The OP has an interesting query here. Can't say I've ever seen or heard of elevated audio cables before.
Wire management is handled using cable trays. Your local utility uses miles of cable (and cable trays or underground conduit) in every substation for SCADA control and other sensitive switching control.
The electrons know where to go... I'd be more concerned about external EMF than cable vibration at miniscule voltage potential.
