@Vakas you've asked a couple of times if you can use software with a DAC, I assume you mean the type of software that comes bundled with gaming based sound cards. The answer is no and this is the reason I use a creative G6 on my PC and a Zen 2 DAC for Hifi duties. The Zen 2 sounds fine on the PC but the creative software is useful to get the best gaming experience whether you use speakers or headphones
So do you just use the G6 on your PC or the Zen as well?
