This is the Genuine Nagaoka JN-P150 needle for the Nagaoka MP series cartridge. The JN-P150 features Nagaoka's polished SUPER-fine elliptical diamond tip. This upgraded elliptical tip enriches tone and detail by tracking the grooves even better than its elliptical predecessor, the JN-P110. Also included is Nagaoka's updated hardened, low mass tapered cantilever for optimal sound reproduction. This is the original replacement stylus for the Nagaoka MP-150 cartridge.
