General:
The Ultradeck is an award-winning turntable from MoFi Electronics.

A beautiful custom tonearm made right here in the USA really sets this turntable apart from the others. Its use of anti-vibration feet by HRS from the factory is also a nice touch. 

It utilizes a three-layer construction made of aluminum and MDF for proper dampening. This is not often found in turntables at this price point.

We paired this turntable with a brand new Sumiko Blue Point No.3 High-Output MC Cartridge ($499). It will come to you calibrated using our 12-step process ($390) for maximum performance.

From MOFI:
The word “Ultra” is synonymous with Mobile Fidelity Sound Lab's philosophy. It represents our extreme pursuit of the highest level of reproduction of recorded sound—beyond the status quo—to provide music lovers with the experience of hearing the Original Master Recording in their home. Whether you're enjoying a standard LP or one of our UltraDisc One-Step limited-edition records, UltraDeck will deliver faithful playback of what's in the grooves.

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.

ULTRA TONEARM
Custom-developed and manufactured in the USA, the 10-inch Ultra tonearm uses smooth, high-quality ball bearings for low friction in the vertical and horizontal plane so all you hear is what is in the grooves. Cardas Audio wiring maintains signal purity from the headshell leads all the way through to the high-quality, gold-plated RCA connectors.

ISOLATED AC SYNCHRONOUS MOTOR
Our 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
UltraDeck features three aluminum plates 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.

1.3-INCH DELRIN® PLATTER
UltraDeck features a massive 1.3-inch Delrin® platter. The increased mass creates blacker sonic backgrounds and a lower noise floor. Delrin® is a next-generation polymer developed by Dupont. In the world of audio, Delrin's® highly crystalline structure presents a wonderful impedance match to vinyl records, effectively grounding unwanted noise and keeping it away from the stylus.

HARDENED-STEEL INVERTED BEARING
Our hardened-steel inverted bearing system is designed for smooth, quiet rotational stability. The extremely low tolerance combination of steel, bronze, and sapphire—found in much more expensive turntables—will provide you many years of high-performance playback.

Testing Process:
First we try to identify any mechanical issues, particularly in the tonearm bearings. We check for freedom of movement or any resistance on both the horizontal and vertical range. There is a quick test for this which involves placing the table on its front edge and allowing the arm to swing freely like a pendulum. We then make any adjustments necessary to achieve minimal resistance and sometimes adjust the bearing pressure. On gimbal tonearms we inspect the cone tip with a magnifier.

We then assess the platter speed using one of several methods, the most accurate being playing a test tone on a test record and measuring the frequency output with a frequency counter or oscilloscope. We also utilize test equipment to measure the wow and flutter to ensure it is within spec. We do this for all speeds available for that particular model (33 RPM, 45 RPM, 78 RPM).

Adjustments are then made to achieve proper speed which will vary depending on the turntable's drive design. Some require an adjustment of an internal or external potentiometer, some will require a pulley or motor adjustment. We also inspect the platter bearing to ensure it is properly lubricated, keeping in mind that some bearings don't require lubrication at all

We then inspect the power supply and address any issues with overworked capacitors, particularly on Linn and later Thorens machines which tend to need attention.

On fully mechanical vintage tables like the Thorens TD-124 and Garrard 301/401 we will go thought the entire mechanism. Then replace any worn parts and lubricate all components necessary to ensure smooth operation, speed change, and low mechanical noise. 

When fitting a new phono cartridge we will go through our detailed calibration process which can involve as many as 12 steps depending on the tonearm design. We perform this work on our custom turntable calibration rig which was developed in-house.

Some of these steps include:
• Pivot to Spindle Adjustment
• Tracking Force
• Anti-Skate
• Tonearm Height
• Lifter Height
• VTA (Vertical Tracking Angle)
• Azimuth
• Stylus Distance and Overhang

We then do a critical listening test using our test records and our test system to ensure proper sonics.
