Scott,
I have a Revel Performa setup for my fronts and got a great deal on Focal dipoles when Tweeter went out of business. I also had a small cube set of cambridge soundworks that I all setup in a 7.1 configuration a few years ago. Then, I when I switched to BluRay, I didn't have 7.1 inputs on my receiver and went down to 5.1. It should be noted that I noticed some timbre matching issues with the cambridge soundworks, Focals and Performas. So, I went to 5.1 with my Revels and Focals. Finally, I picked up a used set of the matching performa S30 surrounds and WOW, WOW. No 7.1 equivalent has ever bested the setup. Simply put the timbre matching and also the fact that the S30s are a grade up from the model focals I had simply was stunning. The NEW sense of envelopment and detail blew me away. Mind you, I'm in a *very* large room and some schools of thought would say I really need 7.1 just because of size. So to your question, while I would want to think that the more the better for speakers, I think the real thing people need to realize is that the quality of the speaker will always best the number of speakers... and I'm running my audio with an old Anthem AVM20 preamp and a Lexicon amp to drive the speakers and when it comes to multichannel uncompressed audio via the analog inputs, it's simply stunning and breath-taking.
