Ortofon 2M Black LVB 250 Premounted MM Phono Cartridge

The Ortofon 2M Black LVB 250 Premounted is a pre-mounted version of the 2M Black LVB 250, the top-tier flagship of the 2M series, pre-installed on an Ortofon SH-4 headshell. It fully retains the extreme detail, transparency, and sense of speed delivered by the LVB 250's boron cantilever and Nano Tube suspension system, while significantly simplifying the installation process. It is particularly suitable for turntables using S-shaped tonearms (SME bayonet mount), allowing users to easily experience the highest level of Ortofon's current moving magnet cartridges.

Product Information and Design Features

• Boron Cantilever: Boron material is extremely lightweight and highly rigid, significantly enhancing the cantilever's response speed and transparency, allowing the stylus to more accurately track subtle changes in the record groove.
• Nano Tube Suspension System: Utilizes Multi-Wall Carbon Nano Tubes as damping material, effectively improving suspension characteristics and providing better damping control and overall performance.
• Nude Shibata Stylus: Wide contact area, highly restores high-frequency details and complex groove information.
• Split Pole Pins + Silver-plated OFC Coil: Continues the excellent generator system of the high-end 2M series.

These technologies enable the LVB 250 to significantly surpass the standard 2M Black in detail resolution, transient response, and transparency.
