I did hear Mini Dancer 1/2 with diamond tweeter.
I thought top end extended a bit higher, a bit more airy, and a bit more neutral. compared to BE tweeter, BE possess a sweeter, richer, and more romantic tone while diamond is more neutral and faster.
depending on your taste, I like both but lean toward BE since Usher BE is already very transparent, extended, and airy when compared to other top tweeters.
