So as some of you know I have the architectural onwall speakers.
w22s
w150
ep350

I'm getting ready to buy the qs8s. What kind of difference in movies can I expect from adding these surrounds?

Also how many of you use these while listening to SACD music?

PeachTree 65se, PeachTree D5 and SVS SB1000 - Stereo
M80s, M22s, SVS PB3000
