This is Sommer's Newest and most advanced Instrument Cable!
This professional high end cable with the unique design is made of polished copper - the same as is used on industrial transformers. To further increase conductivity, the copper surface (OFC Class 6, purity level 99.9999 %) receives a final polish and a conductor insulation made of a special, surface-finished electro-insulation lacquer. The jacket is made of an extremely robust, adhesion-free and UV-resistant PVC.
The sound advantages of this design are extremely fast transmission capabilities (ideal for attacks), convincing mid ranges, popping deep basses, and an analytical transmission.
