FWIW, I got a pair of Polk LSi9's a few months back. They absolutely blew me away with the clarity of their sound. They made me think that I finally understood what people mean by "transparency." I had to return them, though, because they could not handle high volume levels from my HK 3480 receiver. The woofers began to rattle about -8. So, it was back to my old B&W's. Too bad. I really did love those Polks, but I can't always keep my music at "moderate" volume levels.
