As a technology and innovation professional (not in audio industry though) I’d venture to guess that the good makers evaluate many design options all the time and choose the ones that are reliable and work well and are in line with the "brand". I’d expect some R&D budget is there to help raise the bar over time as well else one gets left behind eventually.
IF some things are not seen as often as one might expect there is a good reason.
Anyone with enough knowledge and skill can join the game anytime and try out their own believed innovations. If they are truly better, then that’s the ticket to success, like with Nelson Pass and many others.
Or maybe all these smart folks making this stuff are all just trolls who don’t believe that these particular things make for better sounding gear or do so for good value. That’s an easy explanation. :^)
