Does anyone else here have this combination? I'm asking because I can't seem to get a good balance in the settings. I'm getting a bit of distortion in the bass when I turn up CMSS, and I'm not sure if the Crystalizer is having any (good) effect. If there are some general guidelines that I should follow, I'll listen, but I'm really hoping someone else has the X-Fi with the Logitech Z-2300 and tell me what all they've changed to get the best sound. I'm refering to Entertainment Mode, but if you want to include gaming mode, that would be cool too. Thanks guys.
