I have just bought a pair of Sennheiser HD 598's. I have these connected to my Edirol UA-4FX Midi device (http://www.rolandus.com/products/pro...?ProductId=758). The sound is a little better than my onboard sound (Realtek HD), though only when I use the "Low Boost" and "High Boost" knobs to enhance the bass the treble. Anyway, I'm wondering if I use an actual sound card, like the Xonar ST, does anybody think I will hear much of an improvement?

Thanks.
