My experience with CD treatments (I've tried several) is not that they improve the sound of a fresh disc - they are better at removing the "digital hash" on CD's that over time have become magnetized, dirty, or whatever. You can hear the hash. Also useful when you get the dreaded "can't read or no disc" error messages. Take out your treatment, apply to cd and no more error message. Happens every once in a while. I am still using George Lewis's product from years ago. I'm sure others have their favorites.
