Why is oxygen-free copper (OFC) used in the conductors of this parallel audio cable?

Oxygen‑free copper conductors, specified in accordance with IEC 60228 for conductor construction, contain minimal oxygen and other impurities that could otherwise form oxides at grain boundaries. This high‑purity material ensures maximum electrical conductivity and reduces signal loss due to resistance. In professional audio applications, even subtle losses can degrade transient response and high‑frequency clarity. By using OFC, Chinne Electric’s parallel audio cable maintains the integrity of the original audio signal from amplifier to speaker, preserving the nuance and dynamics that touring rigs and fixed installations demand.
