"Sizzling" tweeters at high volume?

Sedond, I find the Focal titanium tweeters to be the worst of the lot. Followed next, by the tioxid(TiO2). To my ears, the Kevlar tweeters are the least offending. I have also noticed that these tweeters are very system dependent. With a laid back tube amp, the Kevlar tweeters can be OK. With more forward sounding tube amps(I heard them with Rogue stereo and monoblocks w/Rogue 66 preamp) or many ss products, they send me running as fast as I can in the other direction. Of high end tweeters, the Focals are by far my least favorite.

Good luck with the new speakers Sedond! I presume when you say Accuton drivers, you mean the ceramic(Al2O3, aka alumina) coned tweeters and/or midranges? If this is so, I think you are fortunate. I have heard(second hand) that these drivers are quite special. Used to see them a lot in the speaker parts catalogs I read(when I was "active" in the hobby), when they first came out. Were originally called Ceratec, then had to switch name to Accuton(or vice versa?), due to another company having dibs on the name. Lately, I have read a review of Kharma speakers(which I am under the impression use these drivers), and it was positively glowing. Supposedly very laid back and liquid, yet fully detailed. Please keep us informed of your reaction to the new speakers. Thanks

Best of luck with your new speakers Sedond. Please let us know of your impressions during and after break in. Joe.
