Has anyone heard the Cambridge Soundworks Newton S300's? I really like the fact that they have a switch on them so they can run in monopole, bipole or dipole modes. I've found a couple reviews, but the reviews are usually of the entire system and don't really focus on the surround speakers other than to say that it's cool that you can switch between the various types (mono, bi and di). I'd love to get the Axiom surrounds, but they're a little out of my ballpark right now. I don't think there's anywhere nearby that sells the CSW's where I could listen to them . . . what retailer does sell them anyway?
