- The world’s first and only “Tunable” and "Customizable" phono cartridge -

The Lithium (Li) series cartridge is for those seeking a more intimate presentation of the musicians while the core and timbres of the instruments are better perceived. The high frequencies in the Lithium (Li) are silkier and are not unlike going from a metallic dome tweeter to a silk one in a loudspeaker. The mid-band is more laid back, damped and relaxed. The bass is a rounder. compared to the Aluminum (Al) version. A Lithium (Li) cartridge sounds warmer and pleasing.  The copper content in this alloy provides a well-balanced damping effect that gives this warmer and silkier result.

The new Nitro series is up to now our most advanced cartridges. This complete kit Includes an improved cartridge generator, three (3) pre-selected optimal tonewoods (chosen by us) for you to cover a large musical and sonic spectrum, and it now comes standard with the damping oil treatment, all the necessary voicing, and installation tools in an exotic wooden jewel box.

This cartridge is not limited to and can furthermore be customized to your musical and/or visual preference.
