Kharma CRM 3.2F vs. Avalon Eidolon and Diamond

I saw that Martin Colloms' review of Eidolons referred to by Linkster is now posted on the Avalon website. Audiomgu, if you're still pondering rather than listening, this is a worthwhile read, since it gives an intelligent and well-understood assessment of the speaker characteristics.
Then make sure to hear all of your contenders - they are probably all top-class.

I have a friend that I implicity trust, some of the best ears I know of. He has listened to the Accuton Diamond tweeter in the Eidolon during a demonstration atempting to sale it to one of the major recording studios (he owns several recording studios). His response, was, it sounds like a diamond...Hard. The best tweeters I have heard by far are the Raven 2.0 and the higher end Focals, including TAD.

D911: very interesting, I found them to be light and airy compared to the ceramic tweeter in the plain jane Eidolon. And even lighter and airier than the titanium tweeter on my
Radians. The plain jane Kharmas use a soft dome tweeter
(revelator?) and have as an option the diamond tweeter. I heard both the Kharma 2.1 and various Avalons and all perform well; personal tastes at this level is what matters.

I've heard Diamonds sounding hard and aggressive in the upper frequencies too and think it's probably related to room setup. The room I heard them demo'd in was too small and had too little sound treatment. From Shubertmaniac's comments, it seems clear that like the Eidolon, the Diamond needs careful room setup.

Flex: where did you here the Avalon Diamonds? I heard the
Diamonds at Overture in Delaware with an all Spectral
setup. It looks like the same room/setup as the plain jane
Eidolons; which sounded at one time terrible (see my
tirades with cfb about the Eidolons). Avalons, in particular the 3 ways, are very tricky to setup
properly.I have the Radians and I am still dialing them in after 5 months of use. The Radians use the MB Quart titanium tweeter, 3.5 inch kevlar/nomex midrange, two 9 inch kevlar/nomex woofers. Midrange is excellent, the bass fairly good and the lower to mid treble is very good, and the high treble is good but not nearly the best I have heard. My Accoustat's high end is sooooo much sweeter! But for an eight year old tweeter design, not bad, not great.
But I would not call it steely or hard, more like a dull sound; same goes with the ceramic, and the diamond not steely or hard, just less dull than the ceramic or titanium.
When I say the diamond was light and airy, this was relative to the plain jane Eidolon and the Radian. I might agree about a ribbon could be better( though the first time I heard the Apogee in 1984 with krell electronics at the original Bryn Mawr stereo store, I almost ran out the door, it was so awful sounding). Same goes with electrostatics.
