One thing I do notice on some very old CDS from 1983 is a lack of believable
bass. I think this has more to do with using masters tweaked for vinyl
than pre emphasis though.
Certainly modern remastered versions of Abba and Dire Straights originals
sound a lot better than the old ones.

Possibly a dumb question but do any CDs use pre-emphasis?
Possibly some early ones?
And do modern CD/DVD players have the corresponding de-emphasis facility?
I have an old test CD with pre-emphasis on some tracks.
Perhaps I should do some measurements with it.
