So, what DAC/AMP would you suggest for around 200$ with an optical input?
P.S My headphone are gonna be the Beyerdynamic DT250-80ohm.
Why not just try the DT250 80-Ohm headphones plugged straight into the Xonar DG sound card first.
If there is still a buzy, then look into buying a external DAC/amp.
Did you "disable" the motherboard's on-board audio (in the BIOS)?
Tried the Xonar Unified Drivers" from Brainbit?
Move the Xonar DG to a different PCI slot?
