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 can design one no problem .
i can design one with 93 real dB s if i have to , mine go perfectly also with the ayon spark 35 watt triode they stay very dynamic .
Mike lavigne has also experimented with real low output designs

The Coincident Pure Reference/Extreme use this driver and work very well with low powered SET amplifiers.
I think that both the Coincident Technology Pure References and Pure Reference Extreme's sound great and they both have Accuton midranges and tweeters, but with Nomex 12" woofers, which are also great. Of course, the skill of Israel Blume in making the crossovers and the cabinets probably has a great deal to do with their extraordinary sound quality, particularly when paired with their own Frankenstein amps and Linestage.

I have Salk SoundScapes with Accuton midranges. Looking at the Accuton driver’s frequency response, I can see how the key to getting great sound from ceramics is a great crossover. Many speakers do not have crossovers that good. My SoundScapes have a great crossover. The frequency response is very flat. They sound very natural. I have the speakers playing all day long and get no fatigue.

My tubed Aesthetix Calypso preamp makes magic with these speakers with Telefunken tubes. They are very natural sounding. The transparency is as good as I have heard on any speaker. That being said, I can see that others might prefer colorations that other cone materials might bring. That has to be a personal decision. My previous speakers had Seas Excel Magnesium midrange/woofers. They added an excitement to the music that I loved. The speakers, that I had before them, had Audax TPX cones. They added a bloom to strings that was to die for. That bloom was not there in live music. You have to decide what you want.
