EUFORIA EVO Headphone Amplifier and Preamp By Feliks Audio

The Feliks EUFORIA EVO is an unparalleled breakthrough in OTL technology, delivering unmatched audio performance and clarity. The component is designed as a headphone amplifier but it contains a pair of RCA output jacks, to serve as a brilliant tube linestage preamp into a speaker amplifier.

• Ideal for dynamic headphones and compatible with most planar models, delivering superior performance and sound quality.
• Features both XLR and RCA headphone outputs for versatile connectivity and optimal audio performance.
• Delivers a smooth, neutral, and dynamic sound with UPOCC wiring, high-quality components, and a point-to-point design for unmatched audio clarity and performance.
• Optional tube protection cage is available for added safety and durability.

Note: This headphone amplifier will only mate well with headphones that can operate with 280mW of power, which includes most headphones but not those that are considered difficult to drive.

“The driver tubes that came with the amp are a matched pair of PsVane CV-181 Mk2 “Gold” 6SN7 tubes and I must admit they really surprised me in a good way. I didn’t expect them to sound this detailed and dynamic and in combination with the 6AS7G. They just sound great and as a result I didn’t swap these out. The PsVane tubes are well constructed, and they look very nice too. “

“The Feliks Audio EUFORIA evo is an almost perfect riposte to the heady energy of the flagship Envy amplifier. This is an elegant OTL amplifier tailor-made to give you a smooth embracing tone and one that works wonderfully well with headphones such as the ZMF Headphones Atrium and the Focal Utopia 2022. I could listen to these enjoyable combos for hours without fatigue. “

“Euforia EVO delivers excellent performance that’s coupled with an elegant simplicity. While tube amps can seem intimidating – and adding in a fancy concept like the “output transformerless” design can add to that – but EVO’s plug and play nature and single volume knob operation makes it highly accessible. While the elegance and accessibility is great, what’s most important is the sound, and Euforia EVO is, without a doubt, one of the best sounding headphone amps we’ve ever heard.”
