EVOlution never ends

The Euforia is Feliks Audio’s flagship OTL headphone amplifier launched in 2017. This beautifully handcrafted OTL, built around two 6SN7 and two 6AS7G tubes, delivers amazing dynamism, sound stage and level of details never heard of before in tube amplifiers, at the same time giving the unmistakably tube sound signature.

Euforia's unique design allows for exceptional sound quality with a broad range of headphones, powerful enough to drive even demanding low impedance headphones (<32 ohm) including planar magnetics.
