I'm seriously considering getting one of these. I currently have an Onkyo DS797 that has served me very well over the years (yes, I upgraded the chip), but I now have a lot of HDMI devices and need something a little more powerful to drive my Totem 4 ohm speakers.
I was seriously considering the Onkyo 805 or the Denon 3808ci, but now I think I'm leaning towards the Marantz. I know of a local store selling both the Onkyo and the Marantz so I'll be taking them for a test drive sometime in the near future although I won't be buying until after Xmas.
I don't need any fancy video scaling as most of my input devices are 1080i and my Panasonic plasma seems to do a pretty good job of scaling anyway.
My only concern is the low weight of this device compared to the Onkyo. And why on earth do all the manufactures insist on having all those composite inputs and outputs?! I'd be more than happy with the following inputs: 5+ HDMI, 4 optical, 4 coax and 2 of each (max) for the older devices.
I'll also be buying a HD-DVD player very soon, so I'll be checking out a few threads in the appropriate sections on here.
