you can find a cambridge 840 pre within your budget; nice piece and aesthetic and operating match for your cdp. parasound 2100 and arcam fmj (which i'm partial to) seem to meet your criteria.
Preamp recomendation
Looking for advise on a good preamp. Under $1000, solid state, at least treble and bass control capability, and a remote control. Am currently using a Yamaha cx-630 preamp, along with original Legacy focus speakers, Hafler 9300 power amp, Cambridge audio 840-Z c-d player, Morrow MA1.1 interconnects, and staightwire laser 8 speaker cable.
