It's never a good sign when an audio-band opamp is showing RF instability. Literally, the amp just needs a pair of small caps at the input to shunt any RF coming in. Having said that, what you may be hearing is noise coming through USB from a computer.If you like the amp, try using some shielded cables from the Xonar to the headphone amp. Also, if you have an optical digital out, try using that into a different DAC for good isolation.
