EUFORIA EVO

OTL Vacuum Tube Headphone Amplifier

 
 
Euforia EVO is Feliks Audio's flagship-grade headphone amplifier. This beautifully handcrafted OTL, built around two 6SN7 and two 6AS7G tubes, delivers amazing dynamism, soundstage, and detail rarely heard from tube amplifiers, while at the same time still producing an 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 most planar magnetics. Connect via the 6.3mm jack, or the 4-Pin XLR output.
 
It presents as smooth, neutral, and dynamic. Carefully crafted in Poland, UPOCC wiring, premium components, and a point to point design within ensure unrivalled neutrality and soundstage. 
 
Rarely found in the world of tube headphone amplifiers, Euforia EVO also features an innovative crossfeed circuit, enabling more natural speaker-like listening with your headphones. 
 
  • Unrivalled neutrality and soundstage
  • Incredibly detailed and dynamic presentation
  • Crossfeed circuit; a revolutionary solution in tube amplifiers
  • Virtually no background noise
  • Beautifully hand-crafted in Poland
  • Broad frequency: 8Hz–75kHz +/- 3dB
  • Premium driver tubes
  • Improved noise reduction circuit
  • High-end class power transformer
  • Preamp safety circuit
  • Gold-plated RCA inputs
  • 3-year warranty (6 months on vacuum tubes)
 
The System 
Euforia is built with two 6N13S (also accepts 6080) power tubes and two 6SN7 driver tubes. Its power supply is based on a custom made stabilized toroidal transformer with electronic ripple suppression. The amplifier is equipped with automatic bias circuit, therefore no re-tuning is required after changing tubes.
 
Crossfeed 
Crossfeed is a revolutionary solution in this class of tube amplifiers that provides better control over the listening experience. This system enables more natural channel separation and wider soundstage by moving a part of the lower frequency range to the opposite channel. A small switch beside the power socket activates the crossfeed circuit. 
 
Listening to a regular headphone amplifier can place 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 in Euforia EVO. This lets you try a more natural, less clinical experience — like listening to the orchestra in real life, or a set of stereo speakers in a room.
 
Euforia Evolved 
Euforia EVO features excellent internal 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
 
OTL 
'OTL' refers to a tube amplifier that is Output Transformerless. Euforia EVO offers a highly musical and detailed sound that is true to the tubes themselves by omitting output transformers, which can colour the sound. Feliks Audio has always followed design simplicity, minimizing the number of elements in projected signal path; thanks to this approach, we ensure that the sound produced by our devices is pure and true.
