And I'm being a pedantic prick so ignore me 😀
Regarding "progress..." If electrostats were really old these days, maybe some of these new planars and dynamics that came around as a result of this progress would actually sound better than the old electrostats. But that hasn't been the case in my experience. IMO this progress malarkey is just another FOTM, with the big revelation being - drumroll please - that "neutral" doesn't mean "bright as fuck!" Wow, we've come so far!
But, seeing more electrostatics, or cool new things like RAAL - and they've got a new circumaural headphone announced too - is actually interesting, and the more good headphones out there, the better. Besides somebody needs to light a fire under Stax's ass and what better way than actual competition. Maybe this way they'll stop making headphones with headbands that crack, ergonomics not designed for human heads, amps that are defective by design, or tuning that's best served as an advertisement for EQ plugins. And if not, well other people will make stats too.
