Further improvement of copper material to replace PCOCC
PC-Triple C is a new material produced by combining high-purity copper with a special forging method and annealing (heat treatment), and was developed as a conductor to replace PCOCC, which has been discontinued. Through this manufacturing process, the crystal grains are continuously connected, and it is a remarkable material that achieves high sound quality and high durability while minimizing signal transmission loss.
AndFidelix and Amtrans jointly developed the PC-Trple C with gold plating for the PC-triple C Au. This material has a more rational core for sound and better penetrating power than PC-triple C.

Main Differences from PCOCC
-
Differences in crystal structure
PCOCCs have a single-crystal structure and are characterized by smooth signal transmission, but they have a low physical strength aspect.
PC-Triple C is made by continuously connecting multiple crystals by forging to achieve both strength and signal transmission characteristics.
-
Effects of annealing
The annealing process further prepares the crystal structure and improves the signal transmission efficiency in the high-frequency range. This improves the clarity and resolution of the sound.
-
Durability and flexibility
Forged and annealed, PC-Triple C is a highly flexible, well-handled cable and long-lasting material.
-
Successor material for PCOCC
After the production of the PCOCC ended, the PC-Triple C was developed as a successor, aiming to improve sound quality and be both practical.
Due to these features, PC-Triple C is attracting attention as a new standard material for audio cables and accessories.
