Thanks for all the info everyone, Sean - most of what you posted is on my list to check out, hopefully, some will be displayed for listening purposes when i get around to it, otherwise, I'm sure I'll be coming home with about 10 sets and returning 9.
I've also got some Advents, Acoustic Research, Polk, Energy and Paradigms on the list to review, I've always been partial to Paradigms for indoor speakers, may as well check their outdoor stuff out.
Well, this will give me a little fall project to do, the wiring will probably get done over the winter since most of it will get pulled through my attic which is the most direct route and winter is a good time to work up there.
Heck, maybe if I go big I won't need to get another system near the pool - although our town may not appreciate THAT!
