Compared with the simpler aluminum cantilever used by the MP-110, the tapered and hardened structure is designed to improve rigidity while keeping moving mass under control.\u003c\/p\u003e\n\u003cp\u003eOutput remains a robust 4.5 mV, allowing the MP-150 to work directly into a conventional MM phonostage. Nagaoka specifies 24 dB of channel separation at 1 kHz and a tracking-force range of 1.5–2 g.\u003c\/p\u003e\n\u003ch4\u003eMoving Permalloy Generator\u003c\/h4\u003e\n\u003cp\u003eNagaoka's MP system replaces the moving magnet of a conventional MM cartridge with a small, lightweight permalloy element attached to the rear of the cantilever. The magnetic system and coils remain stationary in the cartridge body.\u003c\/p\u003e\n\u003cp\u003eReducing moving mass allows the stylus to respond more freely to groove modulation while maintaining the high electrical output associated with an MM-compatible cartridge.\u003c\/p\u003e\n\u003ch4\u003eHardened Tapered Aluminum-Alloy Cantilever\u003c\/h4\u003e\n\u003cp\u003eThe MP-150 uses a hardened tapered aluminum-alloy cantilever rather than a simple straight aluminum tube. Tapering removes material where it is less structurally necessary, while the hardened structure improves rigidity.\u003c\/p\u003e\n\u003ch4\u003eElliptical Diamond\u003c\/h4\u003e\n\u003cp\u003eThe 0.4 × 0.7 mil elliptical diamond has a narrower tracing radius than the conical stylus fitted to the MP-100, allowing it to follow shorter-wavelength groove modulation more accurately.\u003c\/p\u003e\n\u003ch4\u003e4.5 mV Output\u003c\/h4\u003e\n\u003cp\u003eWith 4.5 mV of output, the MP-150 is designed around standard MM gain and a 47 kΩ load.
