I have Beyerdynamic dt 990 premium 600 ohms. I use them for music, game, and movies. I know an Amp/Dac would be nice. Question is this: Has anyone tested the creative labs Sound blasterx G6, and if yes, how does it sound for audio quality ? I know that for gaming its ok, but for movie and music is it good ? Does it compare to Fiio e10k or any other Dac/Amp I keep hering about for about the same price ?
