Not entirely true.

Converting to digital can add distortion if the signal level are too high
and the A-D conversion starts to clip.

There are also signal adjustments that are part of the process, like
equalization. You can also have audio compression.


True.

I should have been clearer.

1.  I know that when EAC creates a WAV file from a CD, it is just copying
the bits.  And, it can verify that the bits it read are the right ones - as
you mentioned already.

So far, I am at least 99% sure that this step introduced no changes
whatsoever.

2.  Using Nero to burn the WAV files to a new CD.  Nero could introduce
changes here, like signal adjustments Tom mentioned.  Maybe they are at
different volume levels and Nero automatically did some volume adjustments,
for example.

If anything happened to the quality, it would be during the burning
process.  I am not sure if you can tell Nero to copy the bits and do nothing
else, but that might be worth investigating.

3.  As far as Tom's question as to "lower quality".  I should have asked if
the person was listening to the same track on each CD with the same
equipment at the same general time.  Nothing else would justify any claim to
hearing a difference, IMHO.
