Mobile Fidelity - UltraDeck Turntable

A Turntable Specifically Designed to Preserve the Delicate Analog Signal and Play Vinyl LPs With Utmost Accuracy: USA-Made Mobile Fidelity UltraDeck Offers True-to-the-Source Sound

The literal definition of the prefix "ultra" – extreme, or to an extreme degree – embodies the concept, construction, and performance of the Mobile Fidelity 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 USA at Mobile Fidelity's in-house factory in Michigan, 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 famous accuracy of Original Master Recordings – as well as faithfully recreate the music on any other LP you play.

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.

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 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.

“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 Reichart, 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.”
