Summary: I just bought this as a working receiver. I updated the firmware on Denon's server and the files were corrupt. Now nothing works except the switcher. The HD radio drops out and motorboats. The USB inputs look nice but DONT WORK!!! It freezes when I select any Network function and has to be turned off and then on again. Denon told me to drop dead!! Denon used to be a reputable company with very good electronics. They also used to care about their customer base.
Summary: This is my 3rd Denon avr receiver (Avr-3802, avr- 4306 where my first two). Nice update to the GUI interface. Lots of power, I like the Audessey eq set up, and the sound is, well, that wonderful Denon sound. Many features (I don't use most) but it has everything I need (HDMI 1.4, with ARC isn't on this but isn't an issue for me, if you need it, get the AVR-4311).
You "are there" sound imaging with outstanding multi-media and multi-room capability

Summary: The Denon sound has always been pleasing to my ear, but the AVR 4310ci receiver has taken their outstanding sound to another level. This has seven discreet amplifier circuits so you can drive up to seven speakers, or configure them to bi-amp speakers designed for it. It offers many choices for multi-media control and playback for both video and audio, with assignable HDMI, component, composite, digital coax, and digital optical inputs and outputs. Highly recommended.
Summary: Let me start of by saying that I am in the industry and know the ins and outs of this product. This is one of the most robust products that is out there, and that is why I own it. I have read several reviews on here and wanted to address some of the gripes that people had: - Remote: Denon has never been known for intuitive remotes, and most importantly they should not; since the remotes are designed to be put away after the installation.
Summary: I bought this set for around 1 year. Play most of my music from my computer wirelessly. I am pretty much enjoying the feel "everything under control" from my laptop. The HD radio classic music sounds perfect but sometime will crash due to unstable internet service(it's a bug from Denon. I return one for this but the new one has the same problem). For playing PS3, it sounds like I'm actually in theater "LIVE GAME".
Summary: This is a terrible receiver. I have never had the HDMI switch properly. You need to turn the machine on and off if you make a switch from one input to another. Also, the ethernet capability has never worked. I have had the unit serviced 3 times, but it has never been repaired.
Summary: Took a bit to get it set up with some reading and playing with the options, but it was well worth the research and time needed, the quality of the sound exceeds that of my Sony Receiver and having 7.1 surround makes a lot of difference in my media experience.
Summary: I like Denon receivers, and this is my second. It replaces an AVR-3808 that was fried by a lightning strike that also took out the surge suppressor. I was lucky I could buy the older model because I use SiriusXM satellite radio using an XM adapter, and the newer receivers no longer have ports for that device.
I bought a lemon and got terrible Denon customer service.

Summary: I have had this unit for 8 months now. It had green video lines on the HDMI output the day I got it. I had it repaired under warranty (2 weeks). Then it had issues with the HDMI audio intermitently stuttering. I took it back to the repair shop and they couldn't reproduce the issue, but they did something to my receiver because when I got it back it was playing 2-ch stereo only.
Bad UI, HDMI handshake problems, networking broken

Summary: This was my first Denon receiver. I've bough high-end Onkyo before this but decided to splurge with a local audio store (Listen Up) and get a Denon receiver. Honestly, not only is the Onkyo a better value, but it's easier to use, hasn't failed, and doesn't have HDMI handshake problems. Also, I can't tell any difference in audio quality (I mostly watch TV and movies). Paying the extra money for the Denon was a waste.
