I can't give the exact specs, better asking on a Playsation fourm, but I know they are pretty good. I'm a bit of a Hifi Fanatic, and it's got the Sonys CD system in it, delivering a really good sound. Not distorted, and it doesn't mess up or treble or bass. Obviously it's not designed for a CD Player, so if you went and bought a really expensive (and a good) CD Player it will be better, but it does stand up to some pretty expensive ones. An idea might be to buy "What Hi-Fi" if you're looking for a stand alone CD Player.
