I have owned several speakers w/RAALs, including Vapor Cirrus 2 ways currently, and while I enjoyed them all, if I was to spec new speakers I would probably opt for the Satori BE.
All the RAALs I've used have great strengths in detail retrieval, but they don't blend perfectly in 2 ways, I've found, and sound a bit dry in 3 ways, not quite disappearing into the soundstage as much as some others.
My other 2 systems use Accuton ceramic and Dynaudio T330D cloth domes, and they both blend better and simply sound a bit more musical, at least in my Avalon Opus 3 way and Egglestonworks Fontaine 2 ways.
Each of these great tweeters has strengths and weaknesses, but I've not gotten the ultimate musical naturalness on top from any of my RAAL speakers, I'm sorry to say. YMMV.
Still great sounding, but at this price point I think there are other options to consider, and I respect JS's opinions.
