What's the best sounding dome tweeter available?


I'm thinking of trying the DIY route for a pair of full-range speakers. In your opinion, what is the BEST dome tweeter available and the best place to buy it?
Thanks and happy listening!

There is one dome tweeter in this world that is completly over the top. It is the new Professional line Vifa Ring radiator with a housing machined from solid aluminum and triple tetraheron rear absorption chambers, manufactured with the best materials that Vifa could think of, and manufactured to the tightest tolerances that make their other top tweeters look like a joke.

With the above in mind, I THINK THAT THIS IS CURRENTLY THE BEST DOME TWEETER IN THE WORLD. It is built to such exacting standards that Vifa rejected virtually the entire first production run because of slight variences that they were trying to perfect.

It was recently tested by a speaker designer in europe and he declared it the fastest least colored tweeter he had ever heard (AND HE'S TRIED EVERYTHING!), and he said it was the first dome tweeter that had the speed of a ribbon, but with much better dispersion and dampening charactaristics i.e. the best of BOTH designs!

Now here's the kicker, the retail cost for these unique professional Vifa ring radiators are $1000.00 for a pair. For this price, it better be the best!
The Esotar tweeter is my favorite. The kicker is that they are $1000.00 each. I ahve them in my Extremas and there is nothing like them.
Dynaudio is not selling raw drivers to the public anymore, but if you can find a pair of Esotars floating around somewhere, buy them. If not, or if you're concerned about replacement ability, Scan Speak is the next best choice.
That VIFA RING radiator tweeter really sounds awesome..seems to qualify as a top 21st century driver...i may have to eventually get a pr...put that with the scanspeak 10 inch woofer. or the focal 11WX..WOW!!!
VIFA RING(1K) + SCANSPEAK 10 (500) + xover + cabinets..for under 2K... and what commercial could touch it?
