I believe that a computer makes a better audio source than a CD. Quality isn't really better, but it is easier to get to what you want. Thus, I watch my TV and listen to my music all from my computer. TV is clearer on-screen than on a normal TV, too. It's a pretty good deal really. I have made music before, but it wasn't exactly my best art.
My computer does do pretty heavy stereo duty. To be honest, what I bought is for my car instead of my comp this time...but I can't resist trying it on my comp first.
