Hey guys, so I purchased the PC37x's awhile ago and love the sound quality, especially since this is my first pair of open back headphones. However, any audio device that I plug into my computer suffers from pretty frequent crackling and popping noises. I asked a few other places, and have been told that I might need an AMP/DAC to solve this problem. Would an AMP/DAC actually solve this problem, and if so, which one would be ideal for the PC37x? Sorry if any of this is obvious, I recently built my first pc and don't have much knowledge on headpones, amps, etc.
