People are asking, so I'll answer: the card is not a *huge* improvement over the Audigy 2/4. I do notice the the better SNR... I can crank up my amp and have nary a hiss. I wasn't too impressed with the crystaliser, as it seems to only slightly boost the treble and bass... and on my already well balanced Klipsch SF1's, it sounded a little harsh. I wouldn't doubt the props reviewers have been giving crystaliser though... it was probably more intended for computer speakers. The new quazi-surround is certainly better than I've heard on any past Creative product, but no better than on the old Aureal cards... and it's still not appropiate for music.
