I run a Denon AVR-5800, the reason features, features and then there are the features. Seriously the amp is capable of driving pretty much anything that you would consider putting into your home with power to spare. I first purchased a Denon AVR-3801, this is also a good amp to drive the M80's it has good power and lots of nice features. I moved this to my family room and bought the 5800 for my HT room.
