So after testing with another USB DAC I'm not having intermittent popping issues. The only difference I can think of is the previous USB DAC is UAC2 (Amanero), which is also being powered by the Pi. With this other DAC it's UAC1 and USB is being powered by separate 5v supply. UAC2 fix didn't seem to fix pops with first DAC. Hrmmmm.
