Product Description: YIQ-A uses a solid silver-plated center conductor insulated with Hard Cell Foam (HCF). Silver-plating greatly improves high frequency performance for a fraction of the cost of solid silver. Nitrogen injected HCF reduces distortion caused by the insulating material, and helps maintain a stable 75O. The combination foil and braid shield provides 100% protection coverage. Gold-plated RCA connectors are professionally attached with superior AudioQuest solder.
