I'll be most likely purchasing an Onkyo 1007 or 3008 if I get more sold on XT32.

I'll be running Heights but probably not Wides yet.
I've heard Heights>Wides on reviews at AVS, but Wides>Heights according to Audyssey? My room is narrow, so I'm going Heights.

Why would you want to use something like the QS8 for Heights?

Why not direct-firing speakers?
