The AOS is a dedicated no compromise fully adjustable moving coil pre-amplifier using a circuit design based heavily on our award-winning Aura reference MC phono stage. Housed in a custom made Rega half width case, the AOS will deliver exceptional definition and greater realism to all of your recordings, bringing your favourite vinyl to life.
Designed to work with a wide range of moving coil cartridges it has plenty of gain for low output MC’s and excellent load adjustability making it the perfect partner for whichever Moving Coil you are using.
The AOS is a two stage “all analogue amplifier” with no digital control circuitry. The fully aluminium case screens the internal circuit from any stray RFI signals. Our designers have avoided including any unnecessary components or circuits that may degrade the signal path. The AOS incorporates many innovative design ideas including a self-adjusting servo control which compensates for any variations in ambient or operating temperature.
