edit: ah the video itself is made as a joke. you got me good, consider me bamboozled, well played. it's a really good satirical piece as well, poking fun at various marketing blurb that audiophiles routinely fall for!
note: i know OP is joking, this is in response to the video itself
watched the video, and maybe i'm just a pleb who doesn't (needlessly) spend thousands of dollars, but i thought there wasn't much difference in sound quality, and even then to the laymen the comparison is simply not convincing since he isn't playing the exact same samples in his comparisons.
in addition, why does he talk about how they "inspect the raw copper" and why he and the company feels the need to compare copper to olive oil? also the talk about "first extrusion being the best"?
i'm no expert, but just a quick search on the internet tells me extrusion is more related to shaping the metal rather than changing the metallurgy of the metal itself. also last i checked, olive oil is waaay different from copper?? and aren't there ways to purify or refine the raw copper ore, so the purity of the copper ore is irrelevant?
