Summary: Although the price tag for these is a bit high, if you can get one discounted, refurbished or in excellent condition for around $400-$500 you won't be at all disappointed. The main feature I like is having 2 HDMI outs. I have a TV and a projector and there's no problem switching between either having both on at the same time. The menu can be complicated, but if you take your time you can find everything you need and set up the unit to suit your needs. Excellent purchase!
Summary: This is my 7th Denon product . I have never had any problems with any receiver or DVD player. My only issue with this is the User Interface UI. It is not the most friendly, but is loaded with features. The problem arises when you don't use it often and have to figure it out again. The quality of sound is outstanding and has plenty of power. I use it for surround and playing music.
Summary: I bought this on the gold box deal for 50% off a while ago. It has been fantastic! 7-1 sounds amazing, Blu-Rays and video games kill through the surrond sound. Couldn't be happier!! It's on nearly 24/7 and stays fairly cool. Impressive power when needed. Easy to use controls (a first with Denon for me) and easy to use remote (also a first for me with Denon...no more double sided nightmare). 5 Stars.
Summary: the 3312ci in not availible so they shipped me a 3313ci. The price was very good but really wanted the 3312 for it's features that were dropped on the 3313 new model version. The set up speaker didn't work had to find my old one from my 2807. took for ever to find the correct combination of setting to get the 7:1 to work, still working on the zone 2...... My 2807 was much friendlier to set up.
Summary: I bought this Denon receiver almost a year ago (6/2012) to hook up my whole house speakers to use with Airplay and Pandora. I loved the feature set and the sound quality is very good. The menu system is awful, especially if you don't have the video output connected. Just using the remote to set up is a big pain. With regards to the features and functionality, I'd give it a 3.5 / 5.0, but given all the issues I've had (below), I'd have to drop it to a 2 stars now.
Summary: Bought this May 2012. Worked fine until this month, June 2013. HDMI board completely crapped out. Cuts in and out. Looked into Denon service, no local servicers, I will have to ship to service center at my expense. Awesome. Thanks Denon. Will never buy another Denon. Buyer Beware. This is a KNOWN issue with the Denon HDMI boards, look around.
Summary: I just love the fact that the new generation receivers comes complete with the audio setup microphone. My previous receiver did not have it, but now I could use this one to complete the setup for both. I bought this receiver because I have so much joy out of the previous one. My only issue with the older unit I have is it did not yet come with HDMI.
