Best used amp for around 500

First, thanks for the recommendations. Didn't expect such a quick response. I'll do some searching to see what amps I can find to listen to. As to Sean's question, I'll likely use the receiver as a pre-amp/processor until it is replaced with a more suitable component. What do you guys hear about the Chiro amps? Also, I recently saw an Odyssey Stratos that has been highly rated - anyone ever hear one?

Stratos: Heard it and I like it if you go for the SS sound. Good prices on used. Get the 120,000uF cap upgrade.

I remain,

Yes the Odyssey Stratos is a great amp. But they usually go for 700 dollars used.

Dan,

The pre-amp portion of your system has as much, or more, effect on your overall sound as does the amp. This is why people are asking about whether you plan to use your receiver as a pre-amp -- your receiver will continue to be a limiting factor. You might want to see if you can borrow an amp somehow to test with, and buy it only if it really gives improved sound. Perhaps a store in your area that sells used or demo equipment?

Ehart gives good advice. Is why I suggested a tube pre amp but that's my prejudice. He is right that the pre is important.
