I need help figuring out a external audio setup for $250 MAX. My hyperx clouds get crackling noises now and I feel it's my computer or the headphones themselves. I thought I might as well invest into a setup to replace my 3.5mm jack setup if it's either one. I was thinking of getting some hd 598's and a FiiO E10K. Is there a better setup I can get like maybe something that can power some dt-990-pros? Any help is appreciated.
