Summary: OK so I figured that if I bought a higher end receiver I'd get higher end quality. WRONG! This piece of Chinese junk has had the Ethernet card go out twice now. And when taking it in to the service center they never have the part available so it's a two month wait while the part gets shipped from the far east. Save your money and buy something more reliable, my last receiver was an Onkyo that was built like a tank and was still going strong but had no support for HDMI.
Summary: Ordered this from warehouse deals at Amazon, 1st time they sent an old Denon amp from a few years ago in the right box, this one was correct but have not been able to get it to work. This is a beautiful amp with lots of menus, connections, looks like the internet radio would be fantastic-if only I could hear something. We have tried playing from radio, cd's, radio, rewiring all of the speakers, trying just two of them, plugging in headphones-never a sound.
Summary: There is a problem with Denon 2310/3310/4310 receiver line playing TrueHD and DTS-HD Master Audio track when connected to LG, Samsung or JVC Blu-Ray players. The receiver shows that it is receiving the HD audio signal from the player and the HD audio blue light comes on the front of the receiver but then instead of sound you get a "helicopter" like noise or no sound at all coming from the speakers.
