Designing an amp specific to the speakers it is driving is a great idea. Remember Acoustats? They made an amplifier, the TransNova 200, that would drive their very difficult speakers. 1981, I believe.
My Acoustic Research LST speakers, now almost 50 years old, are still singing beautifully in my second system (yes, they've needed some repairs over the years). If they had internal amps... not so much, I think.
Isn't it true that pro speakers are internally amped primarily for ease of setup? A speakON and a power cord and you're good. Can you imagine the expense and hassle of miles of speaker cable? Not to mention the mess.
Seems like a good excuse to insert a plug for my dream speakers and their dedicated amplifiers. Yes, Darth Speaker and Mono-Me, but wow. Hear them if you can.
Peace.
