Thanks Chess, that was very interesting. Previous to my renovations I only had a 5.1 system with Paradigm Atom's as my rear speakers. I will obviously get a lot more from my Monitor 9's which I think will have a enveloping sound. With the new upgrade to 7.1 I will try the QS8's for my rears first (won't partially blocked my doorway which is another advantage over my 9's) and leave my other 9's for my side speakers. The parable that I am in, is that I have never heard a speaker specifically designed for surround sound.
