The literal definition of the prefix "ultra" — extreme, or to an extreme degree — embodies the concept, construction, and performance of the Mobile Fidelity Electronics UltraDeck turntable. Dovetailing with the purist-minded philosophy long espoused by the Mobile Fidelity Sound Lab's Sebastopol, California studio, the Stereophile Analog Product of the Year Award-winning and Class B Recommended UltraDeck is devoted to exceptionally quiet, true-to-the-source playback of vinyl LPs without adding any of its own colorations
But it goes even further by taking critical measures to ensure unwanted noises and ruinous vibrations remain kept from the critical stylus/record interface. Proudly made in the U.S.A. at Mobile Fidelity's in-house factory in Michigan, featuring a pre-installed MoFi MasterTracker MM phono cartridge, and designed in collaboration between Mobile Fidelity engineers and turntable expert/Spiral Groove founder Allen Perkins, the sturdy 25-pound UltraDeck is a world-class component eminently qualified to reproduce the accuracy of the music on any LP you play.
Pre-mounted with a MasterTracker cartridge for stellar plug-and-play convenience, UltraDeck immediately stands out via its super-sturdy, unshakable physicality that includes a 1.3-inch Delrin platter — 75 percent thicker than that on Mobile Fidelity's StudioDeck model — that delivers deep-black backgrounds and a fantastically low noise floor. Delrin is chosen due to its natural impedance match with vinyl. Speaking of being made for LPs: UltraDeck's 300RPM isolated AC synchronous motor offers excellent speed stability for stellar pitch accuracy and rhythmic drive. Better still, UltraDeck's constrained layer dampening build — comprised of three aluminum plates bonded to the MDF body — adds extra mass, eliminates coloration, and contributes to increased stability. It's just another way UltraDeck takes its purpose to the extreme. Ditto its use of ester-based bearing grease, which lends to the 'table's extreme quiet.
Mobile Fidelity's engineering prowess extends to the custom-developed Ultra tonearm, a 10-inch straight aluminum gimbaled bearing design whose rigidity and tracking prowess translate into hyper-accurate information retrieval. Ultra tonearm also uses Cardas Audio wiring to maintain signal purity from the head shell leads all the way through the RCA connectors. Adjustable tracking force, VTA, azimuth, and enhanced anti-skate grant you limitless options for tweaks and adjustments. A hardened-steel inverted bearing system complete with a sapphire thrust pad provides UltraDeck wonderfully smooth, rotational stability while anti-vibration feet — co-developed with the engineering team at Harmonic Resolution Systems, the world leader in vibration isolation — further shield UltraDeck from disruptive resonances. Again, everything circles back to preserving the genuine sound locked in the grooves of your LPs. It's why Mobile Fidelity even outfits UltraDeck with high-quality gold-plated connectors shielded by a copper foil box to prevent airborne RF noise and, as a bonus, includes a removable, hinged dust cover to guard against debris when the 'table isn't spinning records.
On this edition of UltraDeck, that task will be enhanced by the MasterTracker cartridge. Fine-tuned by Mr. Perkins and Mobile Fidelity, and hand-built in Japan with housing milled from solid aluminum billet in the USA, MasterTracker traces LP groove walls with surgical precision and stopwatch accuracy. Equipped with pure Ohno continuous-cast copper coils and a trademarked Micro Linear diamond stylus – shaped just like a lathe's cutting head – this instrument mines the seemingly limitless amounts of information embedded in vinyl's microscopic nooks and crannies, presenting music with grand-scale cinematic scope and three-dimensional detail. Afforded the lightest-weight magnets of any cartridge in Mobile Fidelity's Tracker Series, MasterTracker plays with degrees of openness, clarity, and dynamics normally attributed to moving-coil cartridges. And its well-damped billet aluminum body yields payoffs you'll immediately hear: Unshakable reproduction of supremely complex passages and taut, edge-free bass.
Indeed, when it comes to enjoying and connecting with your music, you shouldn't settle. UltraDeck means you no longer have to do so. This is high-end analog as it's always been meant to be experienced.
"The [Mobile Fidelity UltraDeck] had stronger energy, achieved bigger dynamic swings, and was more detailed than comparatively priced 'tables... It presented me with an infectious, easy-flowing, liquid vitality that distinguished it from all its competition."
—Herb Reichert, Stereophile, Product of the Year and Class B Recommended Product
"[The] MoFi Electronics UltraDeck+ and StudioPhono system does its makers proud. It's bound to please a broad range of music lovers, who may or may not (yet) consider themselves audiophiles. Bottom line: The UltraDeck is a smartly conceived and finely honed design that's already earning its place as an instant classic."
—The Absolute Sound, cover story
"Given its development connections, I had a feeling MoFi's UltraDeck would be good, but am astonished by just how capable it is as it delivers plenty of bang for your buck at the price."
—Adam SmithHi-Fi Choice, Editor's Choice and five-star review
"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."

Control That Extends from the Mastering Studio to the Factory to Your Home
Prestige doesn't come easy — or cheap. To meet all its specific needs and demands, Mobile Fidelity established a new, dedicated facility in Michigan to build the majority of its products in the USA. While an uncommon and expensive endeavor in today's audio industry, in-house manufacturing is the only way to maintain total quality control and create products that live up to the exacting standards Mobile Fidelity established over the past four decades with music releases. The approach cuts both ways, giving you the security and confidence that the Mobile Fidelity product(s) you own is built to — and built to perform at — the highest specifications.
