Phono Cartridge


Features

• V-Twin dual-magnet generator
• Micro-Line stylus with tapered cantilever
• Well-damped billet aluminum body
• Ohno continuous cast copper coils
• 3mV output

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.

WELL-DAMPED BILLET ALUMINUM BODY

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.

MICRO-LINE DIAMOND STYLUS

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