Receivers and Audio Components

Is there a good site where the various recievers and speakers are ranked?

Also, what are your suggestions of a set-up (reciever, speakers and cables) for the following needs:

1. Would like a 5.1 kind of a system

2. Budget is around $700-$800

3. My living room is not too big... so power might not be a big factor.

4. Sound Quality is extremely important - people consider me to be an audiophile

I mistakenly hooked up the AM loop antenna to the FM side of my Philips FWC155 Mini Hi Fi System. I immediately unhooked it. When I turn on the radio it will play great for a few minutes but then it will get fuzzy and a strange distorted sound will come from the speakers. The CD plays great. What have I done??

Thanks
