Which Sony dvd playr is a good CD playr

I concur with the S9000ES. The 7000 and 7700 have a decent CD sound, but they're a step below the 9000. From there, the step falls rapidly.

Proacman, audio is important for DVD-V too--be it listening to movies or concert videos. I can tell the difference in between my Sony DVP-300 (which cost me $500 2 years ago) and my S9000ES. Most noticable is the bass, but the 9000 is more dynamic and clean. Listening to Hell Freezes Over, James Taylor, and Fleetwood Macs' The Dance was a new experience. I won't recommend a cheap DVD player to anyone who cares about audio.
