I will be using my system to game on headphones about 40% of the time and listening to music on my headphones 60% of the time. 3d sound on the headphones seems like a really cool idea that I'd like to get into, in which case the x-fi comes to mind. However I hear that music can sound like pure ass, in terms of fidelity, and detail. I also detest the cost 130 for basic model! I was wondering it there was any 1 single card that can handle both hi-fi stereo music, and 3d positional audio. That or a cheap yet good 3d positional soundcard for headphones, that i can line-in with an E-mu 0404.
