Available at \u003cstrong\u003eVinyl Sound Buffalo, NY\u003c\/strong\u003e, the MP-300 delivers sophistication, refinement, and exceptional detail retrieval at every audible frequency — offering the musicality and precision that only Nagaoka's 80+ years of in-house stylus and cartridge manufacturing can produce. Nimble in the groove and effortless on the ears, the Nagaoka MP-300 is the kind of cartridge you keep reaching for.\u003c\/p\u003e\n\n\u003cp\u003eWhat sets the MP-300 apart from the MP-110 and MP-200 is its \u003cstrong\u003ehardened boron cantilever\u003c\/strong\u003e — the same ultra-lightweight, high-rigidity material used in the flagship MP-500 — combined with a \u003cstrong\u003enaked elliptical diamond stylus\u003c\/strong\u003e with a superfine polish. Boron is stiffer than aluminium at a fraction of the mass, allowing the stylus to track groove modulations with greater speed and accuracy, reproducing transients, inner detail, and subtle dynamic nuance that softer cantilever materials simply cannot resolve. The result is a cartridge that is destined to become a classic from the moment it drops into the groove.\u003c\/p\u003e\n\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eExclusive super-rigid cartridge body for ultra-low resonance and superb fidelity\u003c\/li\u003e\n  \u003cli\u003eHardened low-mass, high-strength boron cantilever for fast, accurate groove tracking\u003c\/li\u003e\n  \u003cli\u003eSuperfine polished special elliptical bonded diamond stylus (0.4 x 0.7 mil)\u003c\/li\u003e\n  \u003cli\u003ePowerful samarium cobalt magnet for high output and dynamic energy\u003c\/li\u003e\n  \u003cli\u003eCarbon fibre reinforced plastic shoe for vibration damping and stability\u003c\/li\u003e\n  \u003cli\u003eAnti-ferromagnetic permalloy shield casing for low noise and EMI rejection\u003c\/li\u003e\n  \u003cli\u003eMoving Permalloy (MP) generator for natural, musical, wide-bandwidth signal\u003c\/li\u003e\n  \u003cli\u003eReplaceable stylus — compatible with Nagaoka JN-P300 replacement stylus\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCartridge type\u003c\/td\u003e\n\u003ctd\u003eMoving Magnet (MM) — Moving Permalloy (MP)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput voltage\u003c\/td\u003e\n\u003ctd\u003e3.0mV (at 5cm\/sec)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFrequency response\u003c\/td\u003e\n\u003ctd\u003e20–25,000Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eChannel separation\u003c\/td\u003e\n\u003ctd\u003e25dB (at 1kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eChannel balance\u003c\/td\u003e\n\u003ctd\u003e1.0dB or less\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLoad resistance\u003c\/td\u003e\n\u003ctd\u003e47kΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCantilever\u003c\/td\u003e\n\u003ctd\u003eHardened boron (low-mass, high-strength)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStylus tip shape\u003c\/td\u003e\n\u003ctd\u003eElliptical — 0.4 x 0.7 mil\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStylus tip material\u003c\/td\u003e\n\u003ctd\u003eNaked diamond\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTracking force range\u003c\/td\u003e\n\u003ctd\u003e1.3–1.8g\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCartridge weight\u003c\/td\u003e\n\u003ctd\u003e8.0g\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eReplacement stylus\u003c\/td\u003e\n\u003ctd\u003eNagaoka JN-P300\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003csmall\u003eStylus replacement interval: approximately 150–200 hours under normal home listening conditions.

It features a hardened boron cantilever, a superfine polished naked elliptical diamond stylus, and a powerful samarium cobalt magnet, delivering high-definition sound across the full 20–25,000Hz frequency range. It is compatible with any turntable that accepts a standard MM cartridge.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between the Nagaoka MP-300 and MP-200?\u003c\/h3\u003e\n\u003cp\u003eThe key difference is the cantilever material. The Nagaoka MP-200 uses a high-strength aluminium alloy cantilever, while the MP-300 upgrades to a hardened boron cantilever — a stiffer, lighter material that tracks groove modulations more accurately and resolves finer detail. The MP-300 also features a naked diamond stylus with a more refined polish, resulting in improved transient response, inner detail, and dynamic contrast compared to the MP-200.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between the Nagaoka MP-300 and MP-500?\u003c\/h3\u003e\n\u003cp\u003eBoth the MP-300 and MP-500 use a boron cantilever, but the flagship MP-500 upgrades to a line-contact diamond stylus — a more refined tip geometry that contacts a larger portion of the groove wall, retrieving even more musical information and reducing record wear. The MP-300 uses an elliptical stylus, which is an excellent performer at its price point, while the MP-500 represents the ultimate expression of the MP Series.\u003c\/p\u003e\n\n\u003ch3\u003eIs the Nagaoka MP-300 compatible with my turntable?\u003c\/h3\u003e\n\u003cp\u003eYes — the Nagaoka MP-300 is a standard moving magnet (MM) cartridge compatible with virtually all turntables that accept a standard half-inch mount headshell. It requires a phono stage with a 47kΩ MM input, which is standard on integrated amplifiers, receivers, and dedicated phono preamplifiers. Recommended tracking force is 1.3–1.8g, making it suitable for most standard tonearms.\u003c\/p\u003e\n\n\u003ch3\u003eWhat replacement stylus does the Nagaoka MP-300 use?\u003c\/h3\u003e\n\u003cp\u003eThe Nagaoka MP-300 uses the Nagaoka JN-P300 replacement stylus, which can be swapped without tools by simply sliding the old stylus off and the new one on. Nagaoka recommends replacing the stylus every 150–200 hours of use under normal home listening conditions to maintain sound quality and protect your record grooves.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the Nagaoka MP-300 need a phono preamplifier?\u003c\/h3\u003e\n\u003cp\u003eYes. The Nagaoka MP-300 is a moving magnet (MM) phono cartridge with an output voltage of 3.0mV. It requires a phono preamplifier with a standard MM input (47kΩ load resistance) to amplify and apply RIAA equalisation to the signal before it reaches your amplifier. Many integrated amplifiers and receivers include a built-in MM phono stage. If yours does not, a separate phono preamplifier is required.\u003c\/p\u003e\n\n\u003ch3\u003eWhere can I buy the Nagaoka MP-300 in Buffalo, NY?\u003c\/h3\u003e\n\u003cp\u003eThe Nagaoka MP-300 MM Phono Cartridge is available at \u003cstrong\u003eVinyl Sound\u003c\/strong\u003e, Buffalo's dedicated hi-fi and vinyl specialist.
