Help with CD Player

Wanting to buy the best unit I can for the money. Used only on audiogon. Must play cdr. sacd/dvda not important. Will be using with Krell hts. Would like to spend no more than $500.

You could buy the new Rotel the TAS raved about recently for about $550. A friend has one and loves it.
A Music Hall CD-25 is a remarkable buy in that price range and can be easily upgraded for even better performance.
