I remember early on learning just how poor CD transfers could be when I picked up this album called Expansions by pianist McCoy Tyner. The kind of music on that album is right up my alley, but the sound quality of the CD I got, which is on some kind of obscure reissue label, isn't just bad, but terrible! I've never heard any other version of that album, but I would bet my life that the recording quality of the original of that sounds far better. I need to pick up another different version of that album, either on CD or LP. Still, I would say that this kind of thing is far more the exception than the rule and that most CDs I have, particularly jazz ones, sound great on that format. Some that are remastered, or even remixed, sound better than the original LPs...
