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.

I have been using the Marantz cd 6006 for a few years now and no complaints it has never failed me. However members here pointed out it is the weak link in my system and should be upscaled. My system sounds real nice with this CD player. As a 78 yr old with hearing issues I doubt an upgrade would be noticeable for me.  

Sony had some universal players in the $400 range but the weak point was the DAC.  If you have an external DAC you like then it would add SACD and Blu Ray to the party 

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.

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...

I would also consider Cambridge. The build quality is very high. If you happen to come across a used Rotel 1072 in good shape, I would buy it without hesitation. Best entry level CD player I've ever heard.
