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.

I am waiting on my Voxativ, 
My hunch it will present the best all around highs,
So tweeter choices? 
I have no idea,
Good luck with the search. 

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.
