ORIGIN LIVE Ultra DC Motor Kit



Calculate Shipping

The Ultra motor kit offers owners of almost all turntables the advanced technology & reference performance used in our Resolution Turntable, with components costing 100 times more than those used in the standard motor kit this is a true reference option. Contains improved control box and DC100 motor.

Universal Ultra DC Motor Kit & Turntable Power Supply


Front view of box housing the voltage regulator and speed control switch. Comes prebuilt with all leads and plug connectors. No soldering required - all you need to do is install the DC motor.

Dimensions of regulator and speed control box (H x W x D) 50mm x 110mm x 180mm.

Power supply upgrade includes high-grade DC100 motor, fully balanced upgrade transformer housed in a large enclosure, regulator and speed control box, strobe card, full instructions, etc.

Design and Characteristics

The Ultra power supply regulator builds on the success of the Advanced power supply and includes the same load compensating design that results in such good speed stability. However, a number of important advances in the Ultra design result in a clearly audible upgrade.

The reasons why superior power supplies have such an audible effect on performance have been well documented - it is well known, for example, that they reduce variations in motor speed and, more importantly, vibration of platter and arm. What may not be so generally appreciated is that speed variation is measured over too long a period to provide more than a guide to wow and flutter, and that platters also suffer a momentary slowing under load which is so small it can hardly be measured. The cartridge amplifies this effect 100,000 times, resulting in an appreciable loss of dynamic impact, especially in the bass region. To overcome this, some decks use a very high mass platter but this "solution" has its own drawbacks, producing a thick, clinical and lifeless sound. A better solution is to make the motor capable of responding powerfully and instantaneously to passages that increase the dynamic load on the deck. This is one aspect addressed by the Ultra power supply.

Another factor often not fully appreciated is that a voltage regulator must not be adversely affected by the background electric and magnetic field and high internal power fluctuations of the motor itself. A good power supply must be able to absorb such dips and surges in load, while adjusting to deliver copious and precise power with great speed.

The Ultra power supply is designed to meet these requirements and the results are obvious upon listening.


Component upgrades

Many aspects of component specification have been upgraded, including low impedance/low leakage capacitors, highly specified diodes, special LED, paralleled transistors carefully matched to within 0.1 V.

Circuit upgrades

The circuit design has been considerably refined to:

1. Reduce electrical noise
2. Reduce response time
3. Increase current delivery

DC100 Motor

As of August 2003, all Ultra and Advanced kits employ our new DC100 motor. This is a higher torque, near silent running motor with lower vibration than the one used previously.

DC200 Motor
An extremely high performance motor building further on the improved characteristics of the DC100, with clearly audible sonic benefits. This motor is available as an optional upgrade to the Ultra kit.
