Creative recently came out with a range of sound cards that carry the X-FI (xtreme fidelity) moniker. Their major claim is that they're able to "restore" 16-bit audio to 24-bit audio using their "crystalizer" software. As far as I know, once you lose audio data, you can't get it or fake it, but the press is going ga-ga for it. What do all of you audiophiles think of this? Worth its salt? Discuss.
