The Aos MC has perfect timing and delivers the musical goods in a compelling fashion

The Ear

Pure Analogue

The Aos is an “all analogue amplifier” with no digital control circuitry. The fully aluminium case screens the internal circuit from any stray RFI signals. Rega 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.

First Stage

The first stage is a symmetrical, complementary class A amplifier, using Linear Systems ultra-low noise FET (Field Effect Transistor) transistors. The use of FET transistors ensures there is no bias current flowing in the cartridge coil so as not to upset the delicate magnetic geometry of the cartridge. The input circuit configuration also alleviates the use of any coupling components between the cartridge output and the input stage FET transistors, which would degrade thesound. The complementary ultra-low noise FET transistors are carefully graded and matched for optimum 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 is also used as the active amplifier in the low-frequency part of the RIAA equalisation stage.

Who is this for?

The Aos MC has perfect timing and delivers the musical goods in a compelling fashion, if you really want to know what’s cut into the groove wall take your favourite vinyl down to your local Rega dealer at the earliest opportunity.

Without ever feeling like there is a part of the frequency range being over emphasised, the Rega makes the critical bits of the music you are listening to tangible and present in a way that simply sounds right
