If I spent 15k, got 105db efficiency, low distortion, dynamics that would make most of the standard box Magico’s sound broken, I might be pretty happy. Especially if people were comparing them to speakers over 250k.

I completely agree. But at $15K you deserve constant and controlled directivity as well (north of 500Hz or so)

That's a MUCH more difficult pie to slice and takes serious chops, serious engineering and serious resources particularly with research and time. You know the specifics of what to look for I'm sure and
most of the designs discussed on AC don't fit that paradigm. But some do...
Best,
