Machine aging

The burn—in time of Draco DACs is one week: Standby or Powered on 24/7 (300 hours), you will get the best performance after the enough aging hours.

Connecting RCA or XLR output simultaneously is not recommended, it will degrade the sound quality because they are shared. Even if the downstream equipment is on/off, the output signal will still be transmitted to the input stage of the downstream device.

If possible, please use the XLR output. As a true balanced DAC, the XLR output of Draco will be more superior.
