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

I am using ICEpower 25 ASP based mono blocks. One under each speaker. Literally. :) 

My ribbons are from Mundorf. Sound fabulous, but electrically VERY different than a ribbon.

Ribbons tend to be very low impedance, and need a matching transformer.

AMT's have no need for a transformer, and are almost purely resistors (relative to most drivers).

I’m using Class D with top-end AMTs, no problem at all, though technically not ribbons. 

If you are using a true-ribbon they tend to have transformers, I'd be curious to know how the Class D work with those. AMTs are nearly purely resistive, so I may have better luck. :) 

Best,
