Ortofon 2M Black LVB 250 MM-Cartridge

Ortofon 2M Black LVB 250 MM-Cartridge



Review: "The latest variation on Ortofon’s long-running 2M moving-magnet cartridge design pays tribute to Beethoven 250 years after his birth, complete with a picture of the composer on the side of its body. It fits the bill with a silky, sophisticated presentation especially well-suited to classical, jazz and acoustic music. Refined and composed, it uses a version of the stylus and cantilever found in the company’s Cadenza Black moving-coil cartridge. This, along with a new suspension, all contributes to a sound that boasts rock-solid imaging, great stereo focus and depth along with a smooth, lush view of strings and other acoustic instruments."

Discription

This year, to commemorate the 250th anniversary of the birth of Ludwig van Beethoven, we announce the release of the 2M Black LVB 250 Exclusive Model. 

The 2M Black flagship from Ortofon is widely acknowledged as being one of the best MM cartridges on the market, but at Ortofon being the best doesn’t mean that we can’t get better.
 
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.
