Feliks Audio Euforia 2018


To date, I’ve not had a tube amp in the house while here at Headfonics that could match this Euforia in raw quality output, nor that insane, uncolored tendency. Wow, is all I can say at this point.


Euforia proved such a great match particularly with Utopia that Focal's senior manager asked that Euforia be their reference tube amp for all future show exhibits.


A really good OTL design makes your transducers sound like they are direct-coupled to the music, and that is precisely what the Feliks Audio Euforia does to your headphones.


I do not know if it’s the top-of-the line tubes, point-to-point assembly with high-purity silver wiring, or the design of the amp itself, but the presentation is extremely neutral, clear and fast for a tube amplifier.


Euforia is Feliks Audio's flagship headphone amplifier launched in 2017. This beautifully handcrafted OTL, built around two CV-181 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.

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.
