Some advice needed

My current set-up is as follows:
JM Lab monitors, center and rears
James sub
Panny 50" TC-P50V10
Arcam AVR 200

I'm looking to make the move to a new, upgraded receiver. Can anybody recommend a decent one in the $1k-1.5k range? I know the argument of separates vs. single receiver runs deep, but in my budding audiophile experience I don't think I'm ready to appreciate the difference yet. Suggestions are welcomed!
I moved from an AVR200 to their AVR350...not enough difference in my opinion...In other words I would only make a change if you need some extra oomph for your speakers. Otherwise I think you should wait to afford something more to truly realize an upgrade.

Thanks very much for your suggestion, Bob. Are there any good "starter" multichannel amps you are particularly fond of?
I've used Parasound amps for the center and rears - they're a good bargain. Also B&K.
