I just purchased a new Toshiba HD DVDP and unfortunately my Proceed AVP will not support 5.1 analog inputs from a source device. My options are just run the standard cable back to the PRE and carry on. The other option is to look for a processor that will support this functionality and take advantage of true HD sound.
I also own a Proceed AMP5 and that will be staying for sure. So what I would consider down the road is a processor that will support balanced IC's back to the AMP (5 of them) and only because this is the way it is connected now. No sense changing all of the cables. I want some really good functionality that can totally switch over to 2CH if I want (not the main rig) and support multiple devices. I am running HD from cable on a Panasonic plasma in a 5.1 environment. No need for more than 5.1. I am probably thinking a couple of grand ($2K) or so for the PRE. Any ideas as to some good names for me to consider. Thanks folks.
