Sommer Onyx 2025 Dual mono (Stereo) cable

Twin Mono, Un-balanced, 2 x 1 Core and Screen, Copper Wire Cores, Copper Wire Screen


The twin cable...


....is similar in construction and quality to the TRICONE MKII, but a little thinner due to the twin-construction. It is suitable for the fabrication of HiFi-cables, adapters and for permanent installation. And it fits almost all jack and RCA plugs. The SC-ONYX can be split at the centre of the cable. Each wire has its own copper spiral shielding and is equipped with a thick jacket. The insulation is identified in either white or red.



  • Very flexible due to the use of fine individual stranding
  • Every conductor is insulated and individually shielded with copper spiral shielding
  • Manual separation of the cable is easy
