Ortofon 2M Black LVB 250 Moving Magnet Phono Cartridge

Ortofon’s new 2M Black LVB 250 cartridge is at the top table of moving magnet cartridges 

"...the 2M Black LVB 250 is a big improvement, opening up the soundstage, throwing light onto the back of the recorded acoustic. It adds subtlety, detail, nuance, texture and speed too...

...The 2M Black LVB 250 was again a revelation, conjuring up a really wide soundstage inside which the instrumentalists were better etched. Depth perspective was excellent, and the finesse with which this cartridge did its stuff was startling from a moving magnet perspective...

...It (the 2M Black LVB 250 – red.) certainly has a worthy claim to being the best sounding moving magnet around."

Benefits of high-end materials

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.

The new rubber compound formula

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.
