Mike;

i'll let you know on wednesday? I've been told that mixing sat reciever manufacturers (with direct tv at least) is not a problem. I got a system over the holidays and have RCA and Sony boxes being hooked up to it on wednesday when the install happens.

If your talking stereo recievers / amps, i dont see why it wouldn't work. It should just be another input. I'll know that on wednesday as well.
