I think the OP is referencing using a “shielded power cord” vs a standard un shielded type PC.
I only use shielded PC on my DAC, CD and Streaming transports. This wa on the advice of Frank at Signal Cable.

In layman's terms, there is no such thing as digital power cord, heavy duty or otherwise. Power cords convey AC (60Hz sine-wave and analog).
