But it really depends on how good the photocopy is, doesn't it?

The issue is what 'poor quality copy' means, and whether that can be
defined in an objective sense. There are bitrates and codecs at which
people will tend to tell copy from original, and bitrates and codecs at
which people will tend to find that difficult if not impossible. That much
we can say. A LAME mp3 at 320 CBR will be very tough to tell from source
on average, for example.

This is quite a heretical claim, to some audiophiles.

I think you're right. Renderining a real acoustic even tin
'stereo'(meaning 2-channel) constitutes a huge spatial information loss.

Yet it can also sound fabulous. The take home here may be that our
hearing is incredibly forgiving.
