Summary: The system is very difficult to set up and the remote sucks. The sound however is excellent and linked very well with my Panasonic's TV Viera Link so was able to use my Panasonic's remote to control basic Denon's receiver function
Summary: After weeks of researching which receiver will work best with My Samsung LNA750 and PS3 I went with the Denon AVR2309ci. I couldn't be more happy with my first receiver. Blu-Ray and video games sounds great. I Have the Onkyo SKS-HT540 7.1 speakers hooked to it and it shakes my living room up. I Have my HD cable TV going in HDMI and that too sounds great while watching TV. I also pulled out the old GameCube went in S-video and up-converted it to 1080p via HDMI cable.
Summary: This is a solid, flexible receiver. I gave it only 4 stars because of the learning curve involved in setup. Trying to name/remap inputs, assign audio formats, or manage the remote has all of the usual idiosyncrasies of a Denon receiver. This said, once you do get this unit setup, you will be very happy. I don't think there are any better consumer audio components available, and the 2309 is in the sweet-spot of quality and features.
Summary: I've always been a Denon fan; a great work horse system. I recently upgraded my AVR-1804 to the AVR-2309 after purchasing an HDTV from Amazon. Although I can see the point of reviews claiming a set-up which wasn't overly easy and a manual lacking in some detailed information, it really only took me about an hour and a half to have all seven speakers and all audio/video connections swapped from my 1804 to the new unit.
Summary: I bought this receiver to replace an aging Sony STI-910 receiver when I upgraded the home theater system with a Sony PS3 that we use for blu ray movies and games. The first thing you'll appreciate is the automated speaker setup and synchronization system. It makes life pretty easy and eliminates the need to manually calibrate the sound output for your room. I have a fairly big room and was surprised how accurate it got my speakers tuned.
