I understand what you are saying and it makes sense that there would be some advancement, even if small, in SOTA since then. But the advancements might have been so small that they aren't significantly audible to the average person in the average room.No, and I'm not even disagreeing--I have no idea!
But I expect evidence for a SOTA claim in 2025 to be more recent than two popes ago![]()
Perhaps the biggest advancement since then has been in bringing measured speaker excellence down far lower on the price curve rather than easily audible, outright high end speaker design improvements. That along with significant advancements in dsp that, relatively cheaply, improve sound for the average user and average room.
And ASR has played a significant role in highlighting that measured improvement to more designers and manufacturers. And consumers too, of course.
