Hello , Not rly familiar with sound stuff , i had a sound blaster z for a few years which did a pretty good job sound wise the only down side was it was picking up coil whine through the headset and mic which started to get pretty annoying and i was looking of buying a dac/amp to get rid of it any recommendations ? was looking at , Creative Sound Card External USB Sound Blaster X3 7.1 Channel which it says they output the same db which im assuming is how loud they ll sound , unless i can get rid of the coil whine which after some research doesnt rly look possible , thanks
