The problem is not that it does not work. It's just a bit imprecise. With the same MP3 files, if I play them out of a MP3 compatible diskman out of its line out, the sound it very crisp. Out of the headphone jack, I get the same "almost good" effect. Out of the computer (still same MP3 files), no problem whatsover.

Anyone knows what is the impedence of the line in of the Audiobytes' amp?
