Nagaoka JT-80BK

The Nagaoka JT-80BK phono cartridge is a high-end moving magnet cartridge designed to deliver exceptional analogue playback performance. In addition, it was developed to celebrate Nagaoka’s 80th anniversary, combining advanced engineering with refined musicality for demanding vinyl listeners.

With its exclusive Moving Permalloy technology and boron cantilever, the JT-80BK delivers precise tracking and highly detailed sound reproduction. As a result, it achieves performance levels comparable to premium moving coil cartridges while retaining the practical advantages of a moving magnet design.

Advanced Japanese cartridge engineering

The JT-80BK features Nagaoka’s proprietary Moving Permalloy technology, which improves signal accuracy and overall cartridge performance. Therefore, it provides excellent musical precision while maintaining the reliability and ease of use associated with MM cartridges. In addition, the cartridge is manufactured in Japan with strict quality control for consistent performance.

Boron cantilever and nude elliptical stylus

The lightweight boron cantilever helps transfer groove vibrations with exceptional accuracy. As a result, unwanted resonance is reduced while tracking precision is improved. Furthermore, the nude elliptical diamond stylus, shaped to 0.4 × 0.7 mm, follows groove details with high accuracy, which helps reveal subtle musical textures and fine detail.

Natural and balanced sound character

The JT-80BK delivers a balanced and natural sound signature. In addition, bass remains firm and controlled, while the midrange offers strong presence and musical richness. At the same time, high frequencies sound refined and detailed without becoming harsh, which makes long listening sessions more enjoyable.

Wide frequency response and stereo precision

With a frequency response of 20 Hz to 20 kHz, the cartridge reproduces the full audible range with impressive balance. Furthermore, channel separation of 25 dB at 1 kHz helps create a stable stereo image and precise instrument placement. As a result, recordings feel spacious and well organised.

Flexible compatibility and installation

The JT-80BK is designed for medium-mass tonearms and features a standard 1/2-inch mount for broad compatibility. In addition, its 47 kΩ impedance ensures seamless pairing with most MM phono preamps. The recommended tracking force between 1.3 and 1.8 grams also allows careful adjustment for different setups.
