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.

The ultra high bandwidth of the Norma amp, with this mids and highs horn drivers, specially the super horn tweeter, that have a very high bandwidth, up to 40khz, will be prominent to generate noise? or in fact it will be a good combination?

Thanks everybody.

No problem using this type of amp with your particular speakers! Anyhow, ultra-high bandwidth is not necessary for good sound! A Dynaco ST70 is bandwidth-limited by its OPTs - and still sounds excellent!

I’d use a SS amp on the woofer and a good tube amp (PP or SE) for the mids/tweeters. And an active x-over to split the signal between woofer and mid/high drivers. A Crown x-over will work fine!

Thanks for your feedback sir.. I'm wondering what's the point of this ultra high bandwidth amps, and the sound signature that they implement because this type of design... any thoughts?
