Mofi UtraTracker MM Cartridge



UltraTracker MM
MoFi cartridges are designed by looking at where a record starts: On a cutting lathe like the model used at Mobile Fidelity Sound Lab. UltraTracker 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, UltraTracker features excellent tracking ability.

Well-Damped Billet Aluminium Body   Nude-Elliptical Diamond Stylus

The well-damped billet aluminum body controls resonances for tight, accurate bass reproduction. UltraTracker delivers finely tuned wide-bandwidth audio, with extension at both frequency extremes and no smearing of detail.


By using a nude-elliptical diamond stylus, UltraTracker easily tracks complex dynamic passages. You’ll hear superb detail and experience musical emotionalism that will send shivers down your spine.
