Try a Jolida. They have various models in your power/price ranfe. I've owned/own high end ARC, CJ and Melos tube equipment and I use a Jolida 502 in my bedroom system. You can get them used for $400-600. I personally think that you can't beat their price/performance unless you want to build one yourself. They turn up on ebay more frequently that here. Replace the stock tubes. I use KT-88s as the ouput tubes and NOS on the drivers. A Dynco Stereo 70 would also be a good first choice but a little lite on your power requirements.
