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 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.
