content: Excellent sound quality, not too hard to set up but when using my PS3 through the HDMI input, the receiver produced a loud switching noise every time the audio over HDMI went on and off. This happened for example when starting/stopping a movie. It was so loud and weird that I feared damaging my speakers so I returned the unit. Totally unacceptable. I thought it was my unit , but apparently other people have experienced it as well.Got a Yamaha 661 for $25 more and I don't get the weird noises anymore.
