I am curious about this as well. I did search for info on this but didn't find what I was looking for. Probably because of the server crash. I have both a SACD and a DVD-A player and am currently using the two Radio Shack switches to change inputs to my ICBM. The ICBM output then goes to the 5.1 input on my Denon AVR3300 which I am using as my pre/pro. I have a ATI 1505 that I am using for my amplifier. I am not sure how to use the Sony as a switch. Would I hook it up like this?
-----------------------TA-P9000ES
SACD 5.1 out------>[ INPUT 1 ]
DVD-A 5.1 out----->[ INPUT 2 ]
DENON 5.1 preout>[ 5.1 BYPASS ]
----------------------[ 5.1 OUT ]--->ICBM---->AMP--->SPKRS
Greg & Mark, read my response to Mark's post in the 'audio/video source' section. Greg, after reading your schematic I think it will work but then the switch box I mentioned at the end of my post should work for you as well presuming the Denon will allow you to adjust gain from it's 5.1 inputs.
