Nagaoka JT-80BK. High-End MM Cartridge with Boron Cantilever
The Nagaoka JT-80BK is the flagship model of the Jeweltone series, launched to celebrate Nagaoka’s 80th anniversary. This high-precision Moving Magnet (MM) cartridge combines elegant design with exceptional sonic performance, featuring a nude elliptical diamond stylus mounted on an ultra-rigid boron cantilever.
Pure, Balanced Sound with Zero Listening Fatigue
Built on Moving Magnet principles, the JT-80BK delivers a natural, open, and musical presentation, with firm bass, detailed and seductive mids, and a refined, extended treble. It’s a superb choice for enjoying acoustic recordings, jazz, classical, and vocal music with both fidelity and emotion.

Unlike similarly priced Moving Coil (MC) cartridges, the JT-80BK allows easy stylus replacement, offering long-term value without sacrificing performance.
Compatible with medium-mass tonearms, this cartridge is a versatile solution for discerning vinyl lovers seeking top-tier sound reproduction.
