Thanks, SQ...I've got the same speakers as you, except M22s instead of a second pair of QS8s. I recently moved the M60s to the living room for stereo playback and moved the M22s to the front of the theater. Now I'm down to 5.1 but, I plan on getting a second pair of QS8s for the back. It's like everyone says...those QS8s are fabulous sounding and I believe they will work fantastic for surround back, as I guess you could attest to. I have a Panasonic AE700 projector, 106" Da-Lite Cinema Vision screen, Denon 3805 and Denon 5900. I bought an Onkyo DX-C390 (6 disc CD player) and a Denon DRA-395 for the living room...hence, the M60 move. The Onkyo is very decent sounding, but every once in a while I break the 5900 out of the theater rack and use it in the living room when I'm in a concentrated listening mood.
Sirquack, a safe and prosperous New Year to you and yours!

If I were truly plastered, could I do this?
