Go with a single disc cdp, you will get better sound.

Whats your budget?

Here's a Marantz changer- http://us.marantz.com/Products/3069.asp

or this Yamaha- http://www.yamaha.com/yec/products/p...l?CNTID=451769

If you must have a CD changer and want better sound, then consider a changer with an optical out and use it as a transport connected to a higher end DAC to do the digital to analog processing.
