Rega Aethos Integrated Amplifier

Power, Purity and Precision for the Discerning Listener

In the world of high-fidelity audio, where every component in the chain matters, the Rega Aethos Integrated Amplifier stands as a commanding presence. Designed and built in the UK, the Aethos reflects Rega’s decades-long commitment to musical integrity, minimalist engineering, and handcrafted quality. It’s an amplifier not just for those who listen to music—but for those who truly hear it.

A Bold Design Philosophy

The Aethos forgoes unnecessary frills in favour of a purpose-driven aesthetic. Its sleek aluminium casework and robust construction aren’t just visually striking—they also serve a practical role, offering optimal heat dissipation and durability. The front panel’s clean layout and solid metal controls provide a tactile connection to the music, reminding you that this is a piece of equipment built to be used and enjoyed.

Internally, the Aethos shares more in common with high-end separates than it does with traditional integrated amplifiers. Its dual mono layout, high-spec components, and oversized toroidal transformer are all hallmarks of a design that prioritises purity of signal and strength of delivery.

Class A/B Power with Grace and Control

At its heart, the Aethos operates in Class A/B, striking a balance between the warmth and fluidity of Class A and the efficiency of Class B. The amplifier is capable of delivering 125 watts per channel into 8 ohms, and an even more authoritative 156 watts into 6 ohms—more than enough to drive even the most demanding loudspeakers with ease and composure.

But it’s not just about raw power. The Aethos is celebrated for its speed, timing, and finesse. It delivers a sonic performance that’s immediate and gripping, yet always composed. Transients are lightning-fast, bass is taut and extended, and midrange detail emerges with exceptional clarity and nuance.

Designed for the Music

Rega has long held the belief that great sound should serve the music, not overshadow it—and the Aethos exemplifies this ethos. Whether you’re listening to the texture of a bowed double bass, the decay of a piano note, or the subtle brush of a cymbal, the Aethos reproduces music with a lifelike realism and emotional depth that draws you deeper into every recording.

It reveals the character of each track—without imposing one of its own.

Flexible Connectivity, Thoughtful Touches

While the Aethos is minimalist in spirit, it doesn’t compromise on functionality. It offers five line-level inputs, including a dedicated high-quality headphone amplifier, which is driven directly from the output stage via a relay. This ensures that even private listening is delivered with the same authority and musicality as loudspeaker playback.

The Aethos also features a preamp output, allowing easy integration into larger systems or future expansion with external power amps or active subwoofers.

Built in Britain, Made for Music

Every Aethos is hand-assembled in the UK, with Rega’s characteristic attention to detail and long-term reliability. This is not a mass-produced product—it’s a precision-built piece of audio equipment, made by engineers who are as passionate about music as the people who use it.

From component selection to circuit layout and final testing, every aspect of the Aethos is carefully considered to ensure it serves its sole purpose: to deliver music exactly as it was meant to be heard.
