  • newegg HDMI support for 3D Video and Audio Return Channel The HDMI implementation on this receiver supports both 3D video and an Audio Return Channel, along with numerous high-resolution formats. 3D video brings exciting possibilities to home entertainment, with movie, game, and broadcast content on the increase and 3D-compatible TVs now on the market. Meanwhile, the Audio Return Channel allows audio content received directly by your HDTV’s tuner to be sent “upstream” via HDMI to your A/V receiver, without the need for a separate S/PDIF audio cable.
  • newegg Marvell Qdeo Video Chip for 4K Upscaling and Processing The Qdeo is a suite of QuietVideo processing technologies that produces quiet and natural video free from noise and artifacts. Using this technology, you can enjoy 4K upscaling and processing for your contents for a more stunning video experience.
  • newegg Dolby Pro Logic IIz Adds New Dimensions to Surround Sound Of course the receiver supports high-definition audio formats like Dolby TrueHD and DTS-HD Audio to give your Blu-ray Disc movies's soundtracks unsurpassed audio quality. In addition, Dolby Pro Logic IIz brings the added dimension of height to create an immersive 7.1- or 9.1-channel surround sound experience from any stereo, 5.1, 6.1, or 7.1 movie, music, TV, or game audio source.
  • newegg Network & DLNA Support With the network capability, the receiver delivers Internet Radio reception and Network Audio streaming via Ethernet (optional UWF-1 wireless USB adapter supported) from Pandora, vTuner, Mediafly, Napster, Slacker, Rhapsody, SiriusXM and more.

Audyssey Dynamic EQ for Loudness Correction solves the problem of deteriorating sound quality at lower volumes.

5 out of 5 eggsGreat Bargain

Pros: First and foremost is the cost, 300 off on a complete 7.1 system.

Hook up is very simple with included diagrams and manual.
Has plenty of HDMI inputs for all your needs.

Hooked up my PC to receiver then to my TV, decoding all my movies audio to correct channels.

I now get the WOW factor when playing movies. I actually have gotten some of my family to jump up from their seats when a sudden scene change happens.

I am loving this so far.

Cons: It could have come with longer speaker wire, I had figured it would ship with short wires so added another 100 feet from another vendor on my order.

Firmware was not up to the current update, but connected to the net is easy to download and install through the receiver.

Mine did not come with a mic. :(

Other Thoughts: I have never been much into audio and bought this as to finally get the thrill of a theater sound in my living room. It has plenty of power to make my floors shake and looks very nice with the polished black speakers. If you are like me and don't really hear a differance in the very fine audio sounds but still want a good system I would say get this system for the price and you won't be dissappointed.

5 out of 5 eggsI love this thing

Pros: wow new egg had this $200 cheaper than anyone.

1. It comes with a mic that plugs into the unit to automatically setup the surround sound to the correct settings.

2. It has a universal remote that seems to work with almost anything.

3. sounds awesome

Cons: 1. doesn't have wifi. you have to buy that seperate for around $50. It does have though but I didn't buy it for those.

Other Thoughts: I bought this to use with a 73" mitsubishi and an LG BD670 3d blue ray player. So far everything sounds awesome.
