I have a Yamaha RX-V2700, which is considered to be a fairly decent receiver, but I'm using it as a pre-pro. At the moment, I have three front (4 ohm) speakers powered by Outlaw monoblocks. (The Yamaha's amp section is bypassed.) From my research, it seems a lot of audio/HT people take this approach. That said, I am interested in learning more about the Emotiva UMC-1.
