this is above your price range, but, I am super happy with my purchase.
RCVTech MPA-1200 monoblocks. 380 wpc 8ohms, 700 wpc 4 and 2 ohms. Beats my Mark Levinson 532H amp, more detail, more bass, more stereo separation, just plain better.
I considered Buckeye Purifi Eigentakt but I live in Canada, and if I need service, RCVTech are a few hours drive away.
My longstanding friends all thought I was nuts to upgrade, and now they are blown away. I am not affiliated in any way with this company... lol
