This used to be the top of the range Interconnect from Kimber, and is now superceeded by KS 1036, which retails at $5,196.
It is a solid core hyperpure molecularly optimised Black Pearl, silver conductors terminated with WBT RCA connectors.
This is a bargain at $1,299 and in my opinion you will not get a better interconnect for the money. They are in excellent condition .
