Summary: I used to have a Yamaha 5.1 receiver that worked for about 10 years and still working. I replaced it with RX-V575-R because of the newer technologies in modern receivers. I got this unit as a refurb which was substantially cheaper than the new.
Summary: I have been using this and the RX-V475 for about 4 months now on a daily basis and like them both. I bought the 475 first for about $200 reconditioned and thought it was such a deal that I bought the 575 twin which I use to drive both indoor and outdoor speakers.
Summary: Very nice set of features for a reasonable price. Hooked up Samsung 50" HD TV using HDMI cable, automatically syncs the sound perfectly. Very intelligently made, nice looking, fits the small space available in the TV console perfectly.
Pros: Clear Sound, Easy To Set Up, Interfaces Well With TV, Lots of inputs, Supports Airplay
Summary: I bought this to replace an older (but not THAT old) Onkyo whose HDMI board had died (apparently common for the newer Onkyo receivers). I got a great price on a refurbished unit. This unit exhibits typical Yamaha quality and features and I really like it.
Summary: Overall very happy with the purchase. If I were to do it again, I would have upgraded to the one with two true zones instead of shared. I installed speakers out on the patio and in the living room, so it's nice being able to turn one zone on and the other off or vice versa, but you're forced to use...
Summary: My only dissapointment with this product is that Zones A/B can't handle different inputs. It's not clearly stated on the website and the manual, found that limitation on a web review. And that was what I was looking for on a two zone receiver. Maybe it's my fault, or maybe not.
Pros: Clear Sound, Easy To Set Up, Energy Efficient
