The offer of the Ultra Reference line is a combination for demanding owners of refined audio systems. The cables within the series are partly made of silver-plated copper and conductors of OCC copper and FEP dielectric. The cables are shielded with a silver-plated braid in the Multi-Shields system, and most of them are terminated with proprietary plugs that have been subjected to the double rhodium plating technology in the DCP process. Most cables from the Ultra Reference series in the standard version are equipped with antistatic smart couplers by Acoustics Points, while for the premium and luxury versions additional filters are provided. POM-C AP50 material provides excellent protection against static electrical changes.
