One other thing--it's not always about sound quality or convenience! It's about the fun factor. Vinyl records, or the old shellac ones, are so delightfully tactile that the physical aspect really makes a difference. Records aren't perfect, but they definitely put the "play" back into playing records. Instead of scrolling and clicking, you get to get your hands in there and jam out.
Some folks just love old records, full stop. No need to justify it, no need to rationalize it. Unless you're an archivist there's no actual need to own a record player.
I can go get digital transfers or I can fire up my own record player and have fun. It's not always about stereo or about decreased surface noise; it's about great performances of great music. Nobody looks at
Broken Blossoms and gripes "Yeah, Lillian Gish wasted her talent by acting in these old silent pictures; she should've saved it for the talkies." And nobody looks at a 1940s classical album and says "Sir Thomas Beecham, knighted for his musical excellence, was a crap conductor because he didn't live in the stereo era and all we have are these old 78s."
And that is my 1912-1914 Edison and those are (real, as in 100 years old and not replica) 1920s jazz records on the bed. Still so much cheaper and more accessible than buying audiophile stuff, and built to last forever. Liking old music takes the audiophile stuff out of it--I can get all finicky about listening to it on fancy headphones with a tube preamp played off a FLAC file ripped by archivists at a museum and downloaded on a computer that costs more than my secondhand car, or I can go buy a cheap and unwanted windup phonograph off some classifieds ad and have music anywhere I want it. With maintenance it will be running 300 years from now easily. And it's not like I care about lossless file rates and stuff when my favorite tracks were recorded before they invented the microphone.
(I had Gershwin playing piano on the first ever recording of
Rhapsody in Blue. I have some of Rachmaninoff playing his own compositions. The performances outweigh the tin-can sound of the Victrola or the heavy proprietary discs for the Edison.)
One of my friends has a cheap portable electric bought from Goodwill and a Hello Kitty CD player. She has so much fun with that even though the audio isn't great. Just because fine audio exists doesn't invalidate the fun people are having with the old stuff, and doesn't mean that they're not worth enjoying or preserving as a viable option.
