The problem with CDs (and Vinyl for that matter) is balance. Depending on the CD reader, a CD can be rotating at 500rpm. If the CD is not on perfect balance, the vibration not only effects the hardware holding it, but the quality of the data read ie bits can be and are usually misread, requiring high speed corrections on the fly. Only high quality CD readers (and thereby supporting electronics) are successful in this and the reason that they DO sound better.
Vinyl is much the same in that the centre hole is not actually IN the centre of the LP. Having a rare Nakamichi Dragon CT, I can see it correcting the centre with 99.9% of my old and very latest albums.
