[citation][nom]Thunderfox[/nom]How can someone as old as Niel Young have the hearing capacity to distinguish between an MP3 and anything else? Is there a difference between MP3 and CD? Yes, but that is the price of convenience, and it's not like there aren't already better formats than MP3 anyway. Mp3 is desirable because everything can play it and it has no DRM.Is there a difference between a CD and DSD or SACD or whatever newfangled formats may arise? A bit perhaps, but most people would be hard pressed to notice it. And besides, how much music over the last few decades was mastered digitally? Was their equipment comperable to the quality of DSD? If not, get ready to buy all your music in new remastered DSD editions again.[/citation]
To the first question, it's more a matter of training than age. I can hear the difference (CD / compressed) fairly clearly, and I don't spend as much time listening to music as Neil Young does.
To "Is there a difference between a CD and DSD or SACD or whatever newfangled formats may arise?" once again it's a question of experience and of individual physical ability. SACD simply encodes more of the music than CD, and CD more than a lossy MP3 file.
You are right, it is the price of convenience. But, to push an analogy too far, some of us are content to eat fast food, some will take the trouble to cook, and some save up to be able to experience gourmet restaurants.
My wife can't hear the difference between good speakers and my TV. I, personally, can tell the difference in my studio headphones between sound that comes from my sound card and sound that was converted and amplified by my headphone amp. The headphone amp lets the music breathe a little more easily.
Some people can't tell the difference; for others it becomes a tradeoff between convenience, price, and quality. No-one will say that MP3s should be eliminated. But it might actually make sense to have high-quality versions available for those who prefer them. And the higher the quality of the master, the better everything down the line can be.
