Finally, something we can agree on. Digital crossovers are seriously good, eliminating all sorts of problems in traditional passive crossover, simple amp configurations. Only thing holding me back is the considerable extra cost.
This is also a false conclusion. If it were true, then every IEM would demonstrate exceptional impulse response. Size does not necessarily make a driver faster or slower - there are other factors involved.
No, I literally posted the first high end speaker I found.

You are wrong regarding the structural resonances in ESL drivers - given the same size thickness of the perforated plates, the smaller one will be resonating at higher frequency(es) - thus less likely to be exited by music "overtones" than "fundamentals" of the larger drivers. A somewhat cheesy but effective (if implemented better) solution would be to use conductive textile mesh for stators - as used by Sennheiser in their Unipolar 2000 and 2002 electret headphones - FAR less "stator talk" than thin metal used by Stax. To those in possesion of Martin Logan ESLs : tap with a fingernail (or plastic pencil, to make 1000 % sure no electrical shock can occur ) on the stators (or better yet, have someone tapping on the stators while you are in the listening position ) with no music playing - whatever you will hear, SHOULD NOT BE THERE IN THE FIRST PLACE. It is true that ESL diaphragm does not have resonances - but it can not but follow the stators. Which DO have structural resonances ...- which are added to the original signal. This is the path a very well executed dynamic driver might be able to use to surpass the performance of ESLs.
I did mention the International audio Review's review of Acoustat vs Bowers & Wilkins speakers; it presented the same type of measurements, both for pulse and square wave. Acoustat (full range ESL ) was correct (with understandable limitations ), B&W was even worse than Utopia - going from positive and negative response in 20-20 kHz range 5 times ! As IAR is adamant about copyrights etc, I can not publish these decades old results; it remains the only audio publication that does not accept any advertising - and thus CAN publish whatever the real findings. But subscriptions are steep - 200$+/year. I only check a few snippets available for free online.
