Summary: I have lived with a previous Sony receiver since the late 1990's. As HDTV and 7.1 surround capabilities began taking a foothold I knew I wanted to upgrade again to something that would last another decade into technical change. I turned to Sony again because of the flawless track record of my previous receiver. Having read a lot of reviews, I was concerned about ease of set up and user friendly menus and remotes.
Summary: When my previous Sony AVR box developed a burn out on several speaker outputs (probably because I shorted them out when trying to screw speaker wires into the terminal pads), I shopped for a new one. After years of being a Sony Fanatic, I have come to the opinion that the Sony of my youth is not the Sony of today. HOWEVER, with regards this new unit, it would be unfair for me to be so libelous. This unit has been very satisfying, with only a few blemishes.
Summary: This is an excellent system. The audio and video are both as good as anything I can hear/see. It has amazing flexibility and connectivity. I am able to do a few "technically challenging" tasks with it (using 2 audio zones, with video of DVD photos on a TV in one room, audio from a different source - cable TV music - and 2 HD TV's in different rooms running simultaneously). I realize that some to the features I want are not the everyone else's criteria.
Summary: It's nice to be able to switch up to 4 HDMI components and have only one HDMI cable going to your TV carrying the audio and video signals. The auto calibration is pretty accurate and very simple to perform. I purchased a $275 sound pressure meter to check this. I have to say that my audio settings were set wrong for years by my ear with my old receiver and then an auto calibration option saves the day.
Summary: Excellent Receiver, if you're thinking on which receiver to buy Onkyo or Sony. Go with this one. I mean everything is better than the Onkyo. The Onkyo receiver is nothing compare to this one. A friend of mine has the Onkyo 606, and man I telling you my Sony is a lot much better than the Onkyo. Each bit of it. I love it. I'm happy with my receiver.
