I have and use foobar. It's a great player. I was merely quoting the foobar people to help the new Head-Fiers. I don't think it's fair to lead them to believe that they're going to hear big radical differences. Look at the first word of foobar's answer. If you hear a difference, well that's great, because it really is all about what sounds best to you. I got on this kick when I started to blind test my friends when they came over. Next thing you know it was, "you try it". I made 3 playlists of the same songs. (They both had a couple different mp3's hidden inside with the flacs.) I loaded the playlists into foobar, mediamonkey and xmplay. No one could get it consistently right. Certain mp3's got picked most of the time. Some not. But nobody could tell which software was playing. At first I was bummed ('cuz I'm Superman you know =^) Now I'm enjoying my music more because I'm not trying to hear things I can't. Try telling the difference when you don't know what's playing. You might be surprised; I was.
Again, look at the second word of foobar's answer.
Justin, I don't think you're in any position to doubt what people can or cannot hear, so quit it.
