RMC Audio Direct has them for less than MAP/MSRP. They said $600 per S8, where as the MAP is $750 (and thus what most people charge). You have to call/e-mail for a quote, of course, but damn is that some savings :D.
 
I decided to get a set of S6s to see if I like the speakers. If so, 2 S8 and another S6 will follow.
