I took my Atom HE with me for a few days. Due to location I was using an extension cord to power it.
Today I realised that if I walk bare feet the headphone cable gave me a light shock.
I tried again with it plugged into the wall plug. The problem was gone.
I assume it is an earthing thing with the extension cord or something.
As far as I can see and hear the HE is performing as expected still.
Is there a chance this could have damaged something if everything seems to be working?
