Oldgrey,
Welcome to the neighborhood.
I would happen to agree with TedB & Hford653,(& Ted you have a nice system & room) 2 channel & HT can coexist in the same room. Yes utlimately I would love to have 2 separate rooms, but that for me is financially impossible. I would much rather throw my money at one room & of course my equipment. If you do a build I recommend you acoustically set it up for 2 channel (if that is your first love of course). I followed this road & have been very pleased with the results. Equipment selection & synergy are also important.
Hope to meet a few more of the Cleveland area audionuts in the future as well.
