About the Euforia EVO

Euforia is Feliks Audio’s flagship introduced in 2017. This beautifully handcrafted OTL amplifier, using two 6SN7 tubes and two 6AS7G tubes, delivers remarkable dynamics, soundstage and detail—while retaining that unmistakable tube signature.

Euforia’s unique design offers exceptional sound quality across a wide range of headphones and is powerful enough to drive demanding low-impedance headphones (<32 Ω), including planar magnetics.

Crossfeed feature

Crossfeed is a revolutionary solution in the tube-amp category, giving you more control over the listening experience. It creates a more natural channel separation and a wider image by feeding a portion of the lower frequency range into the opposite channel.

With a conventional headphone amplifier, you’re often “in the middle of the orchestra”—some instruments appear only on the left, others only on the right. Depending on the music, this can lead to discomfort and listener fatigue. That’s why Feliks Audio implemented a user-switchable Crossfeed function on selected products, allowing you to try a more natural, less clinical “front-of-orchestra” presentation—closer to real life.
