I need a reccomendation for a CD/DVD combo

Hi - I know this question has been out before but I ws wongering what the current thoughts are.

I have a pair of Meridian DSP 5500's they are speakers, amp and digital pre in one.

I am looking for a new cd/dvd player or changer to put through them - the source will need to have an audio coxial out to run directly into the speakers. - By doing that I think That I am bypassing the d/a converter in the source and using the meridians for the d/a conversion right?

I have seen a Nakamichi DVD 15 that looks interesting for $400. But if possible would like to spend a little less.

I like used gear, too --> please reccomend some models.

thanks
David
