Here you are… the super duper power cable, dubbed as “May Be the Most Sophisticated Power Cord and Connectors in the World”. It costs $1800, triple+ than the $500 Denon Ethernet cable. Hilarious, click to its homepage (and don’t forget to look at the features list).

The reason these cables are so expensive would be attributed to the shielding and lack of interference for specialized visual and audio technicians. For example in the music industry interference from a cable can be make or break when producing a track.
