I was just reading an older thread here titled "QS4 vs QS8 ...." back in 2007. It was good and enlightening. It's the one where the surrounds were placed on soup cans. From reading this, I have decided to stay with the QS8, but to downgrade the center to the VP100, because it had more clarity for smaller rooms. The VP150 required more volume for the same sound.
