I am too a happy new owner of an Outlaw amp. The 7700 arrived two weeks ago and its been a nice improvement to my system. I am still using my Rotel RSX-972 receiver as the pre/pro until the 997 comes out. The 7700 drives my Scan-Speak Ultimate Revelation Kit speakers for the fronts and Totem Mite-T s for the center and the rears (sides are coming). For power, I installed a dedicated line from my breaker to a Belkin PF60 in which I attach all my AV equip except for my LCD display. I receive very little hum speakers and no hum from the amp itself. Only when there is no sound playing I can here alittle bit of hum from the speakers. It is very faint and you have to put your ear to the speakers to notice it but it is there and where the Rotel had non before. However, the 7700 brings fuller sound at higher volumes and fills my HT with a sound that puts a smile on my face.
