It sound "better" because bass and trebles are overloaded-at the expense of midrange.
I finally hooked up hitachi tape deck at home and played old tapes(from up to 10-12 years ago)-copied from LP's on good equipment.
They are not as "crispy" as CD's, but they more "musical" with amazing imaging and ambience.
Sound quality is not limited only by frequency response. Road noise can hide imperfections in music, but it will not hide lack of ambience, even if 20-20khz are reproduced.

Because the process is not perfect you will notice a degradation in the audio quality.
When you convert the MPEG compressed audio back to an uncompressed bit stream (.WAV) format there is no way to put the information back in. There might be something out there that might help interpolate some of the information, but I have never seen such a program.
Basically think of MP3 as reducing the color count in a picture where there are certain tones that your eye can not see. Once you remove that information, it is gone.

And that's why there's still a bunch of people out there still swear by LPs.
Some people just have more sensitive ears and swear they can hear the difference. I think it's just a matter of taste, coz eventually you want to "feel" good by listening to music. And that's why when it comes to audio, there's many many different brands/models and these different brands/models vary greatly in prices.
I don't know if this has happened to you but whenever i've upgraded my audio stuff and I ask my gf if she hears any difference, she would say somthing like, "it's louder?"
