Ortofon 2M Black LVB 250 Moving Magnet Phono Cartridge
This year, to commemorate the 250th anniversary of the birth of Ludwig van Beethoven, Ortofon announced the release of the 2M Black LVB 250 Exclusive Model.
The 2M Black LVB 250 has been recreated from the concepts of its predecessor, the 2M Black, but the 2M Black LVB 250 performance takes one step further to enhance the cartridge’s capabilities and technical excellence.
The 2M Black LVB 250 uses a Nude Shibata diamond on a Boron cantilever, the combination known from the acclaimed MC Cadenza Black cartridge.
The Nude Shibata stylus’s 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.
The use of an extremely stiff and lightweight Boron cantilever adds remarkable transparency, speed and responsiveness.
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.
