Just a suggestion. Ron at New Record Day did a sound demonstration of 4 amps here:

It features the Rogue Audio Cronus III, the Black Ice F35, the Galion TS120E which mostly are in your price range. The fourth amp, the LTA Z40+ integrated, is not in your price range. I don't know anything about your speakers and I'm not making any recommendations but given the comparison, maybe this sound demonstration will help or give you some ideas.
