What speaker has the best tweeter?


I love the AMT tweeters in my speakers. They are definitely different from other tweeters I have heard. I enjoy their openness and air. But there are qualities of other tweeters that excel in other ways. Some v pricy speakers use beryllium or diamond or diamond coated beryllium. I see that the price of, Seas I think, diamond tweeter is like $6K a pair. Then ribbons offer used. Not to mention plasma, etc.

As for just the tweeters themselves
Magnat MP-02 Plasma is the ultimate tweeter, I have a pair nothing else approaches them, the surrounding burning gas becomes the 360 degree diaphragm. (and is as light as air)

followed by horn loaded Plasmas, then ESL’s, then Ribbon/Planer then domes.

I’m not in the market for another speaker. Have my destination system including my speakers. Just wondering about the performance of different tweeters. 
Those plasmas look excellent. Then there is the v important issue of the crossover. And already $4500 why $600 for shipping?I guess a/the major thing is how light the moving elements are.
So, nothing compares with light as air.
I have never heard better than whatever it is that Stenheim is doing/using.

With that said, my Focals keep me very satisfied.
