AdSeriatim, Digital recordings can have a higher dynamic range but to most people listening, this advantage is negligible. Vinyl enthusiasts will point out that it sounds "warmer", which is a subjective thing, but it's hard to argue once you've listened to it on a good system. Both mediums have their advantages. Digital is obviously easier to store and more mobile. Vinyl encapsulates a physicality that digital can't. It's tangible, you can hold the artwork in your hand, you can smell the vinyl and the jacket. Collectors will often point to this type of nostalgia -I'm one of them. That said, I have pretty extensive digital music library too. I understand how digital works and the benefits it provides. I also understand why people collect vinyl. I think it's analogous to the e-book vs. physical book thing. Do I read books/text electronically? Yes. But I still have a book shelf at home and I probably always will but only for my favorites. Record collecting is similar for me.

People that collect vinyl tend to be really in to sound and audio, to say that they "don't understand how digital audio works," is probably not accurate.
