All cables are possible resonators.

The common-mode (also normal-mode in some cases) noise is partially reflected by impedance changes at the connectors. Depending on how bad the mismatch and background noise, any given cable can support standing waves that affect the audio through intermodulation in some other part of the system.

People who build communication satellites understand this. Some few audio cable makers also understand it. Oyaide makes carbon-fiber AC outlet covers to provide damping of the electric field components of standing waves on the power cords.
