Got my Creative X-Fi XtreemeMusic about 2 weeks ago off of eBay, but I didn't have new speakers...so the other day I got my z5500's in and they're wonderful.
I know you audio guys will be disappointed in me, because I could have gotten higher quality studio-speakers...but they're a bit too much for me (considering I still live at home and I'm on a limited budget for myself), so these do just fine. Sadly I don't have the best setup for them (fronts on top of my desk, the rears are on the bottom shelf of my computer desk underneath me, on each side of the sub that's also down there, and the center is sitting on top of the sub below/in front of me), but it works nonetheless. Will post pics of it later.
