Pure Insanity !! I remember being a dealer years ago and even maybe 15 +years ago, Kimber had a 6ft pr of speaker cables the black pearl $15k
but they sold at least 10 pair to the ultra rich .Even if I had money to burn I would never consider that ,especially knowing the markup on cables can be 6x to 60 x the markup some companies think their time is worth $300 an hour.
Personally I build my own using the best UP-OCC -0 Crystal Copper ultra light Teflon dielectric , useonly pure Copper or Silver Connectors and top grade solder
you can then Compete with cables at least 6x as expensive ,they can keep the fancy covering its the sound that counts !!
