Is the Accuton driver that good?

It seems a lot of new speakers are using the Accuton or similar ceramic drivers (and I notice the diamond variant for tweeters). I've heard them (mainly in Kharmas), but not others. Evolution, Salk, Avalon, and like I said Kharma use them.
Do they have any particular coloration or quality that is making them gain popularity? In the Kharmas, it was pace and timing and a natural sound without overhang, but it was different than regular (non-metallic) cones & domes, which, fwiw, are less detailed but maybe more relaxing.
It's like for me with the Kharmas "this sounds great and real and not bright or hard either" but somehow it is not as relaxing as the Aerials or Von Schweikerts or Quad dynamics(or even Apogees) I have lived with). I can't put my finger on it.

I'm not sure if it was just the Kharmas or the ceramics in general, but I wanted to raise the question.

I just love all the wrong uninformed posts by those who feel they have a grasp on loudspeaker design. Keep it coming I need some humor.

Charles1dad, I did offer PHY loudspeakers but I do find there to be other transducers that are better sounding for less outlay. That being said PHY km30sag and other PHY transducers are great for acoustic music but to me a bit colored and the baskets causes issues with difraction that other full ranges or coaxils do not have trouble with. I also design with accutons these transducers do require more work with crossovers to get the best out of them but this is common with many modern transducers so not just accuton and to give accuton credit there newer transducers are a bit easier to design with. One can design a good sounding loudspeaker with either. Myself I use massive horns or full-ranges with super tweeters or 2 way ribbon hybrid designs. I tend to be drawn towards lower power amplifiers so this also steers me into loudspeakers that work well with such. If your more into SS or high power tube etc. Then a Accuton equipped loudspeaker might be the better choice. If low power amplifiers and simplicity of design appeals to you then PHY might be a good option for you.

SEAS X-1 Fostex f200a fostex fe2008e sigmas with t900a or t500amk2 tweeters still less cost than PHY. Or better yet a compression front horn speaker. Problem with PHY is the price more than performance. They to me are not cost effective for performance given. Plus the need for massive OB to get the best out of PHY any other cabinet besides massive OB is a compromise and limits performance of PHY. If going PHY consider h30lb15 sag and RAAL. Over km30sag. I do enjoy full-ranges wide-bands but none are close to front horns in performance.
