mikeak, re your mains, I think you'll find the RC-70s(which I also auditioned) have a very different sound than Axioms. Although I respect Energy as a speaker company, I felt that the RC's were "muffled" when compared to speakers such as Axiom, Paradigm and Monitor Audio's to shortlist a handfull of speakers I auditioned. I can't comment on Emotiva speakers having not heard them, but I suspect they are well built as many of Emo's products seem to be.
Unless you really NEED to have in-ceiling speakers, the QS8's are a very compact(heavy little suckers) and quite unobtrusive when wall mounted on the included T-brackets.
