Hmmmmm...these are very interesting thoughts. I have folks who listen to my system in 5.1 and cannot believe I don't have overhead speakers. Case in point: in season 5, episode 5 of Breaking Bad, when they lifted the methalamine off the train, Jesse let the train pass over him. Well...that train was right on top of us. It was truly astounding. I had nothing like that kind of an effect or dynamics with QS8s. Like you say, it's likely because of my room dimensions.
Regarding the dynamics, that is something that doesn't get talked about often. The QS10s are incredibly dynamic. I am sure my QS8v2 were compressing.
