If a vinyl record is mastered from the original analog tapes it should sound much better than an over-compressed CD copy. My copy of "Death Magnetic" sounds much better on vinyl than the ear-bleeding CD of that album.
I suspect, however, that many records recorded today are recorded and processed digitally, even if they are then released on vinyl in addition to CD. Why and if they still sound better on vinyl is an interesting question. I have seen a thread on here discussing this a while ago. The consensus seemed to be that there are vinyl records processed digitally that sound spectacular, but I believe we're still talking recordings originally captured on an analog tape.
