CD Player Suggestions under $ 500


I'm doing little research for my brother.  His old CD player died and he has a budget of $ 500 to replace it.  Any suggestions would be much appreciated.  I think he would prefer new but would consider used.  If the player could play MP3's or stream, that would be great as well.  Thanks.

Discontinued, but if you can find one, an Oppo 103. Class B rated by Stereophile.
Current model is the 203, price is higher, $549.
Very happy with my 103 in my Krell/Vandersteen system...

My Marantz was the first CD player I ever owned that sounded noticeably and immediately smoother and more musical. That's saying a lot for a $600 retail product. Second place definitely goes to NAD, followed close behind by the Yamaha.
