Looking for advice on amp/pre amps...

Hi all, i'm new to Audiogon and i LOVE it! I'm looking for advice on amps/preamps. I can spend in the $2k price range, maybe more. I listen to all types of music, mostly pop/rock. I'm looking to power my Paradigm Studio 100's. I have little to no knowledge on this subject, but am willing to do research and take advice. I'm going to listen to CD's and watch movies and would like to have a nice surround sound set up. I guess thats all, please help! thx, Bob
