Thank you for viewing. PS Audio power cable 5.5sq 3-core 1.8m The conductor material is PCOCC. Operation confirmed. PCOCC (single crystal oxygen-free copper), which was once a standard for high-performance conductors for audio, is no longer used in many cables because Furukawa Electric, the manufacturer, stopped producing it. Anyway, in terms of sound quality, my personal impression is that it's powerful and clear. I think it's a serious and unpretentious sound, without extraneous noise. Because the conductor is thick at 5.5sp, it is recommended for places with high power consumption, such as from a wall outlet to a power strip. However, due to this thickness, it may be slightly difficult to handle. Although there is some use, I think it is generally in good condition. Thank you for your consideration.
