Interesting anecdote: I had an Aiwa bookshelf
system set up in the store and playing a Stevie
Wonder CD. A guy came over and started playing
with it, listening to different tracks etc. He said it
sounded great, and he bought it.


Next day, he came in, saying he had the "same
disc" at home, but that the system did not sound
nearly as good as when he played with it in the
store. Since he said he had the disc, I asked him
to bring his in next time he visited.


The next week he came in with the CD, and I
compared it to the copy in my inventory: His was
a REMASTER....

And, some remasters are dreadful. Not infrequently the remastering
engineer has been of the "louder is better" school, and the remastered
disc suffers from serious signal compression and (more than
occasionally) actual clipping. The dynamic range of the remaster is
often poorer than that of the original CD.

The spectral balance will also often be "played with".
