At last the Rega Aethos Amplifier is here. The Aethos stereo amplifier is housed in a 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. Features 156 W per channel into 6 Ω (125 W per channel into 8 Ω) Dual mono design 5 Line inputs Headphone socket Remote control Direct input Record out Pre-amp out Lifetime warranty* against manufacturer defects* As part of the design the Aethos has some useful features such as the switchable direct input and preamplifier output, to enable the new Aethos amplifier to be used 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. It doesn’t matter what kind of speaker you are using, Rega’s Aethos gives you fantastic sound quality with a highly musical, and excellent balanced presentation.
