There are many Usher dealers, including me, but Katli does not list them. I am a massive fan of Usher speakers and have experience with almost every model, including the T-515 that is a rarity to find in the US. I got a second-hand pair of Be-10 and immediately upgraded the tweeters - the difference was not subtle. The diamond tweeters are some of the best I've heard, bar none. If you think several hundred for a pair of diamond tweeters is expensive, try and get a pair of B&W diamond tweeters...
