Advantages of beryllium?

It is indeed a dying market.

Any chance hipsters and headphone folks save some of it?

I'm front end of "Gen X."  There's a few of us...maybe waiting for estate sales and Goodwill drops when the heirs look at those ancient lightbulb radio thingies and giant speakers that don't look like soundbars and don't have wifi.

I’m a millennial hipster idiot. I bought Harbeth P3ESR and some Rega stuff if that counts as a start of saving it...

You're quite right about the dispersion and waterfall. They say a lot. That Magico is a stunning achievement. As JA said in the measurements for the 936, it's measurements wouldn't be out of place in an expensive speaker. That it costs just $4000 makes it an excellent value. And as we can see from the raw data, even Focals better stuff doesn't measure a whole lot better. 

So......

You're more than welcome to claim I'm arguing about speaker prices, though that really is a canard as well as intellectually dishonest. And you can argue JA has some slanted opinion, which I find every reviewer does. It's my job to discern that slant and interpret what his description might translate into through my ears. Regardless, his opinion has very little influence on how a computer measures a speaker. He cannot will the microphone to detect what isn't there. Another canard tossed out there on your part. Like what you like. Try sticking to facts you can actually back up though. 

kosst_amojan still waiting for you to point out a modern BE compression driver with better specs than TAD? But maybe all you had was a rude reply and ignorant comment.   And for the rest this maybe of interest http://www.audioxpress.com/article/Voice-Coil-Spotlight-The-Beryllium-Advantage
