Summary: I have had good luck with Yamaha in the past so I gave this one a shot based on it's "zone 2" abilities. I had it up and running in minutes and the unit performs very well. I am not using much of it's video switching capabilities but it works well for what I have tried. The zone 2 funtion is just what I was looking for. You can control two areas from one remote.
Summary: A very good receiver so far. I haven't had a chance to fully explore all the functions yet. Set-up a little problematic for balancing the speakers using the microphone. Kept getting errors for no reason. Manual needs improvement for novices to understand.
Summary: This is a step up from my theater-in-a-box set up and could not be happier. I had it up and running in 5 minutes (no special configuration),connected my Blu-Ray, U-Verse box and my HTPC. I'm still in the process of exploring all the different audio settings but so far the sound has exponentially improved from last system.
Pros: Easy Setup, Good Power Output, Great Sound Quality
Summary: Do not overlook this product because of the price. The Yamaha RX-V665 has 1080p upscaling as reported by the Yamaha web site. The RX-V665 has YPAO Automatic System Calibration just like the big boys. The sound is good and the 7.1 decoding is as good as a high priced receiver.. I have not finished playing around with the product but am impressed so far.
Pros: Accurate Controls, Easy Setup, Energy Efficient, Good Power Output, Good Remote Control, Great Sound Quality
Summary: So, overall I'm really happy with this receiver - it does just about everything they promised it would, and it sounds spectacular combined with the Polk speakers I bought to go with it. But.... One of the reasons I bought it was the promise that I could seamlessly connect all my video devices and it would convert them all to HDMI - so that I wouldn't have to set the TV and the amp whenever I wanted to watch something.
