When you take a badly recorded CD and then compress it even more for convience, there is no way anybody is going to hear what was recorded at the studio. Heck even if you do have one nicely recorded CD, the kids today have no way of knowing how it's suppose to sound. This happens every time a car passes by where all you hear is basically the bass with some of the other music in the background. It's too bad as I was sort of that way until my co-worker who is a big audiophile asked me to come to his house and listen to his stereo system. The first time I sat in his sweet spot he played a Parlophone vinyl Beatles album and it just blew me away. I felt as though the Fab Four was right in front of me.
Even a modest system will be better than what most kids use to listen.
