I have been through more than a few amps, and have to say I am very happy with the BHK monoblocks. I have owned a Mac 452, Parasound JC1 monoblocks, Moon monoblocks and a few other not so notable. The BHK are my favorite, with a close second being the JC1s.
Also, the BHK amps have an obvious synergy with the BHK Pre that I just love. Lots of good deals on PSA amps out there as well. Fun problem to have. : )
