I was astonished, a few years ago, to see a pair of KEF-branded bookshelf speakers on display at a Super Target, for somewhere between $300 and $400. They were actually hooked up, along with a number of pairs of less expensive speakers, and so I listened -- they sounded so much better than the others that it wasn't even funny. As I stood there, a Target salesperson came by and asked if I needed help -- when I explained that I was admiring the KEF speakers, she said "well,if you want them, better buy that pair -- they are the last ones we have, and we can't hardly move them, so we aren't getting any more. Too expensive."
I can remember when KEF was THE prestige speaker brand in the U.S. -- now nobody talks about them and you can hardly find them here at all -- not even at Target. Infinity and Klipsch were prestige brands, and now they're just more mass-market mediocrity. Maybe it won't happen to B&W, but I wouldn't bet against it.
