I have had my share of bad-sounding cd's and "some" vinyl as well. But thanks to my superior brain (Ha Ha), I don't "hear" bad stuff any more (with some truly horrible exceptions of course). What I mean is just that I can enjoy the music coming out of my Tivoli Radio or a pair of HT JBL's. The scratches on records also don't bother me much. Anyone with a collection of Charlie Parker albums is either going to concentrate on his gift or go crazy wishing he hadn't died so young. I guess I'm half-audiophile and half- Stack some 45's on my ancient old RCA record player and wonder how music comes out of it at all.

All of us have had to come to grips with bad sounding recordings. They can be disabling and make you question your whole system. The trick is to accept them for what they are and not to generalize. I try to listen for the music and skim over the imperfections. When confronted with a clinker, to save my sanity, I play a recording i know to be superior sounding. That restores my faith in the system and brings me back to reality.
