Ultra high bandwidth amps like Norma Revo IPA 140 with horns?

Hello to all, recently I discovered a very interesting amp from Italy, that have a circuit design focus on ultra high bandwidth, same as a Solution amp I think...

My question is: what will be the interaction of this type of design with horn speakers?

Especially with the ones that I'm planning to build, that have this high frequencies compression horn drivers and super horn tweeters.

Super horn tweeter http://www.loudspeakerdatabase.com/Fostex/T925A

Lot's of people tells me that the best amps for this drivers would be tubes, and class d for the woofers, but I'm wondering how would be the Norma powering everything, the woofer, mids and highs... the ultra high bandwidth of Norma it will be good for this drivers?

Many thanks, best regards to all.
