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.
