Which way should the mains cable be plugged in?
Answered
A question about the correct connection of the mains cable. On old devices with transformer power supplies, you can measure the voltage at the housing vs. earth. If I turn the mains plug 180 degrees in Europe, I have a worse sound if the AC voltage between the housing and earth is higher and I have a better sound if I measure a lower voltage. This type of measurement does not work for devices with a switching power supply without a real transformer. The Node is such a device. I have found out which way round the mains plug has to be so that it sounds better to me. I would like to know whether my subjective impression corresponds to the correct recommendation. So my question is, on which side of the two-core Euro cable should the "hot" wire be regarding the Node? Looking from the back, left or right?

Hi Heinz
You correctly noted the NODE has a switch mode power supply. By definition this objectively means power is ‘corrected’ as it is drawn and there is not specific left or right ‘hot wire’.

There is no correct way but I agree with you that swapping the lead round can have an effect on SMPS. Have posted in this very forum to try he lead the other way to eliminate noise.
