I had the same issue with audible clicking with my Onkyo 805 receiver. This can be solved by assigning a default surround mode to each input.
I just placed an order for the DHC-80.1. It will be my first surround processor since my Lexicon DC1! It seems to fit the bill for all of my requirements: XLR outputs, firmware updates via ethernet, room correction, latest variations on the codecs, video processing. Each of the other more expensive contenders did not meet these requirements in one way or another (Anthem requires windows computer for ARC, Classe does not have room correction or video processing, Bryston will likely not have room correction) except for the Denon, but could not justify the price difference on the Denon. I also don't want to end up with an overpriced boat anchor, like the Theta Casablanca or Lexicon MC12. Performance with analog sources is not a factor for me, as I have a BAT VK-52SE preamp for my CD player and analog front-end. I will report impressions once I have spent some time with the unit.
