I like the set-up you have laid out.....but I have two concerns. The first is with the QS8's. If I see it right your listening position will force the QS8's to be at different distances from you. Would that be correct? Second is the spacing on the 60's. Is there anyway you can have them at an equal distance on either side of the TV?

Is this mainly a HT set-up or do you listen to a lot of music? I'm also still thinking on your sub. Is it behind the M60? You may get a lot of "BOOM" with it. Any chance of bringing the TV out on an angle and say having it more or less face the fireplace?
