Which is more accurate: digital or vinyl?

Hmm. How are you guys defining accuracy?

I see digital as inherently more precise in that vinyl results can vary much more widely I think.

I was under the impression of all things being equal. IOW, the best analog system and record, along with the best CD and player. Still a digital system can have a sonic characteristic that's not natural. I had a Luxman CD player years back that could not make anything sound real. Also a couple of other brands of CD players, or DAC's. I've heard plenty of bad sounding records, but they still somewhat sound more like the original source, than a bad sounding digital reproduction. After hearing some fairly bad digital reproductions, I find that I still hear that artificial reproduction in some pricey players. With analog, I never get fatigue, or those odd artifacts even from the worst records I've had. Bringing tolerances into it changes it some, but still I think vinyl has the edge.

The world is digital at the micro level but analog at the macro so there is no real answer to this question.

Stanwal, this statement does not make any sense! I believe it's the reverse - The world is analog at the micro level & digital at the macro level. As you ascend from the micro level to the macro level, you can quantize the info & make it digital (thereby losing as much as info as you deem fit depending the levels of quantization).
If the world is/was digital at the micro level, converting it to analog at the macro level means that we do not generate any new info. if the world is digital at the micro level it means that things exist only in discrete states. does this even make sense?
Think of Brownian motion - is it digital? I don't think so.....

i read "Redbook CD has a restricted top end compared to the best vinyl" and i can't really disagree. however, the question does not ask what is better, average digital or the best vinyl. a good hi res digital recording (96 and above) played on a system set up for it, is incredibly accurate and precise. way more so then any vinyl rig i've ever heard. since i haven't had an opportunity to listen to "the best" vinyl systems out there, i won't make a blanket statement here(and get pounced on =) ). i have listened to some pretty good ones though. i can say that when comparing the best i've heard from both sides, i think digital is more precise and accurate.

I think in the strict sense of the term digital is better, the best digital IMO trumps the best vinyl in this instance, one big reason for me is low frequency capability.
