One pair of Kimber Kable Select KS-1020 high end audio interconnect cables in a very good condition. KS-1020 is a state-of-the-art hybrid interconnect cable. Almost all technologies from the much more expensive reference cable KS-1030 are included in the KS-1020. The main difference between the KS-1020 and the KS-1030 is the wiring material. Due to the mix of silver and copper, the KS-1020 of cable technology is a hybrid cable. The signal is transferred by the world's best Black Pearl silver conductor. The advantages of the KS-1020 compared to the KS-1010 are a significantly reduced background noise, a more pronounced level of dynamic contrast and increased sensitivity for space and speech transmission. The length is 0,5 metre and they have the original WBT-0108 RCA connectors.On Jul-02-23 at 20:29:23 PDT, seller added the following information: Clarifying that the cable is 2M. I cut and pasted a description from another listing for a 0.5M cable, that is a typo. This is for a 2M cable.On Jul-07-23 at 05:39:22 PDT, seller added the following information: I have had a couple of questions regarding whether there is a serial number on the wood block. There is not. Not sure why there isn’t, but I am confident that they are authentic as I had one channel go out and I sent them to Kimber Kable and they were repaired and returned to me at no cost. One possible explanation is that I got the cables from a friend who was a tube dealer and would get lots of free and discounted gear from manufacturers, these may have been prototypes or some other production that was not sold to the general public.
