Is the RBH really an upgrade over the Denon? Isn't it an older unit? To really see a benefit from power increases, you will need to double or triple the power from the denon. If you figure that by going to one of these processors first is a good start, then great. There is no use in going to the Integra units that I see. Go for a pre/pro that can handle your satellite outputs. Then from the pre/pro to the Bravia.
I'd really push you to use the digital outs from the dish reciever to the pre/pro and analogue outs from the receiver directly to the bravia for when you aren't using surround.
