I'm looking for a 5 or 7 channel surround amp which has multi-zone capabilities. I.e. you can watch telly in one room via the amp and listen to a CD in another room with the same amp from a different source (CD in this case). I know the Denon 3802 does this - but do any others? I heard that the 1803 does this - but could not find any details on the denon website.
