Wow, so much effort into this. Thank you so much.

That is true. Wow, with so much measurement and graphs, this can be a R&D paper! Thank you for sharing!

Fantastic write-up!

(and Jon Anderson). LMAO. Having seen Yes about a dozen times, I have to agree that there are times his vocals are like fingernails on a chalkboard. But the good far outweighs the bad. Thanks for an unexpected and needed laugh during these times.

Nice article! A question I have: what should I expect from the impulse measurement? I sort of get the speed part, but what's the specific damping difference between this and xelento? Thanks!

There are three parts to the impulse response: the rise (how quickly the overall system responds to the kick), the fall (how quickly the amplitude drops back to zero) and the settle (because usually the fall is messy and bouncy). The settle time is affected by the damping in the system, which is where the theoretical advantage of Beryllium comes in (because it's stiff and has good damping properties: https://materion.com/-/media/files/...acoustic-properties-of-beryllium_materion.pdf). What you should expect, in an ideal world, is a dirac delta function - a single sharp spike with no wobbles behind it. It's always tough to know what sort of errors would be acceptable, or completely inaudible (that would vary from individual to individual anyway). But it seems humans are fairly sensitive to timing differences, so it's nice to see any technical signal measurement that gets closer to reality.

I had to laugh when I read somebody cut his ear. I have the a8000 next to me right now... and I really wonder how this is even possible In theory. I find them very well rounded, no issue there whatsoever. Thanks for the review.

Thanks for the review. Going to take a look at these.
