MoFi Electronics UltraDeck + Turntable w/ UltraTracker Cartridge
The MoFi Electronics UltraDeck + Turntable package includes the UltraTracker MM phono cartridge.
The word “Ultra” is synonymous with Mobile Fidelity Sound Lab's philosophy. It represents our extreme pursuit of the highest level of reproduction of recorded sound—beyond the status quo—to provide music lovers with the experience of hearing the Original Master Recording in their home. Whether you're enjoying a standard LP or one of our UltraDisc One-Step limited-edition records, UltraDeck will deliver faithful playback of what's in the grooves. Advanced technology, user-friendly features, and unflappable design elements ensure phenomenal playback—ultimately bringing the sound of Mobile Fidelity’s famous studio into your home.
Mofi's stepped-pulley AC motor provides excellent speed stability for pitch accuracy and rhythmic drive. The Delrin® pulley has two positions for 33 1/3 and 45 RPM speed selection. Motor vibrations are kept away from the platter and stylus by using advanced dampening materials that decouple the motor from the rest of the turntable.
The Mofi UltraDeck features three aluminum plates carefully bonded to an MDF body to add mass and eliminate tonal coloration, maintaining the true sound found on the record.
Any vibration of the stylus that is not created by the grooves in the record is a distortion that will mask musical detail. Developed in conjunction with the engineering team at Harmonic Resolution Systems, the world leader in vibration isolation for audio equipment, the included MoFi anti-vibration feet isolate your turntable from bad vibrations.
The Mofi Electronics UltraDeck features a massive 1.3-inch Delrin® platter. The increased mass creates blacker sonic backgrounds and a lower noise floor. Delrin® is a next-generation polymer developed by Dupont. In the world of audio, Delrin's® highly crystalline structure presents a wonderful impedance match to vinyl records, effectively grounding unwanted noise and keeping it away from the stylus.
Mofi's hardened-steel inverted bearing system is designed for smooth, quiet rotational stability. The extremely low tolerance combination of steel, bronze, and sapphire—found in much more expensive turntables—will provide you with many years of high-performance playback.
The MoFi Electronics UltraTracker MM Phono Cartridge is included with the UltraDeck + Package. It 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.
