Our take on the Mobile Fidelity UltraDeck

Mobile Fidelity created this audiophile-grade turntable for fans to play the company's gorgeous remastered records on. Everything but the cartridge is made in the U.S.A. to exacting specifications. We loved it when they demonstrated it at our HQ, and we think you'll feel the same when you drop the needle on your favorite track.

Praise for the Mobile Fidelity UltraDeck from Stereophile magazine:

"The MoFi UltraDeck is one of the most lucid-, engaging-, and natural-sounding record players available for under $5,000. Highly recommended."

The American-made Mobile Fidelity UltraDeck looks great and sounds amazing.

The American-made Mobile Fidelity UltraDeck looks great and sounds amazing.

Thoughtful, innovative design

Mobile Fidelity asked some legendary designers to weigh in on the details of the UltraDeck, because they know details matter to audiophiles. They used a dense, noise-reducing polymer called Delrin® to make the platter, and had a former NASA consultant design the 'table's unique anti-vibration feet. A clever inverted bearing system makes the platter spin flawlessly.

They also worked hard to foolproof the initial setup process by simplifying placement of the counterweight and anti-skating weight. To make things even easier, the Mobile Fidelity UltraPhono phono stage with headphone amplifier and its little brother, the StudioPhono without headphone amplifier, are both perfectly matched to this turntable — straight out of the box.

Product Research


Ultra Tonearm: Custom-developed and manufactured in the USA, the MoFi UltraDeck+'s 10" Ultra tonearm uses smooth, high-quality ball bearings for low friction in the vertical and horizontal plane so all you hear is what is in the grooves. Cardas Audio wiring maintains signal purity from the headshell leads all the way through to the high-quality, gold-plated RCA connectors.

UltraTracker Cartridge (MM): The UltraTracker Cartridge (MM) 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.
  • This turntables come with the tracking force preset by the factory. Using this predetermined factory setting (indicated by the pre-installed yellow tape) prevents the need for a force gauge. Just place the counterweight properly on the back of the tonearm (directly behind the pre-installed yellow tape) and you are done. No need to balance or perform any other steps for tracking weight. Do not remove the yellow tape until the counterweight is installed and you have tested playback.
  • If the yellow tape is removed before installing the counterweight, then the factory setting is lost and a force gauge (like item number 183SFG2) must be used. The cartridge requires the tracking force be set between 1.8g and 2.2g. Using a tracking force gauge (like item number 183SFG2) is necessary because the counter weight has no adjustment markings.

Isolated AC Synchronous Motor: The 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.

1.3" Delrin Platter: The UltraDeck+ turntable features a massive 1.3" 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.

Hardened-Steel Inverted Bearing System: The UltraDeck+'s hardened-steel inverted bearing system is designed for smooth, quiet rotational stability. The extremely low tolerance combination of steel, bronze, and sapphire will provide many years of high-performance playback.

Constrained Layer Dampening: The UltraDeck+ turntable 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: 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 the UltraDeck+ turntable from bad vibrations.

RCA Connections: Connection to the phono input of your amplifier can be made with connecting cables of your choice through the turntable's gold-plated stereo RCA phono jacks and grounding screw. The UltraDeck+ turntable comes supplied with a 49" stereo RCA cable with ground wire.

Note: If your receiver does not have a suitable Phono MM input, a separate phono pre-amplifier (sold separately) is required to connect the turntable to your amplifier.

Dust Cover: The MoFi UltraDeck+ comes supplied with a hinged cover to prevent dust build-up on the turntable.
