Nope, the phase response of common FIR filters, such as those found in sigm=
a-delta A/D converters is linear (assuming their coeffients are set accordi=
ngly).

When you set the sample rate to 22.05 kHz (which I believe nobody really do=
es in practise), then you will of course hear the low-pass filter effect! I=
n addition to that, you may hear aliasing effects because the steepness of =
LPF is limited. But this is not going to be an issue at 44.1 or at least at=
48 kHz.
So, please stop confusing us!
