Summary: Bought one of these some time ago from an authorized retailer over the internet. The unit is very flexible, powerful, and sound is very clean. As some others have said though, the user interface is not that great. I have been using it in 5.1 with zone 2 and zone 3 (kitchen and deck).
Summary: I owned this product for about a week. Had nothing but problems from the very beginning. I am big on buying products on-line. I usually spend a good amount of time reading both professional and customer reviews and try to make a decision based on that.
Summary: Fire the Denon Engineer that was in charge of developing the feature, which is the subject of this rant... It took me about 1.5hrs to get this receiver all set up, with its intricate menus, submenus & even subsubmenus!
