It's all about your equipment. Compare vinyl to CDs on the absolute best equipment for each, and then you can make a statement about which one has the best potential sound, and even then it'll come down to personal preference.
Thirty years ago, I had the opportunity to compare them side by side because I didn't believe a salesman that vinyl sounded better. He sat me in a room with 6' electrostatic speakers and two 350W Class A amplifiers (Krells), and he set up a $7,000 (in 1988 $s) turntable ($4K of which was for the needle & toner arm) versus a $2,000 CD turntable and a $3,500 DAC, with everything wired with solid silver cabling. He pulled the same recording of Dvořák's Syphony 9 on virgin vinyl and CD, synched them, and switched back & forth and asked me which sounded more appealing to me. I learned two things that day: First, the vinyl sounded better to me. And second, I'll never own a system good enough that will showcase the full potential of vinyl.
Now granted, I don't know fully how technology on both the recording and listening ends have advanced in the last 30 years, but I'd venture to guess they're producing HD vinyl because vinyl can still hold its own if you have the money for it.
He used solid strand wire for the conductors? That is a terrible terrible thing.
