Rhodium Rh45 plated pure copper plugs for optimal conductivity and contact strength.
 
Large cross-section OFC - 4N conductors with STAR structure: 6 concentric multi-stranded conductors around a central solid core conductor for perfect signal transfer and velocity.
 
Double shielding for perfect isolation from surrounding electromagnetic and radio radiation (RFI & EMI): optimal cotton fibre for reducing micro-vibrations internally, peripheral insulation made of paper and thick PVC foil externally.
 
Conductors directly fixed to the plugs of the connectors without soldering tin, minimising impedance and ensuring perfect current transfer.
