Using with Edifier 880DB speakers

If you hook this up you gotta use a "Optical Cable" from your PC for gaming the USB passthrough was kinda annoying the sound was. I also own IFI Zen Dac 3 which would be perfect but it doesn't have a Optical port where I can use it for PC gaming. You might have to turn the treble down a notch or two have mine on -1. Playing Borderland 4 with it currently. For Headphone use I don't recommend this at all get a IFI Zen Dac V3 it doesn't have the punch that Amp does.
