Nagaoka JT-80BK Jewel Tone MM Cartridge

Nagaoka JT-80BK Jewel Tone MM Cartridge

The JT-80BK is the premium model in Nagaoka's Jewel Tone moving-magnet range, using a nude elliptical diamond on a boron cantilever and a revised body structure designed to control unwanted resonance.

This is a cartridge upgrade where setup matters. Correct overhang, alignment, tracking force and phono-stage loading are all part of getting the result the cartridge is capable of delivering.

Cartridge Design

The slanted front shape also makes the stylus easier to see during cueing and alignment, while the replaceable JTS-80BK stylus keeps long-term ownership practical.

System Matching and Setup

Use the manufacturer's recommended tracking-force range and a standard 47kΩ phono input where specified. Tonearm effective mass, headshell weight and available counterweight range should also be checked before installation.
