Rega Aethos Amplifier released

The Rega Aethos stereo amplifier is now available.

We were pretty pleased with ourselves for spotting the new Rega Aethos at The Bristol Hi-Fi Show back in February when many others didn't.

Now, everyone can enjoy the fact that the Aethos is available to purchase.

Rega Aethos

If you're not familiar with the Rega Aethos, it is the British brand's new integrated amplifier which the firm promises to provide next-level performance.

The new custom-designed case is home to four 160 W 16 Amp output transistors per channel, delivering 156 W per channel into 6 Ohms. 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.

Improved Elex-R

The power amplifier used in the Aethos, Rega states, is an improved version of the one used in the Elex-R and Elicit-R.

Also borrowed from the Elex-R is the volume control and line amplifier, but improvements have also been made here too.

The Aethos uses the Linear Systems LSK389 FET and the well-respected RK27 'Blue Velvet' potentiometer.

The level and tracking between the left and right channels is set by the close tolerance parts in the pre-amplifier circuit and less by the actual potentiometer itself. The result is keeping the mismatch between channels due to volume control tracking irregularities to a minimum.

The Aethos has a switchable direct input and a pre-amplifier output making it a versatile partner with a wide variety of systems.

Furthermore, Raga has taken particular care not to obstruct the headphone output signal path by ensuring the speaker switching is performed by the output mute relay.

No Compromise

Rega Aethos

Rega's aim for a no-compromise amplifier also means that there is no DAC nor phono stage. Naturally, the company's Aura MC phono stage will be high on their recommendation list.

Price and availability

The Rega Aethos is available now for £2999.
