Anyone own Onkyo home theater receivers?

I have a nice set of Onkyo surround speakers. A friend of a friend found her BF was cheating a few years back, seperate apartment and all, and gave away ALL of his stuff. She wanted to keep the receiver since it was already hooked up to everything else, but gave me the speakers, wire, and two stands. I was hesitant, but was assured that if somebody didn't take them that they would be in the dumpster. I'm using a Sony receiver for the speakers and they sounds great.
