Best used amp for < $500?


Poor college kid here. (we all were at one time, weren't we?) I'm looking for a good 2 channel amp for possible main usage, or possible bridging for my THX sub. I'm trying to keep the cost down below $350, max $500. What are my options? (I've looked at used Rotel, Marantz, NAD, Carver, AudioSource, Adcom)

Forte, Van Alstin, Acurus and Rotel are all good choices. Go to featured dealers in this listing. Go to Hollywood sound, he has the Acurus Dia 1oo integrated for 595 and several other models. I have bought many things from Larry, he is totally reliable.
Electron Kinetics Eagle 2. If you see one, jump on it. Vastly superior to NAD and Adcom. The on/off switch is notorious for going out, but can be replaced. Will drive a .5 ohm load all day long. Designed and built by the (late?) John Iverson.

The PSE Studio IV is the best amp I know for under $500 used. It matches the Eagle 2C (also excellent) in bass when driving 4 to 8 ohms and is sweeter and smoother overall. I have not heard the Belles 150A. I would love to hear from anyone who has AB'd the PSE against the Belles.
