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.
