Kirk McElhearn writes about Apple software, iTunes and Apple Music, audio quality, scanners, and e-books.
HN commenters cite his posts on audio fidelity, including his argument that vinyl does not sound better than CDs, and his older iTunes tips.
If you care about audio fidelity, as opposed to the "vinyl-ness" of the sound, vinyl is worse:

Obviously, if you want the most vinyl sound around, vinyl is the only way to get that. However, if you want maximum fidelity to the original audio source, vinyl has inherent limitations later formats do not.
A problem that Apple used to understand, if you look at their keyboard USB cords:

I guess the USB-C plug is too small for gimmicks like this, though. Would've been nice to distinguish between USB-C and TB 3.1.
A few years back the iTunes store used to sell pamphlets on things like how-tos as PDFs, but they seem to have gone now.
