Ortofon 2M Black LVB 250 Cartridge
The 2M Black LVB 250 builds on the concept of the original 2M Black cartridge design to take one step further toward true high-end sound. Redefining what is possible from a moving magnet (MM) cartridge, the 2M Black LVB 250 is truly an exercise in technical excellence.
The 2M Black LVB 250 uses a Nude Shibata diamond on a Boron cantilever. This combination is also found on the acclaimed MC Cadenza Black cartridge. The Nude Shibata stylus’s slim, highly polished profile allows for an exceedingly wide contact area with the record groove walls and ensures notably detailed reproduction throughout the spectrum, including even the highest frequencies. The use of an extremely stiff and lightweight Boron cantilever adds remarkable transparency, speed, and responsiveness to the sound.
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. Also, the new MWCNT rubber compound allows for more environmental-friendly production, adding further benefit. The MWCNT powder is applied in a rubber polymer matrix and not in a powdered form, which makes the production process more clean, non-polluting and energy saving.
With an optimal weight of 7.2 g and compliance suited to most modern tonearms, the 2M Black LVB 250 is easily compatible with an endless array of modern High-End equipment and is the ultimate solution for high fidelity reproduction.
In all other elements of its general design, the 2M Black LVB 250 draws from the coveted 2M range’s principles. Its structure, materials and generator system are all drawn from the standard 2M Black for a proven high-fidelity performance. For that reason, the 2M Black LVB 250 stylus can also fit on and bring a notable upgrade to existing 2M Bronze and 2M Black customers.
