I prefer most 2 channel music in stereo ... some things sound great in music surround formats but it's too much to switch modes depending on what is playing ... for back ground music ... some room surround modes do a better job of filling the room. Just MHO.

On the QS8s I'd use them some place where you were not planning on doing Atmos for expense/space reasons. I'm putting in/have/had a few 5.1 and 4.0 spaces in my house.
