This model uses 4 types of wire, mainly untreated high-purity 6N copper at the 2.5 m end of the speaker cable. Of course, with the starcard system, where 2 of the 4 cores are twisted and connected to each other, it is also possible to use each of the 4 cores as bi-wiring by dividing them into high and low frequencies (Murakoshi Yoichi)
