Nagaoka JT-80 BK

The black JT-80 has a boron cantilever, which produces a sound with fast transients. It features a bare diamond with an elliptical cut.

The JT-80 BK has a well-balanced sound across the entire range from low to high frequencies. It handles jazz and classical music superbly.

Built-in nut
The JT-80 has a built-in nut for attachment to the tonearm. This is a major advantage as it reduces the risk of resonance. Another advantage is that you don't need a loose nut to be in place during assembly.

However, the built-in nut means that the JT-80 can only be mounted on tonearms or shells that have through holes so that the screw can be attached from above.
