The XXL® Series 100 interconnect cable made of pure silver is based on the consequent development of the HPOCC® copper-technology. Massive HPOCC® silver conductors (2 x 0.65 mm) in a symmetric layout produce previously unheard-of brilliance and sonic fidelity. To suppress mechanical vibrations, five PE tubes were worked into the structure. A foil made of Teflon® provides a stable coating. An aluminium foil and a shielding of silver-plated wires protect the signal from high-frequency interference.
