Hey guys i recently got an Asus Xonar STX sound card to pair it up with my SP2500 because while I was using my onboard audio I could feel as if the speakers could do so much more. But when I hooked up the sound card it seemed like there was no difference at all. Am i doing something wrong? I have the latest drivers for the soundcard, but the bass and clarity still seems to be lacking. Also what headset would be good to pair up with it around the $200 price range? Any suggestions would be much appreciated.
