Good budget CD with variable out??


I'm trying to put together an acceptable office CD-only system. I have a Rotel RB-951 amp and JPW ML-310 speakers gathering dust. What CD player with variable out could I use for about $500 (new OR used) to get decent sound? Thanks in advance!!!

I have an Audio Electronic CD-1 for sale in the classifieds for $600.00. It uses a Marantz CD-63 transport mech. and remote (with volume control), but with a much, much improved chassis and (single-ended tubed) output stage. Really magical sounding, especially straight into an amp!! Audio Electronic is Cary Audio's entry level line. I paid $1500 2 yrs ago. NOT a budget cd player.
