I've watched maybe half a dozen of this guy's YT blogs and his modus operanti appears to be to debunk everything!
Also I find a little disengenus, the most esteem 1960s engineer Ethan Winer is promoting his book, so take it with a pinch of salt.
I reckon throw more recording engineers into the hat and you'll get a different outcome each time.
Just my feedback on that video featuring Ethan Winer, all cables potentially are an LCR filter which differs depending on materials of construction and geometry. That is why different cables sound different, if you don’t hear the difference doesn’t make either of us right or wrong and I don't agree arguing it out until one becomes blue in the face. Ah, man you either accept it or don't, really it's no big deal!
