Feliks Audio EOS

Feliks Audio Eos – Immersive Beauty

The Feliks Audio Eos is the new flagship headphone amplifier from Feliks Audio and the company’s first amplifier designed to drive both headphones and loudspeakers. Drawing on more than 25 years of experience in premium tube amplifier design, the Eos combines the renowned 6SN7 driver tubes with 300B power tubes to deliver an exceptional blend of power, refinement and musicality.

Designed as the ultimate centerpiece of a high-end listening system, the Eos offers a remarkably low noise floor, an exceptionally wide frequency response and tremendous output power. It is capable of effortlessly driving demanding high-impedance headphones while remaining quiet and controlled enough for highly sensitive headphones and even IEMs.

Compared with the previous flagship Envy, the Eos represents a significant technical step forward. Its 10x lower noise floor enables an exceptionally clean and transparent presentation, while the wider frequency response brings out more subtle detail and ambience in recordings. The output impedance has also been reduced by half, allowing the Eos to comfortably handle headphones with impedances as low as 10 ohms.

The Eos is equally impressive as a preamplifier. Its dedicated RCA and XLR preamp outputs benefit from a substantially wider frequency range and lower noise, making it an excellent control center for a complete high-end audio system.

Built for versatility

Feliks Audio has given the Eos a new level of functionality without compromising its analogue character. A clear integrated display provides important information including amplifier uptime, operating temperatures and tube health, while the supplied remote control makes everyday operation effortless.

Gain and output selection can be adjusted directly from the interface, allowing the Eos to be optimized for different headphones and system configurations.

For the first time in the Feliks Audio range, the amplifier also features speaker outputs, giving the Eos the ability to drive loudspeakers with authority. This makes it far more than a dedicated headphone amplifier: it can serve as the central amplification component of a sophisticated listening system.
