Hey, i recently purchased an Xonar D1 card for my computer, i have a very lousy cheap pair of speakers which i will not be able to use hear the difference in sound quality. So i would like to know what are the cheapest set of speakers i can upgrade to that will allow me to me to enjoy the new sound card. I would like the speakers to be of at least decent quality, i am no audiophile but do appreciate good sound quality, it just hasn't been a priority until now, Thank you.
