upsampling supposed to sound better isnt? digital volume tends to degrade the resolution on lowest volumes?
