I highly doubt that it's anything related to absolute polarity, as Casouza suggested. About 50 percent of recordings are made out of phase anyway and the effects, to me, do not seem to be related to tempo problems.
I'm thinking the CD player too. Ad Viridian said, try another CD player, or some other sources and see if that makes things better. Usually amps and preamps can sound poor and distorted, but not like they're playing at slow speed.
