I'll second the comments on the Acurus A150. I've been through several different kinds myself (Carver, Marantz, etc), and settled on the A150 and 100X3 for a 5 channel setup, with the A150 driving the front L/R. You can find clean examples of the A150 for $300-400. It's still the best 2 channel I've heard for under $1000. By the way, while we're on the subject of Mondial Designs, I don't think you can beat the Aragon 8008BB for under $5000 (list is $2750), or the Palladiums for under $10K (list is $5500). I'll admit I'm a Mondial fan, but the sound to value ratio is hard to argue with.
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)
