I had a Xonar sound card with my last computer, but after my upgrade I am using onboard sound from my MSI. My Superlux 668B just doesn't sound as good with the onboard. So, I thought about getting a cheap $50ish DAC/AMP. I was looking at the FIIO E10K which everyone seems to recommend or the Fosi Audio Q4. Actually it seems the new one is the K4. I like that the Fosi has bass and treble controls on the front plus more inputs. Although I will probably only use USB from my computer. I use my headphones mainly for gaming and TV/Movies. Any reason to go with the FIIO over the FOSI?
