The 2M Black LVB 250 upgrades the great build of the 2M Black with a boron cantilever and our very own Nano Tube suspension system. The result is a sound so precise and so detailed that you feel like you have let the artist into your house and have them playing right in your living room.

The 2M Black is mounted on our classic SH-4 headshell.

Accuracy level

The 2M Black is an amazing cartridge and, by many, considered the ultimate in moving magnet. So, why would we attempt to create something even better? Because perfection runs in our blood.

Stylus

The 2M Black LVB 250 upgrades the great build of the 2M Black with a Nude Shibata diamond on a boron cantilever. The use of an extremely stiff and lightweight Boron cantilever adds remarkable transparency, speed, and responsiveness.

The Nude Shibata stylus’ slim, highly polished profile allows an exceedingly wide contact area to the groove walls and ensures notably detailed reproduction throughout the spectrum, including even the highest frequencies.

Features

To attain an optimal interaction between compliance and damping, a new rubber compound for the suspension system has been developed. The new rubber compound formula is based on the Multi Wall Carbon Nano Tubes' (MWCNT) highly efficient nano filler. The new MWCNT-based compound offers desirable mechanical properties, which ensure better damping and improve the overall performance of the cartridge.
