So far I had none of the reported problems. The only issue that scarred me just after setting up my desktop gear with the DA8 was a very faint noise from the HP amp that was independent of the volume control. Then I figured the noise was caused by a DECT wireless telephone set cradle (the transceiver base) that I put on top of the DAC. I put the phone set away from the DA8 and the problem was solved. DECT phones, like cellphones, are very strong EMI (Electromagnetic Interference) and RFI (Radio Frequency Interference) sources. It looks like, despite the very thick aluminum case that should act as an EMI/RFI shield, the DA8 is sensitive to interference. Aluminum is a good electrical shield but not a good magnetic shield. May be the noise was conducted by magnetic fields from the phone cradle.
Slingshot80, try to move the DA8 to a different position to see if it affects the problem. May be other devices close to it are inducting interference.
