It depends on how you do it. i used a cobra '030 @40 mhz with 16 mb ram with a little cli script I found on aminet that brought up a requester to choose your mp3 and invoke lame to play it. I don't remember the settings for lame, but it sounded fine in 4 channels 8 bit stereo on the 1084. I also had Executive going as well. Thing is if I had a music player instead of the script to do it the cpu load doubled and there was no perceived improvement in quality.
