Has anyone had any personal experience with both or either of these sound cards? I have a mate who has the Z but to me his headphones sound quite boomy and the base is over emphasized with the out of the box settings. They both seem quite similar to one another so would like to hear some personal experiences if possible. Maybe some pro's and con's? I mostly game and listen to music with headphones. I'm definitely no audiophile but I'm not really liking the on board audio on my ranger vii.
