Mobile Fidelity MasterTracker Cartridge


Drawing on 40 years of making records at Mobile Fidelity Sound Lab, the new MoFi Electronics division is focused on improving the sonic integrity of audio reproduction in the home. Our products are the result of multiple collaborations with some of the world’s best audio designers, stemming from decades of experience in the studio.
We designed three new high-output, moving-magnet phono cartridges in collaboration with Allen Perkins of Spiral Groove. MoFi cartridges use a V-Twin dual-magnet generator that mirrors the design of a lathe’s stereo cutter head. Two powerful low-mass magnets are accurately aligned in parallel with the stereo record grooves to achieve excellent channel separation and detail retrieval true to the Original Master Recording



MasterTracker Highlights

Designed in collaboration with Allen Perkins, Mobile Fidelity’s Japan-built phono cartridges follow the same layout as the cutting head responsible for making the grooves on vinyl LPs. MasterTracker boasts superb tracking sense, tremendous accuracy, and coloration-free performance.

MoFi cartridges are designed by looking at where a record starts: On a cutting lathe like the model used at Mobile Fidelity Sound Lab. MasterTracker features a V-Twin dual-magnet generator that mirrors the layout of the cutting head that originally makes a record’s grooves. Employing two low-mass, powerful magnets aligned in a V formation parallel with the record grooves, this cartridge features stellar tracking ability.

MasterTracker features pure Ohno continuous-cast copper coils and a Micro Linear diamond stylus. The result: Surgical precision, pinpoint accuracy, and a purist-based picture of what was cut in the studio.
  • V-Twin dual-magnet generator
  • Micro-Line stylus and tapered cantilever
  • Well-damped billet aluminum body
  • Ohno continuous cast copper coils
  • 3mV output


The well-damped billet aluminum body controls resonances for tight, accurate bass reproduction. MasterTracker has the lightest-weight magnets in the Tracker Series, delivering the kind of detailed, open performance normally attributed to high-end moving-coil cartridges.


By using a Micro-Line diamond stylus shaped like the cutting head of a record lathe. MasterTracker traces vinyl groove walls with microscopic precision.
