RCA cable, 1.0 m pair, uses high-purity silver wire with VariStrand structure. KIMBER KABLE's unique “3-core blade structure” is recommended for those who want to improve sound loss anyway. The strengths and weaknesses are clear, and the presence of each instrument, especially the strings of piano, stringed instruments, etc., stretches very nicely. The spread of the mid to low range is also excellent. There is a sense of dynamism that is hard to imagine from the delicate design. There are abrasions on the tubes and plug shells (Kojima Yosuke)
