I've used a BAT 3000SE for the last 3+ years. Built like a tank. 150 watts per side. Hybrid, so two tubes in the pre-ampstage. It lists at $8000, but I believe cosmetics will change soon to be in line with new BAT look, so you may be able to get one new for your price range. In fact, there was a time a few years ago when Music Direct had a sale for $5600 (naturally, a few months after I got mine!).
The only reason I'm trading mine in is to upgrade to D'Agostino Progression. So, you should be able to get used for $3000. (If you are interested let me know.)
