Aura, reference MC preamplifier

The reference MC phono preamp, model Aura, represents the culmination of decades of electronics design development. We’ve created the ultimate fully adjustable, three-stage, symmetrical preamp designed purely to extract the best performance from your moving coil cartridge and vinyl playback system.

With a completely redesigned chassis, the Aura is dedicated to moving coil cartridges and makes no compromises. We have avoided incorporating any type of superfluous function that could obstruct the signal path and degrade sound quality. The Aura phono preamp incorporates notable and innovative design ideas. If you are a big vinyl fan, you should try the Aura MC.
