MoFi MasterTracker Cartridge

MoFi MasterTracker Cartridge


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, MasterTracker accurately extracts music from your LPs and features stellar tracking ability.

I had never ever experienced such vitality and sharp focus from an MM cartridge. More surprisingly, this sharp focus did not come from lean, dry, or overdamped sound. The MasterTracker was simply getting all of the energy information off the record.

MoFi Electronics Master Tracker reminded me again just how great high-output cartridges – 3 mV with the Master Tracker – can sound. With a Micro-Line profile stylus, a V-Twin dual magnet generator, OCC (ohno continuous cast) copper coils, and billet-aluminum body, the MoFi cart on the VPI gave everything a serious dose of oomph. Dynamic drive, organic, and lifelike presence from every LP.
