I honestly think it’s primarily because it’s retro, rather than being an audiophile - if it were the latter, you’d think it wouldn’t be so hard to find and download FLAC audio files for music - best combo of fidelity and convenience. Anecdotally, the few younger people I know who have a record player are artsy girls cultivating a certain aesthetic.
I want so badly for what you’re saying to be true, as someone who hoards uncompressed audio and has spent far far too much on headphones, speakers, and amps. Love me some high quality audio, but I really don’t see much discernment among my peers. More power to them, but my snobby ass wants a shift in consumer expectations so badly
