You then would hook up the 12v Trigger from the 123 to the passthru input of the C2700.
What this will do, is all your 2 channel sources go to the 2700, say turntable streamer, disc player etc. When you listen to 2 channel, its the 2700 and 255 powered up only.
When you power up the 123 to watch a movie, the 12v trigger turns on your 2700 automatically and puts the 2700 into home theater passthru mode. This disables all eq/source selection/volume etc of the C2700. Your front channels of the 123 simply pass through the C2700 to the 255 amp.
I did that for a few years with my HT processor and C1100 pre-amp.
Just note not all McIntosh 2 channel pre-amps have passthru mode. Just look for the input on the back or check the manuals.

Question:
Is passthru solution reduce Audio quality ? ( Both in surround and Stereo modes. )
