You do realize Jay Iyagi is a kid, right? I doubt he had even turned 20 when he started his channel.
Here's an old video where he's trying to articulate the difference in sound signatures of 2 speakers...not bad for a kid actually. I used to have a double impact sometime ago ( know what he's trying to get at).

Jay Iyagi and that Zero Fidelity dude are the guys i trust, when they're trying to articulate/describe the sound signature of something....and yeah, if some kid wants to clickbait a bit, i'll forgive him, whatever...
There are some other reviewer clowns who try to describe the sound of an amp, but, essentially he's describing the sound of a speaker, yada yada...you'd be lost if you listened to some chaos clowns.
I used to like Jay of Jay's Iyagi but he's turned very much to clickbait titles and a bit of plumping for audio stuff that has turned me off.
