By using 23 high-purity oxygen-free copper per core, transmission loss is suppressed and the cable’s original capabilities are demonstrated. In addition, the 8-core configuration dramatically improves the sense of localization and the amount of information. In addition, by applying silver plating, it clearly expresses the outline of the sound and the brightness of the high range while maintaining the sound pressure of the low range. We realize sound with delicate and powerful sharpness.
