The Aethos stereo amplifier is housed in a brand new, custom-designed case. Employing four 160 W 16 Amp output transistors per channel, this delivers 156 W per channel into 6 Ω. The Aethos is a dual-mono design using a custom wound toroidal transformer & regulated supplies for the sensitive amplification and driver stages. The pre-amplifier stage uses class-A discrete circuitry throughout. The Aethos is a no-compromise product with one goal, to deliver your music as faithfully as possible.
Rega's time, effort, and money was been spent on developing the circuit and construction while utilizing the highest specification of components throughout.
As part of the Aethos, Rega included useful features such as the switchable direct input and preamplifier output, to enable it for use in a wide combination of systems. The headphone socket has been integrated such that the speaker switching is performed by the output mute relay as so not to obstruct the signal path and degrade the sound quality.
Rega has taken the design concepts underpinning the multi-award-winning and hugely successful Elex-R and Elicit-R and propelled the performance to the next level. Rega designed the Aethos with a 125watt dual-mono design and features such as a fully discrete FET-based line amplifier, polypropylene capacitors throughout the signal path.
Additionally, Aethos is fitted with K-Power reservoir capacitors, power amplifier regulated supply, and a high current output stage comprising of four 160w Sanken output transistors per channel.
