Quite belated, I came across with this thread today.
I "intentionally" use four HiFi "integrated" amplifiers in my PC-DSP-based multichannel multi-driver multi-amplifier fully active stereo audio system.
You would please find my latest setup here and here.
The pros and merits of "HiFi integrated amplifiers" in DSP multichannel setup can be found here, here, and here.
This post would be of your reference for selection of "reasonable/affordable" small amplifier(s) driving tweeters and super-tweeters.
