Oak, if what you mean is that you're presently using a CD/DVD player to play 2-channel music CDs and you think that a separate CD player would significantly improve the situation, it's highly unlikely. Recent CD/DVD players have lasers optimized for the two functions. If you want a multi-disc CD or CD/DVD player as a matter of convenience, that's another matter, but don't expect audibly improved sound.

Enjoy the music, not the equipment.
