Features
Ultra Tonearm: Custom-developed and manufactured in the USA, the MoFi UltraDeck+'s 10" 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.
UltraTracker Cartridge (MM): The UltraTracker Cartridge (MM) features a V-Twin dual-magnet generator that mirrors the layout of the cutting head that originally makes a record's grooves. Employing two low-mass, powerful magnets aligned in a V formation parallel with the record grooves, UltraTracker features excellent tracking ability.
- Well-Damped Billet Aluminum Body: The well-damped billet aluminum body controls resonances for tight, accurate bass reproduction. UltraTracker delivers finely tuned wide-bandwidth audio, with extension at both frequency extremes and no smearing of detail.
- Nude-Elliptical Diamond Stylus: By using a nude-elliptical diamond stylus, UltraTracker easily tracks complex dynamic passages. You'll hear superb detail and experience musical emotionalism that will send shivers down your spine.
- This turntables come with the tracking force preset by the factory. Using this predetermined factory setting (indicated by the pre-installed yellow tape) prevents the need for a force gauge. Just place the counterweight properly on the back of the tonearm (directly behind the pre-installed yellow tape) and you are done. No need to balance or perform any other steps for tracking weight. Do not remove the yellow tape until the counterweight is installed and you have tested playback.
- If the yellow tape is removed before installing the counterweight, then the factory setting is lost and a force gauge must be used. The cartridge requires the tracking force be set between 1.8g and 2.2g. Using a tracking force gauge is necessary because the counter weight has no adjustment markings.
Isolated AC Synchronous Motor: The 300 RPM 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.
1.3" Delrin Platter: The UltraDeck+ turntable features a massive 1.3" 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 System: The UltraDeck+'s hardened-steel inverted bearing system is designed for smooth, quiet rotational stability. The extremely low tolerance combination of steel, bronze, and sapphire will provide many years of high-performance playback.
Constrained Layer Dampening: The UltraDeck+ turntable features an aluminum plate carefully bonded to an MDF body to add mass and eliminate tonal coloration, maintaining the true sound found on the record.
Anti-Vibration Feet: 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 the UltraDeck+ turntable from bad vibrations.
RCA Connections: Connection to the phono input of your amplifier can be made with connecting cables of your choice through the turntable's gold-plated stereo RCA phono jacks and grounding screw. The UltraDeck+ turntable comes supplied with a 49" stereo RCA cable with ground wire.
Dust Cover: The MoFi UltraDeck+ comes supplied with a hinged cover to prevent dust build-up on the turntable.

Probably the best turntable out there right now for the money. It punches way above its price range. I've owned lots of turntables over the past 40 years (some more expensive) and this one is the best. Comparing this to a Rega? Not a fair comparison- this destroys them.
