Rather than moving a relatively heavy permanent magnet, the cantilever carries a small piece of lightweight permalloy that is magnetized by the stationary magnetic system inside the cartridge body.\u003c\/p\u003e\n\u003cp\u003eReducing the mass attached to the cantilever gives the stylus greater freedom to follow groove modulation while retaining the high electrical output associated with an MM-compatible cartridge.\u003c\/p\u003e\n\u003ch4\u003e0.6 Mil Conical Diamond\u003c\/h4\u003e\n\u003cp\u003eThe MP-100 uses a 0.6 mil bonded conical diamond. Because a conical tip is rotationally symmetrical, its relationship to the groove is less sensitive to small alignment errors than more complex stylus profiles, making setup relatively straightforward.\u003c\/p\u003e\n\u003cp\u003eThe profile also makes the MP-100 well suited to general record playback, including collections that contain older or less-than-perfect pressings.
