2018 Stereophile Recommended Component:

"MoFi's best moving-magnet cartridge, the MasterTracker is built in Japan using a US-made body machined from aluminum for optimal resonance control. Its twin magnets, reportedly the lightest ones in MoFi's MM line, are aligned in a V formation parallel to the walls of a stereo groove, and its tapered aluminum cantilever is fitted with a Micro-line stylus. Pertinent specs include an output of 3.0mV and a downforce range of 1.8–2.2gm. After using the MasterTracker with MoFi's UltraDeck record player, HR wrote that he had "never ever experienced such vitality and sharp focus from an MM cartridge," and that, "more surprisingly, this sharp focus did not come from lean, dry, or overdamped sound. The MasterTracker was simply getting all of the energy off the record."

Mobile Fidelity ULTRATRACKER

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 ALUMINUM BODY

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.

NUDE-ELLIPTICAL DIAMOND STYLUS

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.
