If that (whatever "that" is, I'm not sure I follow your argument) is the
case, then it should show up digitally, too.  If the digital signals
are no longer in the right time relationship with one another, that's
a problem, and should be digitally detectable.

I still claim that if the digital signals are really the same
(including their time relationship), then any sonic difference
must not be in the recording meduim.  If they're not the same,
then there's a bug in the copy process.
