Feliks Audio launches EOS headphone and speaker amplifier

Feliks Audio has introduced EOS, a tube amplifier for headphones and loudspeakers. The Feliks Audio EOS uses two 300B power tubes and is scheduled for availability at the end of September 2026. These are paired with two CV181/6SN7 driver tubes.

Headphone output is rated at 5 W at 1% total harmonic distortion, rising to a maximum of 8 W at 5% THD. Loudspeaker output is rated at 4 W at 1% THD and a maximum of 6 W at 5% THD. The amplifier supports headphones and in-ear monitors with impedances down to 10 ohms.

Input connections comprise two pairs of RCA sockets and one balanced pair of XLR sockets. Preamplifier outputs are provided on one pair of RCA sockets and one balanced pair of XLR sockets. Headphones connect via 6.3 mm and four-pin XLR outputs, and there are dedicated loudspeaker outputs. The amplifier allows switching between headphones and loudspeakers while both remain connected.

The front display shows input, output and gain settings, along with a VU meter. Its diagnostic display provides operating voltages, internal temperature and tube-health information. A diagnostic check can be started from the front panel. The included remote control operates motorised volume adjustment, input switching and gain adjustment.

EOS measures 47 × 47 × 29.5 cm and weighs 26 kg. Finish options are Oak and American Walnut. There are 115 V and 230 V AC versions, both operating at 50/60 Hz.
