Ortofon 2M Black LVB 250 Cartridge

Why choose the Ortofon 2M Black LVB 250 cartridge

The Ortofon 2M Black LVB 250 is the top model in the 2M Series, built from the standard 2M Black generator system but fitted with a boron cantilever and Ortofon's Nano Tube suspension. It's aimed at owners who already know the 2M Black's quad-coil motor system and want a further step in tracing speed and damping control, rather than buyers looking for a first moving magnet cartridge. The 2M Black LVB 250 was released in December 2020 to mark the 250th anniversary of Ludwig van Beethoven's birth, and it sits above the rest of the 2M range as the cartridge Ortofon builds when the standard 2M Black's electrical design is paired with its highest-grade mechanical parts.

What makes the 2M Black LVB 250 different from the standard 2M Black?

The 2M Black LVB 250 takes the 2M Black's quad-coil generator and changes two mechanical components: the cantilever and the suspension. Where the 2M Black uses its standard cantilever and rubber damper, the LVB 250 fits a boron cantilever and a Nano Tube suspension system built around a different rubber compound. Because the electrical generator stays the same, the upgrade is about how accurately the stylus tip's movement is transmitted and damped before it reaches the coils, rather than a change in output level or impedance.

How does the boron cantilever affect cartridge performance?

A boron cantilever carries the nude Shibata diamond in place of the aluminium cantilever used elsewhere in the 2M range. Boron is stiffer and lighter than aluminium for the same dimensions, so the cantilever flexes less under the forces generated as the stylus traces a groove. Less flex means the cantilever transmits stylus movement to the coil assembly with less delay and less self-resonance, which is what gives the LVB 250 its faster, more responsive tracing of high-frequency groove modulation compared with a standard aluminium-cantilever design.

How does the Nano Tube suspension system improve damping?

The 2M Black LVB 250's suspension uses a rubber compound formulated with Multi Wall Carbon Nano Tubes, or MWCNT, as a filler material. This nano-filler changes the mechanical properties of the rubber, giving it more consistent damping characteristics than a standard compound. Suspension damping controls how the cantilever's motion settles after each groove transient, so a more efficient damping material keeps the stylus assembly stable and reduces unwanted resonance as it tracks complex or high-amplitude groove sections.

How does the stylus profile affect detail retrieval?

The cartridge uses a nude Shibata diamond with a tip radius of 6/50µm, mounted directly to the boron cantilever rather than bonded to a separate shank. The Shibata profile's slim, highly polished edges create a wide contact area against the groove walls, which lets the stylus follow fine modulation across the audible spectrum, including the highest recorded frequencies. Mounting the diamond as a nude stylus removes the added mass of a bonding shank, keeping the moving assembly light enough for the boron cantilever's stiffness to be fully useful.

Which 2M Series configuration suits your turntable and tonearm?

Ortofon builds the 2M Series in four mounting configurations to match different turntable and tonearm designs: the standard 2M for the most common conventional turntables, the 2M Premounted for direct fitting to S-shaped tonearms without separate cartridge mounting, the 2M Verso for bottom-mount headshells, and the 2MR for low-profile turntables and tonearms such as those made by Rega. The 2M Black LVB 250's generator and stylus assembly are shared across these body options, so the choice between them comes down to which mounting format matches your tonearm rather than a difference in cartridge performance. A premounted 2M Black LVB 250 weighs 16.7g complete, compared with 7.2g for the cartridge alone, which is worth checking against your tonearm's counterweight range before ordering that configuration.

What tracking force and geometry does it need for correct setup?

The 2M Black LVB 250 has a recommended tracking force of 1.6g, within a permitted range of 1.5g to 1.7g, and is designed for a tracking angle of 20 degrees. Dynamic lateral compliance is rated at 22µm/mN, which needs to suit the effective mass of the tonearm it's fitted to if the combination is to track accurately at the recommended force. Tracking ability is rated at 80µm at 315Hz, indicating the level of groove modulation the stylus can follow without mistracking, which is relevant when setting force toward either end of the recommended range during setup.

How should you match electrical output and loading to your phono stage?

The cartridge outputs 5mV at 1kHz, measured at a stylus velocity of 5cm/sec, which falls within the input range of a standard moving magnet phono stage, so it doesn't need a step-up transformer or a moving coil input. Internal impedance is 1.2kOhm with an internal inductance of 630mH, and Ortofon recommends a load resistance of 47kOhm together with a load capacitance of 150 to 300pF. Capacitance loading interacts with the cartridge's inductance to shape its high-frequency response, so checking your phono stage and cable capacitance against this range, and adjusting where your equipment allows, keeps the frequency response close to the cartridge's rated 20Hz to 20kHz, +2/-1dB specification.
