I've been thinking about your question. I suppose one appeal for me is that I understand how vinyl works. Putting a CD in isn't that much different from hitting Play on your MP3 player: you queue up your song, hit play, and music just happens behind the scenes, you can't watch it. But with vinyl, you can see it in action. I occasionally just sit there and watch the needle and cartridge and tone arm move across the surface of the record, imagining how the tiny vibrations of the needle are transformed into electrical amplitude, increased by the amp and played out of speakers. It's fun and, today, novel to be able to understand a whole system like that and observe each part doing its task.
