OK show us a power cord with two wire connection that has directionality advertised in the manufacturers POSTED docs/details. (not just an arrow on the wire.)
Some two wire powercords that have a figure 8 plug that plug into the back of low power devices such as cdp dacs ect. Can sound different if the figure 8 plug is turned around 180’. But that’s not directionality, it because the active v the neutral is fed into the mains transformer differently, inner winding v outer winding. A FUSE DOES NONE OF THIS!!!! It’s a 1/2" piece of resistance wire!!!!
Like I said Forest v Trees v geoffkait .
I relay my baton over to almarg/mapman, I’m sick of of this voodoo s**t.
