Personally, I think you lucked out. I'd keep the m22's. When I look at your setup I can not help but giggle a little. My woman always had a thing with putting TVs in the corner - and I hate it. She gets it from her mother of course, who always had floor model tv's, yup those ugly ones, shoved into the corner of the living room. LOL. TV's do not belong in Corners.
The only thing with the QS8's is that they make a very clean and tidy setup. Where bookshelves for surrounds are anything but.
Now, order that center
