Thank you, Sushi. No enclosure for the M60s in your opinion (mine too I think), lighting is moot (especially since I don't yet have a projector of any type), and the QS8s need at least 4" or so.

To go 6.1 (with dual rears), or 7.1, I would need to do an asymetrical speaker set up.

More questions:

-QS8s would be better used as sides rather than rears, if I had only one pair, correct?
-Would QS4s as rears be superior to conventional bookshelves in an asymetrical set up (hybrid tweeters vs 1" tweeters).
-How seriously should I take the Denon manuals suggestion to not place speakers further than 16' away?
-Can the non-ported VP100 be used as a rear surround? side surround? (that would be ideal due to room constrictions - one on top of the mantle and the other under the overhanging bar in the kitchen).
-In the above scenario the QS8s would be rear surrounds. From what I've heard about 6.1 and 7.1, this would be a waste, no?

Thanks again, people.
