Kevin wants to know if HD audio is like HD video as far as clarity and resolution. He thinks that with cheap headphones, nobody is really going to tell the difference. So is it worth it? Leo says that David Pogue stated that HD audio is 'snake oil,' and it takes some training to hear the differences.
The real question isn't whether HD or CD quality is better than MP3. It's the fact that HD audio is uncompressed. Kevin would have to learn how to hear it the differences of HD audio and once he would hear it, he won't hear it any other way. Leo's point of view is, if he's going to buy something, why not pay a little extra and get it as close to the original studio master recording as he can?
