Summary: it worked great for the first year or so, then the HDMI inputs decided to stop transmitting sound, I was able to fix it by completely rebooting the system like 4 times but it still does this regularly, I have searched forums and even contacted Denon about this problem and they keep telling me it...
Summary: Worked well for 13 months, but then I lost a middle channel. Kids didn't notice when I disconnected the middle channel lead, so all was well. Then, 3 months later I lost the right rear channel. Will never purchase Denon again.
Summary: My Denon 1909 died within two years of purchase. They repaired it under warranty, but now, less than a year after the repair, it died again this weekend. For the kind of money they charge for their products, I sure would expect a longer life span than 2 - 3 years.
Summary: In spite of the good reviews, I've found this equipment to be utterly dissapointing. Here's why this is a crappy product you should avoid: 1) Had to factory reset the unit several times. Would stop detecting DTS or PL-II or anything beyond PCM.
Summary: The 791 does not work with the iPhone as advertised. I contacted Denon and all they would say is that the problem is either with my phone or with the cable. They are refusing to admit that there is a problem and based on the customer service for this product, I would stay away.
False Claims About On-Screen Display; Does Not Work With Iphone

Summary: I've had a Denon receiver for ten years (an AVR-2800). I switched to this because I needed one that with HDMI input/output. I'm used to the opaque Denon manuals and non-intuitive interface. However, the AVR-1911 has two debilitating problems. 1) It supposedly has on-screen display.
