Provided he could show us measurable data and his subjective listening feedback (which I trust, since my taste in loudspeakers brought me to Ascend in the first place), then you bet I'd go for it.
I think that's just the thing... You can find some measurements of a multitude of tweeters and drivers on Zaphaudio. There's an Usher Be tweeter
here, he notes:
to date I've seen no real proof that any beryllium usage, either pure or heavily alloyed with other materials, is any better than aluminum or coated fabric. There's certainly a lot more to a tweeter than the chosen diaphragm material.
Hehe I don't want to sound like a broken record, but what is so special about Be tweeters? Is there really an advantage to 'Be' besides for marketing? Wilson use Titanium, Dynaudio soft dome, Thiel aluminum, etc... I don't think 'Be' is really that special for tweeter material... Some of the top 'high end' and very highly regarded tweeters are 'plain' soft dome!
