Suggestions for my system: Preamp?


Especially for a recent college graduate, I am lucky to have such a nice stereo. It includes:

Magnepan 1.6QRs
NHT 12" powered subwoofer with an external crossover
Arcam CD-72T
Bryston 4B

Currently, my father's old Yamaha prologic (bah!) receiver is serving as my preamp. Also, I have AudioQuest cable, some decent interconnects (50 to 100 bucks a pop, not toooo expensive but not toooo cheap), and a Monster HTS1000 power conditioner.

I've been told that I really need a replacement for the Yamaha preamp. However, the entire aforementioned system was purchased for only 2 thousand dollars. Because I really don't have much cash, I've had to find excellent bargains and values.

So if you could kindly drop some suggestions for preamps that cost less than 750 used, I would appreciate it! My two criteria are: 1) It must be of sonic equivalence to my other components and 2) Must be able to send my towers AND my subwoofer a signal without using a Y splitter (i.e. the preamplifier must have more than 1 set of outputs). I really don't know where to begin looking, so thank you for your help!

The Classe CP-35 is vastly superior to the Adcom. It's got a lot better bass and just more life (better dynamics) than the Adcom. Oh, and don't listen to what people tell you about tube preamps sounding slow. They've obviously never heard a good one. Anyway, you'll be happy -- at least for a while -- with a CP-35.
9rw may be correct about the dynamics of the Classe CP-35, I don't know fisthand, but it falls short on one of your major criteria - multiple outs for sending the signal to your main loudspeakers and your sub. The Adcom has two sets of RCA outs, one set of XLR outs and one set of tape outs. The Classe has only one set of RCA outs, one set of XLR outs and one set of tape loop outs. FWIW...
Are you sure about the Classe? I thought I saw a diagram that showed it with two RCA outputs... I could be wrong :)
Baltman, there are some Bryston BP-20 preamps for sale here on A'gon for less than $750. Perfect. Newer design than your amp and well suited for any future "upgrade."
