Diamond dome tweeters

I’m not a fan of the overall sound of B&W speakers, but I have to say I was impressed with the tweeter in the 804 and 802D3. I can’t seem to ever warm up to most metal-dome tweets that almost always grate on me at some level, but I got none of that with their diamond tweet. I personally think Usher crushes B&W on every level and also make their own drivers, so I’m finding myself very interested in hearing their newer speakers with both a diamond tweeter AND midrange drivers.

The Seas Excel motors are a whole other caliber of driver vs. the B&W.  Two other diamond dome makers I know of are Jantzen (not sure if in production) and Accuton.  I trust Troels ears a great deal, and he described the Jantzen diamond tweets like I describe the Mundorf AMTs so...

Oh, I think Crystal Cable made speakers using the Seas diamond, and JA at Stereophile did an absolute crap job reviewing it.
