Yamaha RX V775 7.2 AVR with remote, Functions perfectly as 2-channel stereo, plus sub out, as it's been lightly used for the past year. Previous to that it was used in a 7.2 home theater setup until a failure in the surround sound aspect (surround satellite channel stopped working). Why, I have no idea, could be a simple something, or something more complicated, like a failed surround channel amp...I don't have the brain and equipment to deal with it. We've moved on, even from daughter's room stereo duties. You're welcome to come audition 2-channel, or pickup/meetup as you choose.
