Anyone using a Class D amp w/ribbon tweeters?

I'm looking for some feedback about using a Class D amp 
with speakers that use ribbon tweeters. 

Anyone have any experience? How do they sound?

At least 3-4 years ago I was still believing that ribbon tweeters 
were not a good mix with Class D b/c of the sibilance it produced from the tweeters.

But now we have gone from ICE modules to NCore, Pascal, etc 
and other proprietary designs (Dig Amp Co) that may not be so bright, digital etch, etc

Anyone know about using more modern Class D amps with 
ribbon tweeters while having better control of the high frequencies?
Thanks
Gary

Thx, I’ve only heard of high marks for the bel canto Ref600 Monoblocks. And I have read that with each generational evolution with Class D, that we’re getting about a 10% jump in SQ pretty much across the boards, but particularly in improving the high end sibilance and listener fatigue. Apparently we are in the 3rd generation now (?).

Thx E. Which Class D amp are you using?

i was not familiar with the AMTs, looked them up. Look nice. 

Ive actually got a pair of Dali Helicon 400s with ribbon tweeters. I’m not sure about the the transformer with the ribbons, but these speakers were made around 2007.

Yeesh, this Merrill Class D monos are ridiculous! (aka awesome),
as described on the Merrill site, 

"Start with a 66 pound of Aircraft grade 6061 solid aluminum block. Delicately machine the chassis from this solid block isolation chambers to limit any sonic interference and minimize vibrations. Keep the walls 1 inches thick, to limit and absorb vibration. The result is a ..."

interesting what you say about the Bel Canto C5i (same for the C7?), 
that has been on my list of "all in one" units to pick up 
and play with as an extra system in another room. 
I was worried that it might have some upper end grain.

I listened to NuPrimes some years ago (2010), 
at that time, I wasn't too impressed, and unfortunately wrote them off.
Unfortunately b/c now apparently they have received many compliments. Will have to try them out again ....
