Keep in mind it also might be because of his encoder. I've not noticed any problems with bass or even trouble (Mp3 compression can sometimes distort treble slightly however) on most of my Mp3's, both that I have made, and that I have recieved from others. I use the Fraunhoffer codec on High Quality, works great. From everything that I've read and from my own tests, this is the highest quality MP3 encoder. It is however definately slower than other implimentations. So keep in mind with quality comes a drop in speed. I suggest doing your own tests with Mp3 and Mp2 files for qualtiy, don't assume that Mp3 isn't a good option based on one persons experience, especially with a lack of further testing. Anyways, just my 2 cents. :)
