Interconnects, speaker wire, power cords. Ask the Cable Guys.

Ah, but they do!

CD players and DACs include DC supplies, so they contain rectifier diodes. While they do not draw as much current as power amps (and have as much opportunity to generate rectifier hash), they also contain high-frequency digital circuits. If any of the digital noise gets back through the power supplies and is radiated from the power cord, it will make the device sensitive to the type of power cord used within the context of the audio system. The device will also be sensitive to type of power cord if the internal power supplies do not completely block the RFI that comes in on the power cord.

In general, power cords are connection devices, filters, RFI radiators, and RFI receivers. Standard cords are designed to act as safe and reliable connection devices, with little or no design attention to the remaining three aspects of their behavior.
