Nagaoka JN-P700
Overview
The JN-P700 replacement stylus, specially designed for Nagaoka’s flagship MP-700 cartridge, embodies the craftsmanship of a manufacturer renowned worldwide for the exceptional musical quality of its products. Launched in May 2025 to accompany the new MP-700 cartridge, the JN-P700 allows audiophiles to maintain the optimal performance of their high-end vinyl setup.
Moving Permalloy Technology and Exceptional Materials
The JN-P700 utilizes Nagaoka’s distinctive Moving Permalloy technology, which employs a lightweight permalloy oscillator attached to the cantilever. This design significantly reduces the moving mass compared to conventional moving magnet cartridges, allowing the stylus to track groove modulations with greater freedom and precision.
The boron cantilever is a major technical feature of the JN-P700. This material, lighter and stiffer than traditional aluminum, faithfully transmits vibrations from the tip to the transducer system. Its exceptional resistance to deformation preserves optimal geometry even during complex musical passages.
The nude microridge diamond, cut to precise dimensions of 0.12 x 0.3 mil, maximizes the contact area with the groove walls. This sophisticated geometry extracts more information from microgrooves while reducing wear on the vinyl record. Japanese artisanal polishing ensures a perfectly smooth surface for optimal gliding in the grooves.
Technical Design and Advanced Suspension System
Nagaoka has equipped the JN-P700 with the “softest damper” in its range, allowing the boron cantilever and microridge diamond to fully express their potential. This ultra-flexible suspension permits large amplitude movements without compromising playback stability.
To balance this flexibility, an innovative suspension system with an integrated wire precisely controls the movements of the cantilever and stylus. This technical solution ensures the necessary stability while preserving clarity, especially in the high frequencies. The result is a stereo separation of 30 dB at 1 kHz and channel balance within 1 dB.
Exclusive Compatibility with the MP-700 Cartridge
The JN-P700 is specifically developed for the Nagaoka MP-700 cartridge, the flagship model launched to celebrate the brand’s 85th anniversary. This exclusive compatibility ensures perfect integration with the ultra-duralumin cartridge body treated with a triple-layer process (nickel plating, black tinning, insulating coating).
The geometry of the JN-P700 fits perfectly with the Samarium-Cobalt magnetic system of the MP-700. This technical synergy preserves optimal electrical characteristics: 4 mV output voltage, frequency response from 20 to 27,000 Hz, and a recommended load impedance of 47 kΩ.
Sound Performance and Musical Reproduction
The JN-P700 delivers remarkably precise sound reproduction, inheriting the acoustic qualities that have built Nagaoka’s reputation. The combination of boron cantilever and microridge diamond reveals the subtlest details of recordings while preserving the natural musicality of vinyl.
According to Nagaoka, Moving Permalloy technology offers “the best of both worlds”: the finesse of moving coil cartridges and the convenience of moving magnet cartridges with their replaceable stylus. This hybrid approach eliminates the usual compromises between performance and ease of maintenance.
The extended frequency response up to 27 kHz captures the highest harmonics, contributing to the sense of air and transparency characteristic of the finest analog systems. The optimized tracking force of 1.4 grams ensures a perfect balance between information retrieval and record preservation.

Frequently Asked Questions
Is the JN-P700 compatible with other Nagaoka cartridges?
No, the JN-P700 is exclusively designed for the MP-700 cartridge. Each Nagaoka stylus has a specific geometry tailored to its corresponding cartridge. Using an incompatible stylus would compromise performance and could damage the equipment.
How can I identify stylus wear?
Signs of wear include reduced clarity in the highs, decreased stereo separation, or distortion at the end of a side. Microscopic examination reveals the gradual rounding of the initially angular microridge diamond tip.
Does the JN-P700 perform differently from the original stylus?
The replacement JN-P700 has identical characteristics to the original MP-700 stylus. Nagaoka maintains the same manufacturing tolerances and materials to ensure consistent performance throughout the cartridge’s lifespan.
