MoFi UltraDeck +M Turntable. New Reference at an Entry Cost.



Product Description

MoFi (Mobile Fidelity) UltraDeck +M Turntable. New Reference at an Entry Cost.

Now at True Audiophile

"We have been searching for years to find less expensive TT's that fit into budgets easier, yet provide enormous sonic benefits. Subliminally, maybe we were just waiting on Mofi. Mofi has been known worldwide for the master pressing and limited releases. They knew if they were going to present the world with a TT/cart they had to get it right. Luckily for all audiophiles out there they did" -- TA

This is the NEW +M Package which includes the MasterTracker Cartridge for only $200 more than the standard UltraDeck. A $300 savings.

Just in From Stereophile about the +M package:

"one of the most natural-sounding record players available for under $5000. Highly recommended."

"The arm has an effective length of 10 inches. Most models on this price range are 9 inches. The extra inch is important. All pivoting arms have tracking error. The longer the arm, the more gentle the arc as the arm travels the playing surface. The more gentle the arc, the lower the tracking error. The arm height is easily adjustable as is the azumith, or left/right tilt of the cartridge when viewed from the front. The appropriate Allen keys are supplied. Additionally, the arm has bespoke wiring from Cardas from the cartridge clips to the output jacks... One last detail that probably won’t be spotted in pictures: there’s an O ring between the arm tube and the headshell to assist in isolating the stylus from unwanted vibration.

Antiskate is set by the common “weight on a string” arrangement. What is different here is that the setting isn’t determined by the tracking force, but by the weight of the cartridge being used. This actually makes perfect sense, as the weight of the cartridge combined with the “pull” of the groove will give it momentum as the stylus tracks the groove. The anti skate system provides resistance to this momentum so that the stylus tracks the record with equal force on both groove walls. It makes sense to me that the weight of the cartridge would have a larger effect than tracking force in regards to properly setting antiskate.

The square power button is a nod to Mofi’s heritage. It’s fashioned after the buttons on the big Studer professional open reel decks in their California studio...

Taking into account the high level of performance and engineering MoFi has achieved with the Ultradeck, I suspect they’ve got a hit on their hands. Compared to it’s likely competition, the Technics SL-1200G, Rega P6 as well as various models from Pro-Ject and Music Hall, the Ultradeck is as different as those models are from each other. Whether or not the Ultradeck is right for you will come down to what you value in a turntable.  I can assure you that the Ultradeck is here to stay." -- Vinyl Me, Please. Nels Ferre

"Coming from a musical family, I was no stranger to various reel-to-reel decks since I was very little. I know very well the sound of a 1/4" tape. So when I experienced my first needle drop with the UltraDeck and UltraTracker, what I heard was the sound that I knew too well. I won't get into surgical details of what it sounded like, but I'll mention that there was this "togetherness" that drew me into the listening. No over-exaggerated treble (and bass for that matter), plenty of detail but not over-analytical at the same time, smooth and involving, this was the sound of a well recorded master reel that I rarely experienced with a turntable before. Don't get me wrong, I know what an SME table can do, however 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...Few more day in -- no more issues. Spinning nonstop and it works and sounds fantastic...The sound is getting even more enjoyable. I forgot to mention another great thing about the UltraDeck/UitraTracker combo -- it is very forgiving. The inner groves on all records sound terrific. The scratched records are very listenable. And even the bad pressings sound somewhat okay, definitely more enjoyable that with my past setups, where some cartridges cost more than my new MoFi table." -- Andrew L., Hoffman forums (a real user)

"...the UltraDeck’s lucidity and tonal addictiveness...these command the centre of the soundstage, guitars to the right and a clarinet enter and exit on cue flawlessly if your vinyl spinner’s pitch and timing are spot on...I used the UltraDeck long after I stopped taking review notes. Record after record was played on its Delrin platter totally for enjoyment, not enlightenment. I suspect fortunate buyers astute to this model’s sonic prowess will do the same and I can’t fathom a better reason to own an UltraDeck.--Stereonet/Outstanding Performance Award

Drawing on five decades of making the world’s best-sounding records at Mobile Fidelity Sound Lab studios, focusrd on improving the sonic integrity of home-audio reproduction. Each product is the result of collaboration with some of the industry’s finest engineers and stems from years of studio experience. Our turntables, cartridges, and phono preamplifiers are designed to spotlight what Mobile Fidelity Sound Lab continues to do with its famous Original Master Recordings: Getting you closer to what the original artist intended.

Designed in collaboration with one of the world's foremost turntable and tonearm designers, Allen Perkins of Spiral Groove, Mobile Fidelity turntables provide uncompromising playback of your vinyl collection and maintain the high standards of Mobile Fidelity Sound Lab.

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.

This is for the UltraTracker which is MoFi Reference. Lets look at the parts that set these Turntables apart.


The intent is for the LP to have maximum content with the platter. MoFi actually listened to over 30 formulations of the DuPont Delrin to find the one that sounded the best. Yes, they found that really it does make a difference. The material we chose has a nearly identical mechanical impedance with vinyl. This means that any surface noise tends to literally get drained away through the LP and then the platter.

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.The UltraDeck Platter is 6.8 lbs.


Custom-developed and manufactured in the USA, the 10-inch 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. These are not your Daddy's 9" arms. These are 10" arms for better tracking.


MoFi 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. 


MoFi 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.


UltraDeck 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.


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.

Here's a quick guide to what the UltraDeck has over the StudioDeck:

  • The tonearms look identical but there are some differences:
    • The Ultra has better bearings for less friction in both the horizontal and the vertical planes. Less friction equals better tracking.
    • Cardas wiring is used internally in the Ultra arm.
    • The Ultra arm has a special internal damping material to make it even less resonant.
  • The platter is much beefier on the Ultra. This is important in the design since the material chosen (a unique formulation of Delrin) has the same mechanical impedance as the vinyl that LP’s are made from. You'll see mentioned in most any review of either table how quiet they are. Surface noise is much less apparent than on competing designs. The reason is that the platter literally drains away surface noise. The larger platter on the Ultra does so even more effectively. More mass also equals a more stable rotation.
  • The Ultra also makes more comprehensive use of what we call Constrained Layer Damping. This is the combination of the aluminum top plates mated to the wood (MDF) base. It makes the Ultra a more stable and inert chassis for the entire unit to rest on.
  • The cartridge is a significant upgrade (a $300 retail difference). While the Studio cartridge is extremely good for it’s price range, upgrading to the Ultra represents a clearly audible benefit.
  • The Ultra has gold-plated output connections.
  • The headshell is aluminum.

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.


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.


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.
