Since I now have some time to play around with this concept I have an additional question. The Marantz pre has two RCA pre-outs. Currently, I am using one for the Amps and one for the 1500 Array. Would it be possible to use a Y-splitter on one to both the Marantz and McIntosh amps and keep the one for the Sub? Don't they have to have the same impedance or am I way off base?
Please excuse my ignorance on this matter.
