  • Kevin is in LOVE with his Feliks Euforia EVO

    The Feliks Audio Euforia EVO proves that output-transformer-less is so much more. Kevin explains OTL design and what makes the Poland-made Euforia EVO a totally bad-ass, top-end headphone amp.

Feliks Audio Euforia EVO Headphone Amplifier

Feliks Audio's OTL flagship just got even better with an all-new faceplate, top-of-the-line internals, and XLR output.

The new Euforia EVO uses all of the upgraded internals from the 20th Anniversary Euforia, and has a stunning new faceplate design with XLR output. Easily drive headphones from 32 to 600 ohms, including planar magnetics.  

Euforia EVO Upgrades

  • 100% pure single crystal copper wiring
  • Mundorf capacitors
  • Dale and Caddock resistors
  • Improved gold-plated sockets, tighter and more robust
  • A new shielded and ultra-low-noise transformer
  • Improved cable shielding

About Euforia EVO

Euforia is Feliks Audio's flagship 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 that 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.

Crossfeed Feature

Crossfeed is a revolutionary solution in the class of tube amplifiers that provides better control over the listening experience. This is a system that enables more natural channel separation and wider soundstage by moving a part of the lower frequency range to the opposite channel. Listening to a regular headphone amplifier places you “in the middle of the orchestra” – with certain instruments being heard strictly in the left ear while others only in the right one. Depending on the type of music, this can cause discomfort and listener fatigue. That`s why we decided to implement user-switchable cross-feed function among selected products. This lets you try a more natural, less clinical–“front-facing orchestra” experience – like in real life.
