Does anyone prefer the sound of the M2s/M3s over the QS series? I am still having to take a few shortcuts due to my budget and the QS4's are realistically out of reach. Just wondering if there are those who prefer the direct sound of the bookshelfs vs. the ambience of the QS series. I have heard a few mention that with the QS speakers in movies, sounds/effects can be difficult to place, which can be a positive or a negative depending on your point of view. I guess without listening to both as surrounds it is difficult for me to see if the QS series would be my preference.
