I really think that the rise in vinyl sales can be attributed to more than just "audiophiles". It's also about packaging and their popularity in live hip-hop and even electronic music, both of which are increasingly popular among the largest groups of music purchasers.
I really do think this is what a lot of people miss when purchasing music online or even on CD: things like album notes, lyrics, and album art.
Honestly, I buy most of my stuff on CD. But I have most of my favorite albums on vinyl because I would rather have the "full package" for my collection than just a shiny disc and a 4"x4" piece of paper.
Sound quality isn't EVERYTHING.
