MoFi Mastertracker

MoFi MasterTracker – Audiophile MM Cartridge

The MoFi (Mobile Fidelity) MasterTracker is—from a technical and sonic perspective—where analog precision meets expert design. It’s built to extract music from vinyl with accuracy that echoes the original cutting process.

Exceptional Design & Sound Fidelity

V‑Twin Dual‑Magnet Generator
Two low-mass magnets aligned in a “V” formation parallel to the groove mimic the cutting lathe head. This design delivers stellar channel separation, tracking precision, and overall musical clarity.

Micro‑Line Diamond Stylus
Shaped like a record cutting head, this stylus traces groove walls with microscopic accuracy, reducing groove distortion and enhancing surface noise rejection.

Billet Aluminum Body with Superior Damping
The durable, well-damped chassis minimizes resonance and vibration, delivering tight, articulate bass and overall clean performance.
