Hmm, out of curiosity (again):
Given that both a vinyl LP and a CD (I'm going to leave SACDs out for now) are in Mint condition, the same would hold true? I mean, I know that vinyl has a lot of drawbacks and all (portability being the biggest of them... does that count as a pun, or was that just a bad joke?), but there're ways to remove all the dirt and grit on the surface of a vinyl disc, right? So the only reason that vinyl sounds "worse than a CD" is because of the fact that grit gets in between the grooves and causes pops and crackles? And also: the reason that there are a lot of people (particularly here on Head-Fi) that have a thing for vinyl is because they're generally well-mastered, and not because the physical medium is really any better than CDs?
Sorry for the persistence. It's just that I'm debating whether or not to invest in a proper turntable (my aunt has one that I could get at a discount, though from what I can gather it's not in very good condition). If CDs, well-mastered ones at that, really are better than vinyl on the whole, then I can scrap those plans and invest the money in a good receiver and amp/DAC, maybe new cans :)
