That's not being old fashioned but having sense of quality. No digital format whatsoever can compete with vinyl when it comes to sound quality (unless the record player is really bad and creates distortion, unstable speed etc.). That's not just my personal taste but a physical fact; the resolution of vinyl is infinite (since it's analog) which no digital format can compete with since it's limited to, well, whatever resolution it has.
On a lot of tracks the difference may be hard to hear (very easy with other tracks) but in most cases you can feel difference.
When I got Etnica's - "Trip Tonight" on vinyl ("Hell's Kitchen", 2001) it was a whole new experience; I already liked the track but it suddenly had totally new level of vibrancy, dynamics and depth and the mp3 version sounded completely flat in comparison.
That doesn't mean that music played digitally are necessarily bad at all (I'm very fond of my cd player and cd's and playing mp3s through my stereo works nicely too, although I'm very disappointed with the crappy sound quality of Ipod - high-end earphones just exposes the flaws even more.) Unfortunately the production of new music is getting worse and worse due to most new music is now being produced to be match crappy systems (most portable mp3 players, cellphones, radios, cheap in-ear phones, build-in laptop speakers etc.) that can't handle dynamics.
