i think all you have to do is plug it into a good soundcard and start recording from a good waveeditor. Thats pretty much it.

If you are still not satisfied with the sound quality, you can always play around with the EQ's in the editor, or record using a better sound card. If not, just take the set/demo and master it professionally or throw it through a good audio interface or compressor/etcetc...

hope that helps.
