@rastus: for what I am aware, the transformers list for priority (best is first) should be:

R-core
Toroidal
IE isolated
Switching

I saw many audio devices especially the high-end ones, its supply unit went with toroidal transformer so the IE ones are lesser in the sense of high quality audio.

Some other experiments proved that a battery like this https://www.amazon.com/ExpertPower-EXP6 ... h-keywords that feeds a dc-dc step down board to supply a very good linear / purity source for the Pi. This is surely better the case of EI transformer.

Hi guys,

in the end it does not matter how you get the best (most noiseless) power. Someone has design a device in order to make SPS behave well:

Well thought out
