I suppose I should have also mentioned that I am running a P-IV at 1152xsomething, and a whole bunch of patches to take stuff out of Chip RAM. It probably makes a little difference. As well, the library used to decode the MP3 in the first place probably makes a difference. I am not certain which I am using, most likely whatever AmigAMP uses by default. Again, high bit-rates ain't cuttin' it on my system. 128kbps is the highest I can reliably play whilst doing other things. 192kbps stutters sporadically, and anything higher you can forget about altogether.
