If there was any difference between two digital copies (with no analogue
stage) then high end rolloff is impossible. Random bit errors (which is
what we are dealing with) could not possibly produce this result.
Why not sample the copy into a computer and use Cooledit (freeware) to
perform a harmonic analysis ?

Unless there is an analogue stage, it isn't possible for these kinds of
artifacts to be introduced by copying a CD to another CD.
