A last the new Rega Aethos Amplifier is here.. Rega have taken all what they have learnt from amplifier design when making the Osiris they have now designed this the AETHOS. 

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 and 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. It doesn’t matter what kind of speaker you are using, Rega’s Aethos gives you a unique combination of engagement, enthusiasm and joy … Fantastic sound quality, highly musical, and excellent balance.
