Advice re: Entry level CD Player

I've been putting together my first audio system, and could use some advice. Right now, I have a NAD C325BEE Integrated Amp and Mirage OMD-15's. I'd like a CD Player, and am thinking about getting a NAD under the theory it may match up well with the amp. My budget is about $500, and I don't mind going used. I've noticed a new NAD C545BEE, and also a used Creek Evo....

My listening is eclectic, but not heavy rock or rap. In addition to CDs, I listen to my computer based music via an "iDevice" thru a HRT iStreamer. The plan is eventually to upgrade my computer music to FLAC or AIFF files and get a decent DAC, (which may also service this soon-to-be acquired CD player.

A newb has to start somewhere!!
