Mobile Fidelity Electronics MasterDeck Turntable at Vinyl Sound Toronto Canada

The MasterDeck is a reference-grade belt-drive turntable from Mobile Fidelity Electronics (MoFi Electronics, Ann Arbor, Michigan, USA), available at Vinyl Sound in Toronto, Canada. Designed by Allen Perkins — one of the most respected turntable engineers in the high-end audio industry and founder of Immedia — the MasterDeck is handcrafted in limited batches at MoFi's Ann Arbor factory and represents the most ambitious expression of Mobile Fidelity Sound Lab's decades-long commitment to faithful vinyl reproduction. At its core is a three-phase brushless DC synchronous motor with optical speed regulation, a 1.75-inch hybrid Aluminum-Delrin platter weighing 14.35 lbs, and an all-new 10-inch dual-pivot carbon-fiber tonearm with removable headshell and premium Cardas Audio internal wiring. The MasterDeck supports 33.3, 45, and 78 RPM playback with fine-speed trim adjustment and rides on Harmonic Resolution Systems isolation feet engineered to provide 5.5 degrees of vibration freedom.

10-Inch Dual-Pivot Carbon-Fiber Tonearm with Cardas Audio Wiring

The MasterDeck's tonearm is a purpose-designed 10-inch dual-pivot carbon-fiber assembly that combines the low-friction bearing characteristics of a unipivot with the lateral stability of a gimbal, resulting in a hybrid unipivot/gimbal architecture that tracks demanding groove modulations with exceptional precision and composure. Carbon fiber is used throughout the arm tube for its high stiffness-to-mass ratio, keeping the structure rigid against vibration while minimizing the added mass that would otherwise reduce tracking ability at the headshell. A removable headshell allows straightforward cartridge swapping and azimuth optimization without tools, and the arm provides full adjustment of vertical tracking angle, overhang, and anti-skate to accommodate cartridges weighing between 5g and 14g. Internal wiring is supplied by Cardas Audio, a specialist in audiophile-grade litz copper conductors, ensuring that the low-level signal from the cartridge reaches the phono stage with minimum coloration and electrical interference. An 18mm overhang and 22.8-degree offset angle place the stylus on a geometry optimized for the 10-inch effective length, minimizing tracking error across the playing surface of both standard LPs and 78 RPM shellacs.

Precision Motor, Platter, and Bearing System

The MasterDeck is driven by a three-phase brushless DC synchronous motor mounted in an isolated sub-chassis to prevent mechanical noise and vibration from reaching the platter bearing or tonearm. An optical sensor monitors platter rotation in real time and feeds corrections back to the motor controller, maintaining speed accuracy across all three playback rates — 33.3, 45, and 78 RPM — with a fine trim adjustment that allows users to dial in exact speed for individual records or cartridge compliance requirements. The 14.35-lb platter is machined from aluminum and coated with Delrin, an acetal resin chosen for its self-damping properties and acoustic impedance that couples efficiently to vinyl while absorbing platter resonance that would otherwise color playback. The platter spins on an Encapsulated Spiral Groove Inverted Bearing, a precision-machined system in which the spindle is fixed to the plinth and the bearing housing rotates around it, shifting the load-bearing contact point to minimize friction, reduce wear over decades of use, and produce an exceptionally smooth and stable rotational characteristic. The entire assembly sits on Harmonic Resolution Systems isolation feet that provide 5.5 degrees of mechanical freedom, effectively decoupling the MasterDeck from floor-borne vibration and acoustic feedback that would otherwise modulate the stylus in the groove.

Frequently Asked Questions

What is the MoFi Electronics MasterDeck turntable?

The MasterDeck is a reference-grade belt-drive turntable from Mobile Fidelity Electronics, handcrafted in limited batches in Ann Arbor, Michigan, USA, and designed by Allen Perkins. It features a three-phase brushless DC synchronous motor with optical speed regulation, a 14.35-lb hybrid Aluminum-Delrin platter, a 10-inch dual-pivot carbon-fiber tonearm with Cardas Audio internal wiring, and Harmonic Resolution Systems isolation feet. It plays 33.3, 45, and 78 RPM records with precision fine-speed trim adjustment, and is available at Vinyl Sound in Toronto, Canada.

How does the MasterDeck compare to the Rega Planar 10 and the Clearaudio Concept?

The MasterDeck occupies a distinct position relative to both competitors. Against the Rega Planar 10, which uses a lightweight skeletal plinth philosophy, a hand-selected low-noise AC motor, and Rega's RB Apheta-matched tonearm, the MasterDeck counters with a far heavier 14.35-lb Aluminum-Delrin platter for greater rotational stability, an optically regulated brushless DC motor for active speed correction rather than passive AC frequency dependence, and HRS isolation feet that address floor-borne vibration at a level the Rega's lightweight construction cannot match. Against the Clearaudio Concept, a belt-drive design with a magnetic bearing and Clearaudio's Concept tonearm, the MasterDeck offers a 10-inch arm versus the Concept's typically shorter geometry, a more complex inverted bearing system, three-speed 78 RPM capability, and the prestige of limited-batch USA manufacture by a designer of Allen Perkins' standing. Neither competitor combines optically regulated brushless DC drive, HRS isolation, a 10-inch carbon-fiber dual-pivot arm with Cardas wiring, and 78 RPM support in a single handcrafted package.

What is the dual-pivot tonearm design on the MasterDeck?

The dual-pivot tonearm on the MasterDeck is a hybrid unipivot/gimbal design in which the arm pivots on two bearing points rather than one. A conventional unipivot arm balances on a single point, giving it exceptional freedom of movement and low bearing friction but requiring careful setup to prevent lateral instability. A gimbal arm uses two or more bearing points for rock-solid lateral control but can introduce bearing friction. The MasterDeck's dual-pivot architecture combines both approaches, achieving the low-friction, free-moving character of a unipivot in the vertical plane with the lateral stability of a gimbal in the horizontal plane. The result is a tonearm that tracks groove modulations with precision and composure across both axes without the setup sensitivity of a pure unipivot design.

What does the Harmonic Resolution Systems isolation do on the MasterDeck?

The Harmonic Resolution Systems isolation feet beneath the MasterDeck are purpose-engineered vibration control devices that provide 5.5 degrees of mechanical freedom between the turntable chassis and the supporting surface. This means the feet absorb and dissipate energy arriving from the floor — footfall, low-frequency room modes, and acoustic feedback from speakers — across multiple axes simultaneously rather than in a single plane. In a vinyl playback context, any mechanical energy that reaches the platter or tonearm modulates the stylus in the groove and adds spurious low-level noise to the signal. The HRS feet prevent this energy from reaching the MasterDeck's precision bearing and tonearm, preserving the low-level detail and dynamic range that the MoFi MasterDeck's engineering is designed to retrieve.

Can the MasterDeck play 78 RPM records?

Yes, the MasterDeck supports 78 RPM playback in addition to 33.3 and 45 RPM. A three-position speed selector switches between all three formats, and a precision fine-trim adjustment allows exact speed calibration for individual records. Playing 78 RPM shellac records at correct speed requires a dedicated 78 RPM stylus with a larger tip radius than a standard LP stylus, so a compatible cartridge or a second headshell fitted with a 78-appropriate stylus is recommended. The MasterDeck's removable headshell makes switching between a standard LP cartridge and a 78 RPM setup straightforward.

Where can I buy the MoFi Electronics MasterDeck in Toronto or Canada?

The MoFi Electronics MasterDeck turntable is available at Vinyl Sound, an authorized Mobile Fidelity Electronics dealer in Toronto, Canada.
