Acapella ion tweeters

Does anyone know about Acapella ion tweeters (specifically the TW1S)? I would be interested to know about the following:
1) If you have any experience with them, are they really the best out there? Are there are other tweeters which can match their speed? Are there others with similar technology?
2) Did they have ozone problems at one point or do/did all extant versions of the TW1S have it licked?
3) Are they now available separately? I remember reading in a post many moons ago that they only came as part of their speakers (I believe the mysterious Detlof was the author) but the website has a separate listing for them. And if available separately, does anyone a) have ANY idea what they might cost? and b) who in the US or Europe (or even better, Asia) might sell them?
Thanks, Travis

Vahe, hearing is believing. You cannot even imagine how good they are. I couldn't either until I heard them for the first time and I'm not even exaggerating. They are probably the most important piece of equipment I've ever obtained in my long career as an audionut and they are worth every buck spent. Besides, don't forget, they are powered, have their own dedicated tube amp, are built like a tank, completely ozone free and beautiful to look at.

Hey, guys check out http://www.ee.vill.edu/~cdanjo/plasma2.html I once had Ionovacs. They were truly exceptional, making you think all other drivers were crap, which of course is true. I tried them with double Quads, Linn Isobariks, Fulton Premiers, and even Klipsh corner horns. They always stood out as better than what they were mated with. Ultimately I gave up and sold them.

Since the Acapella tweeters are the outgrowth of the Ionovacs, I am truly amazed that they can pull off mating the tweeter with horns and an enclosed woofer.

I have Beauhorns and have been tempted to try plasma tweeters, except that I well remember my experience with the Ionovacs. I am, however, looking for a pair of Coronas if anyone, Detlof, knows where I can find them.

Norm sorry, have no idea, where to find Coronas, in fact I must admit, I didn't even know they existed. You are right, it is quite difficult to mate the plasmas with the rest of the system and I found, I could only pull it off together with my stators, when I gave them a dedicated amp and preamp chain, so I could tune them in the way I wanted it.(Spectral) The effect on the soundstage, apart from the highs of course, was phenomenal.
