Summary: Sounds great...but have not had time to read the manual and set up the system with the mic. Commercials sound level is not consistent with shows/games, so I need to learn how to fix that too. Center channel on sports broadcasts seems to be too quiet too.....probably some way to fix that too.
Summary: This is an awesome receiver. I have a mix of 4 and 8 ohm speakers. I did a lot of research before I bought the Denon because most manufacturers tell you their product can't handle the low ohms. Not Denon, they said their receiver would handle it, and it did. I tried the auto setup using the mic. It did not do the job for me. Once I set it up using manual set up it sounded the great.
Summary: I did a lot of research before settling on the 2309. I listened to several systems and the sound quality was well worth jumping up to this level. It is also the only one in this price range that had 4 HDMI inputs. I would definately suggest getting a side by side comparison before purchasing this system. Doing that made me confident in my purchase of the 2309.
Summary: When I first started to hook up my new 2309 I was expecting to have a difficult time to get it going based on many reviews that I read. To my surprise the hook up was easy. When I got it going I was blown away by the sound. I hooked up my Panasonic BD30 blu ray player and played Dark Knight Returns, the sound and video was top notch. My home theater speakers consist of 2 JBL E80's, 2 JBL E50's, 1 JBL ES 35 and my subwoofer HSU VTF-2 MK3.
Summary: I was a little nervous ordering this based on reviewes from people who had a difficult time setting this baby up. I ahd alloted two hours of setup time to intergrate into my setup, and debug, etc. I was done in a little over 1/2 and hour. And most of that time was the audyssey/mic setup. Otherwise, I'm amazed how easy it was to set up. If you connect your HDMI devices into the suggested ports, the Denon will see them and there is aboslutely nothing to configure.
Summary: I use this receiver as my main home theater/audio hub in the main room (about 15' x 20'). I was honestly a bit worried about getting everything set up based on reviews I've read. Many people have said that the OSD interface is antiquated and difficult to use. I tend to disagree. While it isn't a fancy super intuitive Apple-like interface, if you're used to interfaces found on products such as Onkyo (my experience has been the TX-SR674), then you'll have no problem with...
Summary: Denon released 2309CI pretty recently (Even BestBuy doesn't have this model in their inventory yet.) After few weeks of research I decided to go with this model. I am glad that I did. My setup is KEF 3005 speakers, Samsung LN46A650 LCD, Atlantis set-top (can't remember model), Year 2000 Panasonic DVD player. 2309CI mint all these devices together without any issues. Sound and picture quality is amazing.
