MoFi Electronics UltraTracker MM Phono Cartridge
The MoFi Electronics UltraTracker MM Phono Cartridge is hand-built in Japan and designed to extract more information from the grooves of LP's. The logic seems obvious to Mobile Fidelity: The form of high-output MM phono cartridge, like the high-end UltraTracker, should follow the same layout as the cutting head responsible for making the precious grooves you see on vinyl LPs. UltraTracker touts a "V-twin" dual-magnet generator comprised of two powerful magnets aligned in a formation parallel with the stereo record grooves. Developed in collaboration between Mobile Fidelity engineers and Spiral Groove founder Allen Perkins, UltraTracker extracts immense amounts of detail, dynamics, tone, and texture from LPs. Its physical configuration means it is literally made to live in records' grooves, giving it innate advantages and stunning channel separation few other cartridges claim at this price.
Hand-built in Japan with its cartridge housing milled from solid aluminum billet in the USA, and fine-tuned by Mobile Fidelity and Mr. Perkins, UltraTracker is true to its name – a cartridge that boasts insanely good tracking sense. Its nude elliptical stylus and well-damped billet aluminum body yield practical payoffs you'll immediately hear. Accurate, fearless reproduction of supremely complex passages. Taut, lifelike, edge-free bass. End-to-end frequency response. No smearing, no coloration. Such prized playback characteristics are owed to the countless hours Mr. Perkins invested removing unwanted resonance and employing next-generation dampening materials to improve the sound. Conceived with the same philosophy that has yielded more than 40 years' worth of Mobile Fidelity's world-famous Original Master Recordings, UltraTracker brings master-tape pedigree to your own system.
