About the UltraTracker MM
The Mobile Fidelity Sound Labs UltraTracker MM Phono Cartridge is a high-performance moving magnet cartridge designed to extract immense detail, dynamics, tone, and texture from vinyl LPs. It features a unique V-twin dual-magnet generator that mirrors the layout of the original cutting head used to create record grooves, providing excellent tracking ability and stunning channel separation. Hand-built in Japan with a cartridge housing milled from solid aluminum billet in the USA, it is fine-tuned by Mobile Fidelity engineers and Spiral Groove founder Allen Perkins. The well-damped billet aluminum body controls resonance for tight, accurate bass and wide frequency response from 20Hz to 25kHz without smearing or coloration. The nude elliptical diamond stylus tracks complex dynamic passages with precision, delivering accurate and fearless reproduction of complex music passages. It is designed with a tracking force range of 1.8 to 2.2 grams, weighs 9.7 grams, and outputs 3.5mV. The cartridge has an impedance of 47kOhm and capacitance of 100pF, with static compliance of 35 x 10^-6/dyne and dynamic compliance of 10 x 10^-6/dyne. This cartridge embodies Mobile Fidelity's philosophy of bringing master-tape quality to vinyl playback, offering audiophiles a premium listening experience.
