About the AOS MC
The Rega AOS MC is a two-stage, pure analogue moving coil phono stage derived from the flagship Aura MC, housed in a custom half-width aluminum case for RFI shielding and rigidity. It features parallel-connected ultra-low-noise FETs in a symmetrical Class A topology, ensuring no bias current flows through the cartridge coil to preserve magnetic geometry. Adjustments for resistive loading (70, 100, 150, 400Ω), capacitive loading (1000, 4300pF), and gain (69.3dB or 63.5dB) are made via rear-panel DIP switches, with factory presets for Rega MC cartridges. Includes automatic standby (defeatable), self-adjusting servo for thermal stability, and exceptional RIAA accuracy. Designed for low-output MC cartridges, it delivers superior definition, detail, and vinyl realism without digital circuitry.
