I have another interesting observation. I've been using the M100s in my main room since I got them. With the M2 acquisition, I took all fronts out of my main room except for the M2s and M5s. I've noticed with either of those, my QS10s are casting images towards the front that were not there with the M100s. This is a very, very cool effect for both music and movies. I perceive PLII and other surround formats as more natural. Almost like there is more space for each speaker to do its job. I surmise the large soundscape from the M100s is drowning out some of the surround radiation even in this large 4,200 cu. ft. space.
