The cartridge extends frequency response to 23 kHz while maintaining 4 mV of output for conventional MM phonostages.\u003c\/p\u003e\n\u003cp\u003eThe boron cantilever is the MP-200's principal mechanical distinction from the models below it, reducing flexure and moving mass while retaining the replaceable stylus and high-output operation of the MP design.\u003c\/p\u003e\n\u003ch4\u003eMoving Permalloy Generator\u003c\/h4\u003e\n\u003cp\u003eRather than carrying a permanent magnet at the rear of the cantilever, Nagaoka's MP system uses a lightweight permalloy element within a stationary magnetic system.\u003c\/p\u003e\n\u003cp\u003eThe lower moving mass allows the cantilever to respond more freely to small groove modulations while still producing enough output for a standard 47 kΩ MM phonostage.\u003c\/p\u003e\n\u003ch4\u003eBoron Cantilever\u003c\/h4\u003e\n\u003cp\u003eBoron offers very high stiffness at low mass, helping the cantilever transmit stylus movement accurately without introducing significant flexure. This is especially useful when reproducing small, rapid high-frequency groove movements.\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 a conical stylus, allowing it to follow high-frequency groove modulation more accurately while remaining relatively straightforward to align.\u003c\/p\u003e\n\u003ch4\u003e4 mV Output\u003c\/h4\u003e\n\u003cp\u003eThe MP-200 produces 4 mV at 5 cm\/sec and is designed for standard MM gain.
