I use a delfina lite card, and to be honest i reckon if you have any other means to play mp3, use them instead. The delfinampeg.device is buggy, quality seems to be pretty bad, and it refuses to play mp3s at certain bitrates/frequencies. If you need a soundcard because your native sound is dead or something then it will do that (although its expensive for just that), if you play to use it for anything other than playing 16-bit samples then dont expect much, the days when amigas where great musicians tools are long gone.
