Thank you! Contrary to audiophile opinion, linear power supply is not necessarily more linear than switched-mode one. Modern SMPS can be way more linear and in fact it's easier to make them linear.Standby power consumption <0.7W
The Chinese do not say how much it has in the on mode, but I speculate that no more than 7W. SMSL DO200 claims 5W and the devices are similar. In both devices, the aluminum housing remains cold (room temperature), I did not notice the heating of the devices.
