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.
