"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
"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
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.
First, 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. The Studio Deck has a 3/4-INCH DELRIN® PLATTER.
Custom developed and manufactured in the USA, Mobile Fidelity’s Studio and Ultra Tonearms deliver the ideal balanced of rigidity and low tracking error so all you’ll hear is what is in the record grooves. These are not your Daddy's 9" arms. These are 10" arms for better tracking.
STEEL AND TEFLON INVERTED BEARING:
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.
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.

Optional StudioTracker Cartridge
MoFi cartridges are designed by looking back at where a record starts: On a lacquer cutting lathe like the model used at Mobile Fidelity Sound Lab. StudioTracker features a V-Twin dual-magnet generator that mirrors the layout of the cutting head that originally made a record’s grooves.
V-TWIN DUAL-MAGNET GENERATOR
Employing two low-mass, powerful magnets aligned in a V formation parallel with the stereo record grooves, StudioTracker accurately extracts precious details from your LPs.
ELLIPTICAL DIAMOND STYLUS
With a polymer body and elliptical stylus, StudioTracker offers surprising bang-for-your-buck value and a rich sound distinguished with a smooth, slightly forgiving top end.
