High-quality copper, audiophile DIY special, high-grade black shell, oxidation resistance, and small distortion, mainly used for amplifier chassis binding posts and speaker binding posts.
The shell is sand black lacquered copper, and the conductor is a copper rod core. The minimum impedance of the conductor and the recoil torque are compact and reasonable, which can bring out the signal balance without distortion, improving the sound source channel balance and signal transmission.
(Except for the locking screws, the others are all copper. )
