The YouTube guy is an air-head.  He's even got a stupid haircut - bumped into a buzz-saw and a can of axle grease.
He's not saying anything that wasn't already said by hundreds of guys old enough to be his grand dad.  He imagines he's the first person to think of this.
He doesn't talk about the sound at all.
Total waste of six minutes listening to him.
He has a $200. Uturn turntable with a $70. Ortofon om5e cartridge. Yes, his vinyl sucks. When I go to my friend's house and listen to his Insignia system, I think stereo sucks!
Once you get to a high-end digital system like Grim Audio MU1 streamer + Mola Mola Tambaqui DAC there is unfortunately no more role for Vinyl in my setup. I say unfortunately because I wanted Vinyl to win... I therefore organized a session with 3 (musicophiles but not audiophiles) friends and did a blind test.  To make things even harder I played my very best Japanese pressings...  
Digital gave them more pleasure. One of the 3 friends is a well-known baroque orchestra conductor: he found Digital to have more realism in terms of timbres, staccato/legato, dynamics. Ditto for percussions which he found more realistic. RIP Vinyl for me, but VERY respectful for all the others who love it.  My amazing PTP model 12 (Lenco-based) with Schick 12” arm and Lyra Delos cartridge is officially looking for a new home... 😎

If you think vinyl sounds better, then your brain will make it so and it will sound better to you. Vinyl does sound better, to those who think it does.

If his kit was improved he would like it more. He buys a spitfire and says he doesn't like e-types. Ok matey
