Seas Excel Diamond tweeter or Plasma?

Interested in building a speaker using, I think, the most expensive “conventional” tweeter available at $6k a pair for the Seas Diamond. I only want to use the best drivers available. TAD 15” woofer, ATC dome midrange and a great tweeter.
I well appreciate the art/science of speaker design working with an established Speaker designer.
Surely the enclosure and crossovers are critical. I lean toward the Diamond but not sure if the Plasma is better.

 I have no desire for exotics for the sake of being exotic.

What we are after is natural, uncolored, dynamics, nothing **warm**. 
Warm = coloration, murky lower midrange. 
Of all SEas mid tweets, the only 2 I am interested are the Thor's Millennium and tyheir *Flagship* Cresendo. 
The Millennium is a  incredible midtweet, natural,  voices the human voice with stunning realism. 
a 3 way witha  midrange, would upset this and add warmth, 
The upper midrange of the midwoofer meets perfectly the lower midrange registers of the Millennium, xing ,,, I think 1800hz
Here is a good discussion on xover points. 
To my ears a  3 way sounds blaring/dominate , mushy in the mids, Mids are 80%+ of the music. = a  more simple xover of midwoofer+midtweet is the ideal design for capturing clean, clear critical mid fq's. 
There is no need for a midrange in a  MTM design. 
Midtweet  = superior to   tweeter./midrage combo.

here's no best, there's a best for a specific application and intention.


I would agree with **There is no best,,,*

I've looked at every  SEAS tweet, and wondered if anyone actually employs the Seas Diamond. Most expensve= superior..? I am not convinced .
**Money no object*  may not result in *best ever speaker*. 
Makes sense to build on SEAS drivers only, as i've found SEAS makes the finest, most musical voice coils/cone material, magnet designs. 
Look if your customer wants a  speaker that is superior in musical reproduction,, 1st what is his source and then amplification power. 
A exceptional speaker, hooked up to a  avgerage sounding other components, may only result in just a avg speaker.
laying out that kind of money, synergy is critical. 
I am not convinced, expensive drivers = superior speaker. 
btw I also am interested in Mundorf's AMT Ribbon . But then keep in mind ribbons have that kooky characteristic of The Narrow Sweet Spot, Can't deal with that weakness. In order to have M's ribbon work, is a  row of 3, = $$$$$.
Keep us updated on the final design and give us a  test YT vid. 
We all want to see exotics in action.
