ULTRATRACKER

 MoFi cartridges are designed by looking at where a record starts: On a cutting lathe like the model used at Mobile Fidelity Sound Lab. UltraTracker 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, UltraTracker features excellent tracking ability.

WELL-DAMPED BILLET ALUMINUM BODY

The well-damped billet aluminum body controls resonances for tight, accurate bass reproduction. UltraTracker delivers finely tuned wide-bandwidth audio, with extension at both frequency extremes and no smearing of detail.

NUDE-ELLIPTICAL DIAMOND STYLUS

By using a nude-elliptical diamond stylus, UltraTracker easily tracks complex dynamic passages. You’ll hear superb detail and experience musical emotionalism that will send shivers down your spine.

STUDIO TONEARM

Custom developed and manufactured in the USA, this 10-inch straight aluminum gimbaled bearing tonearm delivers the ideal balanced of rigidity and low tracking error, so all you hear is what is in the grooves. Tweak to your heart's delight with provisions for adjustable tracking force, VTA, azimuth, and anti-skate.

ISOLATED AC SYNCHRONOUS MOTOR

Our 300 RPM 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.

CONSTRAINED LAYER DAMPENING

StudioDeck features an aluminum plate carefully bonded to an MDF body to add mass and eliminate tonal coloration, maintaining the true sound found on the record.

ANTI-VIBRATION FEET BY HRS

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.

3/4-INCH DELRIN® PLATTER

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.

STEEL AND TEFLON INVERTED BEARING

Our steel inverted bearing system is designed for smooth, quiet rotational stability. The extremely low tolerance combination of steel, bronze, and teflon—found in much more expensive turntables—will provide you many years of high-performance playback.
