Or...

Do you have a dedicated AC line so that it's not your fridge or anything else that is causing your sensitive DAC's to hickup?

Is your cable/antenna connected without being shielded from ground loops and such?

In my experience these things often stems from AC power issues or grounding problems. DAC's are sensitive to this. Have you had a lightning strike in the neighboorhood?
