The XMod from Creative is essentially a driverless external USB soundcard.  It has 2 modes, Crystalizer and CMSS-3D, the first of which attempts to fix the horrible things that happen when you compress audio and the second takes a basic 2 channel signal in interpolates a full surround signal.  If you have an ear that can tell what level compression was used in making an MP3, drop by t-break for a look at this little device.
“Plug, play and enjoy. Those three words basically describe the XMod by Creative- a small and stylish device that ‘enhances’ the quality of audio that you’re listening to. Packaged in small and slick black box, the XMod comes with a white pouch, a white USB cable and a white pair of earphones.”
