I never weighed in, but I had my QS8s on stands (ear-height) for a long time, and I was always happy with the result. My side surrounds are currently raised higher, since they have EP800s under them, but my rear surrounds are still on stands.
I want to move to Atmos, but I'll wait until UHD Blu-ray has been out for a little while, and I'm curious what other offerings Axiom will have at that point. I'm hoping there will be something for people with lower ceilings, since this is the space I'm stuck with. I bought one set of M22s in anticipation, but, like you, I'll still try out the QS8s to see how they perform.
