General:
2018 Stereophile Recommended Component

High-output moving magnet series with twin low-mass magnets mirroring a lacquer cutter-head for accurate reproduction.

- V-Twin dual-magnet generator
- MicroLine stylus
- Dark grey billet 6061 body
- Ohno copper coils
- 3 mV
- Weight 9.7 g
- Tracking 1.8 - 2.2 g

This was removed from a new MoFi turntable so it will come in aftermarket packaging.

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.

Testing Process:

We start by doing a detailed physical inspection under light magnification to asses the cantilever condition, its position in the cartridge body and the condition of the suspension. We also inspect any coil wires and the output connections to make sure it hasn’t been strained. We then perform a light cleaning with specialized agents and blow it dry with compressed air.

We then perform a more detailed inspection with our Wild Heerbrugg professional microscope. From there we can asses the wear and quality of the stylus and determine how much use it has had and if there are any mechanical issues. We can also identify if it needs further cleaning or care.

We then move the cartridge to a digital microscope where we take photo os the cantilever for future reference.

We then move to the test bench where we can check for continuity of each channel and resistance.

On certain cartridges and it the technician feels necessary we install the unit on a turntable and run a few test records to ascertain tacking ability, distortion and compliance.
