You don't understand my classification, lets just simplify almost any uber high tech metal based driver is going to sound detailed, clean, transparent, wether or not a particular listener is going to find all that clarity to be too much is a matter of personal taste and system setup.
Pure Ceramic drivers also tend to sound in this camp ie the Acuton's used in Kharmas original speakers.
The only uber high tech tweeters that have mega clarity, speed, and articulation while also sounding smooth, Acuton Pure Diamond drivers.
(we have a set of Polymers which use these drivers)
If you look at all the speakers that tend to fit into this camp, almost every one of these tweeters goes up to 40-50k or above.
Vs.
Soft domes, Heils, Electrostatics, very rarely have I ever heard a Heil driver with the same level of uber clarity then the above camp, generally more detailed then a soft dome fabric driver, and more air.
Electrostatics all tend to be shelved in frequency response above 16k,
and most soft dome tweeters even if they extend to the 20k and above range all tend to be smooth and musical with less "apparent" detail then the above camp.
Have you ever heard a "bright pair of Harbeths or Sonus Fabers or Quads Electrostatics?
I rest my case.
Lets make an analogy to a coffee drinker,
You got pure black coffee, all the detail can be a bit aserbic for many people.
You got the little bit of milk or half and half guys, a bit more toned down and slightly altered, from the above but you can still taste the coffee.
You got the little bit of milk and a bit of sugar, guys, another step towards changing the taste and cutting off the aserbic nature of the unadultarated pure black coffee.
and finally,
Coffee with a lot of cream and a lot of sugar, now you have changed the coffee into something else.
You see my point, which Coffee drinker are you?
Persepective is a very unusal thing it is a shame we all don't have one.
