MoFi Electronics UltraDeck

Overview

The MoFi Electronics UltraDeck is a serious belt-drive turntable developed with acclaimed designer Allen Perkins, built to draw quiet, dynamic and detailed performances from your records. It sits in the heart of the MoFi turntable range, above the StudioDeck and below the PrecisionDeck, and it reflects the mastering-house pedigree of Mobile Fidelity Sound Lab in its engineering priorities of low noise and honest tonal balance.

At its core is an isolated 300 RPM AC synchronous motor decoupled from the plinth to keep vibration away from the record surface, paired with a substantial 1.3 inch Delrin platter weighing 6.8 lbs for speed stability and resonance control. The 10 inch straight aluminum tonearm rides on a precise gimbal bearing with 18mm overhang and a 22.8 degree offset, and the MDF and steel plinth with adjustable feet gives the whole deck a stable, level foundation. Wow and flutter is rated at 0.017 to 0.025 percent with a signal to noise figure of 74dB.

This deck is sold here without a cartridge, which lets you choose the sound you want. It accepts the MoFi MasterTracker, UltraTracker or UltraGold and other standard half inch mount cartridges. It suits the listener who wants a refined, musical analog front end and enjoys tuning the system to taste rather than accepting a fixed package.

How the UltraDeck Compares

MoFi UltraDeck vs MoFi PrecisionDeck Fender

The PrecisionDeck sits a step up in the MoFi range and offers a more elaborate platter and tonearm arrangement aimed at even lower noise and greater resolution. The UltraDeck delivers the core MoFi character of quiet, musical playback in a more accessible package. Choose the PrecisionDeck if you want the additional refinement at the top of the line. See the MoFi PrecisionDeck Fender.

MoFi UltraDeck vs Audio-Technica AT-LP7X

The AT-LP7X is a fully manual belt-drive deck aimed at listeners who want a compact, straightforward analog front end. The UltraDeck emphasizes a heavier Delrin platter and an isolated synchronous motor for a more substantial, resonance-controlled foundation. Both are manual belt-drive designs, so the choice comes down to mass, tonearm character and how you like to tune your system. See the Audio-Technica AT-LP7X.

MoFi UltraDeck vs Thorens TD 403 DD

The Thorens TD 403 DD is a direct-drive design that provides immediate speed lock and a clean, low-maintenance approach. The UltraDeck takes the belt-drive route with an isolated motor and a massive Delrin platter to shape its own quiet, flowing presentation. Pick based on whether you prefer direct-drive immediacy or the isolated belt-drive character. See the Thorens TD 403 DD.

Recommended Cartridge, Phono Stage and Amplifier

Because the UltraDeck ships without a cartridge and a turntable needs phono equalization and gain, here is a complete path to a finished, high-end analog system.

• MoFi MasterTracker MM Cartridge The MasterTracker is MoFi's top moving magnet cartridge and mounts cleanly on the UltraDeck's half inch arm, giving a voiced-in-house match with detailed, dynamic tracking.
• MoFi UltraPhono Pro Phono Stage This single-input MM and MC phono stage provides the equalization and gain the turntable needs, keeping the whole front end within the MoFi family for a coherent result.
• MoFi MasterPhono Phono Stage For the reference route, the MasterPhono offers an extensive adjustable loading range so you can fine-tune whichever MM or MC cartridge you mount on the UltraDeck.
• Audiolab 6000A MKII Amplifier This integrated amplifier drives passive speakers and completes the system, since MoFi does not make amplifiers and the SourcePoint speakers need separate amplification.
• MoFi SourcePoint 8 Bookshelf Speakers Designed by Andrew Jones around a concentric point-source driver, these stand mounts give wide, even dispersion and a true point source to reveal what the UltraDeck retrieves.
