How do you know that? In
2001, 54 wine experts, guys who presumably are sure they can tell the difference between wines, were given two wines to taste, one in a fancy bottle and one in a plain bottle. 40 said the one in the fancy bottle was worth drinking, while only 12 said the one in the plain bottle was worth drinking. Except,
they were both the same wine. People taste what they expect to taste, and hear what they expect to hear. Which is totally fine; even if your preference for vinyl/CD over mp3/AAC is a complete delusion, if that delusion makes you happy, I've got no beef with that. However, if you're going to be disparaging the aural capabilities of the rest of us, then you better have made sure that you've tested yourself first. Otherwise, I have no reason believe that your high horse is made of bone and muscle rather than smoke and mirrors. 256kbps AAC files (what iTunes provides, and thus, exactly "what the vast majority of people use") are indistinguishable from the original for that vast majority. Maybe when you test yourself, you'll prove that you *can* distinguish them, but that makes *you* the rare one. And the odds are against it. Just like wine-tasting, or driving (where the majority of people think that they're in the minority of "good drivers"), a lot more people *think* they have exceptional ears than actually do. Despite the technical jargon, an ABX test is really pretty simple. You take a .wav file, compress it (using iTunes's 256kbps AAC, for example), then decompress it back to .wav. Then, using a program like WinABX (a bit hard to find at the moment, but I can hook you up), you load up both the original .wav and your compressed version. It randomly picks one of the versions, calls it "X", and you have to tell whether it's the original or the compressed version. You repeat the trial 10 times or so to reduce the probability that you're just guessing correctly, and that's it. I've been sure I could tell the difference between versions, until I loaded them into the ABX tester, when suddenly the difference disappeared. Discovering your ears aren't as good as you thought can be a bit humbling, but better to know now than a year from now after you've wasted thousands of dollars in audiophile equipment/recordings, right? Or, if you *can* tell the difference, then you can brag with full authority and confidence! It's a can't-lose proposition. Neil
