Recommended Component 2025 - Stereophile
Editors' Choice Award 2024 – The Absolute Sound Magazine
An Extreme Pursuit of the Purest Vinyl Sound Reproduction
The word "ultra" is synonymous with Mobile Fidelity Sound Lab's philosophy. It represents the company’s extreme pursuit of the highest level of reproduction of vinyl-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 a Mobile Fidelity UltraDisc One-Step limited-edition record, UltraDeck will deliver faithful playback of what's in the grooves.
Award-Winning Performance
The Absolute Sound magazine honored the UltraDeck with an Editors' Choice Award for 2024.
"When Mobile Fidelity decided to create a line of hardware it wisely brought in Allen Perkins of Spiral Groove to design the turntables, and those tables deliver a lot of bang for the buck."
"The belt-driven ’table features an isolated AC synchronous motor, a hefty Delrin platter, and a constrained-layer-damped chassis with feet designed by Mike Latvis of HRS. Smoothness, imaging, musicality, pitch stability, and presence emerged as strong themes. The UltraDeck is a smartly conceived and finely honed design that’s already earning its place as an instant classic."
"Recommended Component" Honors
Stereophile honored the MoFi UltraDeck by awarding it the magazine's coveted Recommend Component status for 2025.
Says Stereophile, "According to HR, the UltraDeck, when used with MoFi's top-of-the-line moving magnet cartridge, the MasterTracker (a $2198 package; the MasterTracker is sold separately for $699), didn't provide the 'deep 'black' backgrounds or enormous sound spaces 'of the considerably more expensive AMG Giro G9 player, "'but it did present me with an infectious, easy-flowing, liquid vitality.' According to Herb, the MoFi combo 'had stronger energy, achieved bigger dynamic swings, and was more detailed than comparatively priced 'tables'" from other manufacturers.
"Ease and Effortlessness"
"I had an absolutely great time listening to my favorite LPs on the MoFi UltraDeck turntable," observes Paul Wilson, futureaudiophile.com, March 27, 2024.
"The sound quality was excellent, with superior dynamics and, on well-recorded LPs, the overall presentation was magnificent. I would categorize this as an ability to render a level of sonics that belies the turntable’s retail price. There was a real sense of ease and effortlessness in LP after LP I played."
10" Ultra Tonearm
Custom-developed and manufactured in the USA, the 10" Ultra tonearm uses smooth, high-quality ball bearings for low friction in the vertical and horizontal plane, so that all you hear is what is in the grooves. Cardas Audio wiring maintains signal purity from the head shell leads all the way through to the high-quality, gold-plated RCA connectors.
Isolated AC Synchronous Motor
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 the use of advanced dampening materials that decouple the motor from the rest of the turntable.
Anti-Vibration Feet and High-Mass Body
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.
Additionally, the 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.
"I Only Turned It Off Overnight"
"There was this 'togetherness' that drew me into the listening," notes Andrei L in his review for forums.stevehoffman.tv. "The consistency of the UltraDeck and UltraTracker in its performance across many music genres that I have in my vinyl collection made me decide that this is my last turntable. I felt at home with this deck, and in the last several days I only turned it off overnight."
"Although I'm within my 60 day home audition period, I can assure you that the Ultradeck is here to stay. At this level, one will have to spend far more for an uncertain performance outcome. Different? Yes. Better? I'm not so sure," reports Nels Ferre vinylmeplease, November 7, 2017.
"With the Ultradeck, MoFi has produced an American made turntable that's well engineered and built, looks great, and sounds sublime - and they brought it to market at a very reasonable price. I can see why it took so long to finally become available. The wait was well worth it," Ferre concludes.
1.3"-Thick Delrin Platter
The UltraDeck features a massive 1.3-"-thick 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
The hardened-steel inverted bearing system is designed for smooth, quiet rotational stability. The extremely low tolerance combination of steel, bronze, and sapphire – typically found in much more expensive turntables – will provide you many years of high-performance playback.
Choice of Three Optional Cartridges
You can order the UltraDeck without a phono cartridge, using one of your own. You can also order it with one of three superb MoFi cartridges.
The UltraTracker dual magnet MM cartridge surrounds its V-Twin motor with a damped billet aluminum body to provide superior bass definition and slam. The upgraded nude elliptical stylus has low tip mass for superior tracking and extraction of fine details.
The MasterTracker dual magnet MM cartridge features pure Ohno continuous-cast copper coils and a Micro Linear diamond stylus. The result is surgical precision, pinpoint accuracy, and a purist-based sonic picture of what was cut in the studio.
Uniquely voiced by lead MoFi Electronics engineer Allen Perkins, the UltraGold MC moving coil cartridge offers exceptionally wide frequency response, clear high-frequency transients, stunning dynamics, and incredibly rich detail.
MoFi Turntable Excellence
Drawing on 40 years of making records at Mobile Fidelity Sound Lab, the new MoFi Electronics division is focused on improving the sonic integrity of audio reproduction in the home. MoFi products are the result of multiple collaborations with some of the world’s best audio designers, stemming from decades of experience in the studio.
Created in collaboration with one of the world’s foremost turntable and tonearm designers, Allen Perkins of Spiral Groove, MoFi’s new turntables provide uncompromising playback of your vinyl collection and maintain the high standards of Mobile Fidelity Sound Lab.
"At The Top of the Class"
"It’s no accident that MoFi’s first turntable effort is at the top of the class," reports tonepublications.com. "John Schaffer, formerly of Wadia, has headed the project, bringing a tremendous amount of manufacturing and procurement knowledge to the mix. Even though Wadia was always a digital company, Schaeffer’s love for analog has always been apparent, as is his commitment to high quality…"
"Finally, all of this was accomplished right here in America. This table was not farmed out offshore to hit a price point. I think that is really impressive."
