Summary: This receiver is incredibly difficult to use. This one was replaced by Denon for failure on the first one I owned. Terrible. My bro-in-law also has one slightly better than mine and regrets that he even considered it. I am amazed by the number of these products I see at WalMart thinking all the way about the suckers who are going to buy this.
Summary: Regarding AVR-2307CI, This Receyver Amplifier push lot of power and is installed with Klipsh Surround system, I purchase this because the newones are so expensive and compare to this don't provide the sufficient power and is a replacement of my old Denon amplifier that was burn. Now my system is restored in a very good deal.
Summary: I have owned Denon AVR's for many, many years. This unit was of interest because it switches HDMI as well as retaining S-video and Red/Blue/Green rca inputs so older devices can plug in. I bought and returned an O---o receiver that sounded fine, but they had abandoned S-video input, and the amp sent out interrupted audio for several seconds when TV signals varied in format sent as it recognized and "caught up" to the change. Denons don't do like that.
Summary: One of the top of the basic line of Denon, or the first of the top line of Denon, is the same that the AVR-887 electronics, only are diferent the front face, the strongest thing of this models are the HDMI support, Neural Surround system & that are XM ready, it have 5 digital inputs, 3 opt & 2 Coaxial, the RS-232 control port & that the front face are aluminium made.
Summary: This system is an excellent system for the price. I have everything hooked into it. 42" plasma tv, souround sound speeker system, ps3, vcr/dvd player, directtv hd dvr, sirius unit, and even a turntable for records (remember them?). The only problem with this unit is the remote. You need to be a rocket scientist to understand it. To solve this problem get yourself a logitech universal remote. I have the harmony 880. Now everything works great.
Summary: This receiver has good features, but the set-up is difficult. Once you've mastered the set-up, the system perfoms admirable. I recommend you use the "lock" feature once you're satisfied with the setting, because if you decide to tinker with them later you could have a mess on your hands and have to redo the set-up.
Summary: I bought one in July, played about 4-5 movies, and it's DEAD, I opened the metal top enclosure as I wonder maybe the fuse was burned, well, I can't believe what I saw, the 2 AC input receptacle housing metal contacts were loosen from the PCBA, it seems to me a defect of "cold solder", the other AC bypass housing was came off the PCB as well, no wonder when I set it up, the AC outlet on the back has never been worked!
Summary: I feel I have gathered enough experience on the Denon AVR-2307CI in the past 5 weeks to be comfortable to share my opinions with others. Prior to purchasing the 2307CI I did my homework and found the two major complaints against the 2307CI are 1) the layout of the remote control, and 2) the receiver's on-screen menu is only visible in 480i mode.
Summary: I purchased a new system from a local authorized Denon store who is a reputable audio/video dealer. They came and unpacked the boxes and set up my system including an Aquos 42" LCD HD TV, the Denon 2307CI, etc. to mate with my new HDDVR from DirecTV. The set up included use of HDMI cables for all video and audio between the new components. After set up everything seemed to be working fine until the first time I turned it on when the technician wasn't present.
