This is an old subject in many audio forum, but this dCS forum is sort of an ‘all you ever have wanted to ask about dCS products’ So her I go
I always use a pole checker to find the plus in a power chord. When the pole on the right side of the iec c14 plug is the hot one then it is usually right for most devices according to my dealer. It is not much of an effort and just to be sure… But how important is it for dCS gear with their high grade power supply and is that the correct way for dCS gear? If plugging the schuko the left or right way in the (European) wall outlet is a difference making thing to do, why doesn’t dCS put a mark on the power inlet so we know to plug the plug one or the other way?
