I can hear the difference. I did a test like that in my home setup and in my car when I had my 860 which played mp3s. The dynamic range gives it away every time. Not to mention you can hear it in the cymbals.Funny, double blind tests would disagree with you. It's been done, MP3 at 192kbps vs. original source CD, none of the participants could identify if it were an mp3 or CD at a rate better than that of pure chance.
