X-Fi Xtreme Music user here. Using it with 4-way chapalang stereo speaker right now. Will upgrade to Z5500 soon (used to use Creative S750). I used Vista for a bit, now back to XP. No driver/apps problem in Vista with YouP Pax. Will use Vista back once i build my new PC.

Well the S750 have some known reliability issues, in which the amp will blow up after a year or so but depends, it can be months or it won't blow up at all. Mine blew up exactly a year and a week after i bought it. I can't really have it repaired because i'm nowhere near KL, so i borrowed my bro-in-law's speaker for a while until now. Using this Z-5500 for a week already, i think it's as good as the S750, maybe the satellite lack a tweeter but i can't really differentiate the difference. The bass is not boomy at all. And 5.1 is quite enough in my room, 7.1 is too messy and cramped.

Oh and the Z-5500 will auto off if it overheats (which i never faced yet). Good safety feature i must say.
