Summary: I have been very happy with the sound qualities and features of this unit. A couple of the drawbacks are: poorly written manual and buttons that are impossible to read without a flashlight (grey on black). However, the big issue is that after 2 years I have to get it repaired because the Headphone Input is faulty. I have never used headphones, but it started triggering on automatically (and sometimes switching back and forth).
Summary: The good: 1) Good build, finish & features for the price. 2) Stays cool & does not get hot like older generation Onkyo AVRs. 3) Definitely better than AVRs that come with most HTIBs. 4) Ideal for bright sounding wall mountable satellite speakers. The bad: 1) 90 watts/ch rating is untrue. Onkyo AVRs with the same power rating has almost half more juice.
Summary: I read a lot of reviews, and most complained about the manual and remote control. This is very true. The manual is so difficult that I still have not figured out the features. The speaker set-up through Audusey was difficult, because the manual was not clear on how pick the six positions for the mic. I like the sound, but am not clear on how to get the most out of it. I'm sure it will take some time to get adjusted. It took two week to get it to work.
Summary: You cannot use any s-video devices with this unit; the s-video port is solely for use with a Denon iPod dock (not included). Some composite sources (Super Nintendo, Nintendo 64) do not work with this unit; they will play sound, but there is no picture output over HDMI. The manual mentions this limitation, but neither Denon's website nor J&R's website does. Furthermore, resolution auto detect is faulty.
