I 2nd the McCormack suggestion. I have a DNA-500: Detailed, musical, remarkably controlled bass, loads of finesse, tons of power(500w into 8, 900w into 4) - it doesn't get much better than this under $15K. Also built like a tank. Can probably be had used under $5K if you look. Lots of rave reviews are actually on the money (for a change) regarding the DNA-500.
