Aura MC (REF)
The reference Aura MC stage is the culmination of decades of electronic design development. We have created the ultimate, fully adjustable, three-stage, all symmetrical pre-amplifier designed purely to extract the very best performance from your moving coil cartridge and vinyl playback system.
Design Innovation
Built into a completely re-designed custom case, the Aura is dedicated to moving coil cartridges and stays clear of any compromises. We have avoided including any superfluous functions as they obstruct the signal path and degrade the sound quality. The Aura phono pre-amp incorporates remarkable and innovative design ideas. If you are a vinyl connoisseur, then the Aura MC is an absolute must for demonstration.

Product Details
| First Stage | The first stage is a symmetrical, complementary class A amplifier, using parallel connected Linear Systems ultra-low noise FET transistors configured as a symmetrical compound pair input stage. The FET transistors ensure no bias current flows in the cartridge coil, protecting the magnetic geometry. The complementary FET transistors are graded and matched for optimal performance. This stage drives the passive high-frequency part of the RIAA equalisation stage. |
| Second Stage | The second stage is a symmetrical, class A, differential amplifier with a common base driver stage. This stage is used as the active amplifier in the low-frequency part of the RIAA equalisation stage. |
| Third Stage | The third stage inverts the signal to provide the balanced output, using the same circuit topology as the second stage. The power supply is a symmetrical, discrete tracking power supply using fast diodes and a low noise voltage reference. Each stage has its own localised power supply. 1% tolerance polypropylene capacitors are used in the RIAA EQ stages, and audio grade capacitors are used elsewhere. Gain, Mute, and Mono switching is done using high-quality relays. |
