I have a theory that we just aren’t measuring the right thingsThe question is fine except he's asking if the science is established and the correct response is "no, there's no evidence you can hear any difference in a properly conducted experiment" but that would fall foul of the text in the forum description:
"...this, and the other forums (other than the Sound Science forum), are DBT and ABX-free zones and posts about either will be moved or deleted"
so all he'll read is one-sided "typing" about the audio qualities of this or that metal.
I’m not too familiar with audio science, but if there was a repeatable way to measure “transient speeds” and “decay”, then I think the talk around cables can become more civilized. As the store owner of an IEM shop once told me, people can’t talk when they can’t agree on the rulers they measure with.
Also, as someone studying another scientific field, I think people use the word science with too much authority. Science changes too much, too fast.
