Summary: This is a great receiver - when it works. The sound quality and customizations available are unmatched in this price range. You will need a PhD in electrical engineering to fully appreciate (and use) all of the complex features, but if even a basic enthusiast can enjoy this thing - again, when it works. But I won't repeat what others have said about the features. The problem I have had is that mine has lost video output from the one HDMI out - TWICE.
