I too would recommend the Aerial 10T, which I believe continues to be one of the best buys available and pretty easy to find in the upper end of your price range in excellent condition. Unless you have a very large room you do not need a high powered amp to enjoy these speakers, but the minimum recommendation is generally 100 watts per channel. I used a single BEL 1001 MK3A, which is 50 watts per channel for a year or more and was very satisfied considering I traded up from a Classe CA300. Today I use two of the BELs bridged mono (200 watts)in a 13X22 room and that is all the power they need in a room of that size.
