It's funny people are still learning this, but I guess some are younger. I have hundreds of CDs I started buying about 1992 or 1993 and did a big project at one point making MP3s and early on in the iTunes/iPod era they found their way into iTunes. I started playing around with MP3 Layer 2 and then Layer 3 around 1995-1996, but at that time it was still prohibitive to try and store your whole collection as hard drive…
Vinyl isn't making a comeback because of mastering or fidelity issues. It's making a comeback because people like the ritual of putting a disc on a platter and having to focus on listening to it. It's a different form of engagement with the music than the endless, pre-curated stream of singles that are the default way of using streaming services.
It's about focusing on the listening, but in some cases many albums are getting better masters on vinyl than any other format. It's technically stupid but it is what it is.
What's so stupid about the audiophile aspect of vinyl is most of the new ones I bought are dirty. You have to clean them right out of the package if you want them to sound good. Something is very sloppy about production right now. CDs are about a million times more robust.
