My point is, I don't think your CDP has shortcomings. It may not output sound with the characteristics that you would expect from a tubed device, but unless it's seriously a POS, it's reproducing what's on the CD accurately.

A sub would change what you hear more than a CDP--it's adding another driver, and I think we can all agree that speakers make the most difference in the sound your system makes, by a long shot.
