Hate to double post, but I wanted to post an update: I finally bit the bullet and ordered a pair of E5Ti's for my fronts and an E5Ci for my center. It's kind of a big deal for me, because I've been going back and forth between different floor standing speakers for over a year now. I haven't listened to them yet obviously, but I already feel better, mostly because I finally made a decision.
I'll be using my KEF 2005's for surround, although I'll probably upgrade those as well later on. They're great speakers, but I'm sure they're not going to really perfectly match these EMP's. I'll be using my KEF sub as well, since it seems to do a pretty good job.
