Hi,
I haven't noticed a difference in the quality playing MP3s or
high-quality audio. Just make sure that you set the AHI driver to the
highest frequency possible. With MP3s though, you can't use the best
quality on a 68K system, except maybe on an 060.
I think that you may get some distortion also if you set the volume on
the SB all the way up through the MIXER program.
Cheers!
