Summary: Bought this about a year ago on amazon for $586 (no tax or shipping). Main concern was to get quality audio sound and RCA pre outs for Klipsch XF 48 amplified tower speakers (required speaker RCAs to use built in amps). Had a Denon 1609 and liked the sound, so I knew that would be nice. Have yet to use a lot of the fancier features, so no firmware nightmares haha. Has a lot of flexibility which I'll probably use to bi amp a pair of Mirage OMDR rear surrounds.

Summary: Alright, so I have had this unit since December of 2009. I run this thing pretty hard, and unfortunately make it work harder by pushing my quite large Axiom M80 4 ohm speakers; the receiver is only good down to 6 ohms. I know this isn't great for the receiver, but I am too poor to buy a separate amp. Also, this thing runs about.... 12 hours a day, at least, 98% of the time. I am always home always listening to music.
Summary: If you don't have a 3D TV this is a great steal! The new model, 3311ci is $1300 and only adds 3D HDMI compatibility. The built in Rhapsody is super cool, although the Denon has lost it's network connection a couple of times, not sure why considering everything is setup DHCP. HDMI devices sometimes don't sync if you send a command (like volume down) before the Denon and HDMI source have done their DHCP handshake.
An Affordable and Feature-Rich 7.1 A/V HDMI Receiver

Summary: Pros: Serious number of inputs; 5:1 surround sound; output to (2) sets of speakers Cons: None, no really Bottom-Line: The Denon AVR-2310CI works and works well and I am glad I choose it; it works for now and there is still ample room for expansion. So it was time for a new A/V receiver with at least (4) HDMI inputs, 7.1 Surround Sound, a Phono (turntable) input (these are next to impossible to find on any receiver expect higher end boxes), at least 100 Watts per channel...
Summary: I had been scoping out Denon's and other brands for a while. I finally decided on this unit due to it's features and price point. I highly recommend the Denon website for comparing different XX10CI models. So far, I have been happy with my purchase. It has a whole host of features including up-converting all inputs to HDMI, HD Radio, Sirius capable, 5 HDMI inputs, 3 audio zones, and completely re-assignable digital/analog inputs.
Summary: Purchased this unit in the spring and have had no issues. I have a firmware upgrade screen pop up that, based on all the reviews, I have ignored. I called Denon and they also told me to ignore the update. Only problem I had with is was it was pretty confusing to customize. If you just do a basic out of the box set up its fine, but when you want to do some more advanced features (i.e. "video select"), it can get frustrating. Theater sounds good, I'm pretty happy...
Summary: I bought the AVR-3310CI for our main surround system and after several months of very satisfactory performance, I later purchased an AVR-2310CI for our bedroom system. Both receivers replace nearly 10-year-old JVC models that still work fine, but lack HDMI outputs. Purchase of new LCD TVs & Blu-ray players prompted purchase of the new receivers.
Summary: I received the first one, hooked everything up, turned it on, and got nothing but static. I called Denon to see if I had missed anything. They had me reset it. That didn't help. They told me to return it. Amazon replaced it. The second arrived - hooked it up & turned it on. No network connection. I called Denon again (not very helpful). They said that the card must have loosened during shipping. They again told me to return it. Amazon sent me a third.
Summary: I purchased this to replace an Onkyo. I researched this receiver in comparison to a Yamaha and a Harmon Kardon and selected it due to good editorial reviews by Stereo Review and others. It has plenty of power and it has video upscaling (the comparable Yamaha did not) so your non-High Def channels look better. It has mulitple zone audio so I can play music on my deck while others listen to TV in the family room. It also runs cooler than my Onkyo.
Summary: The receiver has been great - sound quality with my polk 70 series floor speakers has been awesome using standard speaker wire and banana plugs. The instruction manual is not user friendly, and I have some issues where the receiver refuses to read non-HD signal coming in via HDMI cable (i.e., when watching regular cable on an HD tv).
