Compared with dropping US$2,400 on a brand-new tube amp, this is a fair-to-good used buy rather than a steal. New Euforia Evo pricing sits around US$2,990 to US$3,000, while recent used asking and sold examples cluster roughly from US$2,000 to US$2,200, so US$2,399 is a touch above the middle of the pack and a bit ambitious unless the unit is exceptionally complete and clean.
What makes it worth chasing is that the Euforia Evo is a seriously respected OTL design: spacious, fluid, and very natural with high-impedance dynamics, yet still capable enough to keep many planars happy. If it’s been babied, includes the original tubes, packaging, and proof of recent purchase, that adds real value here; if not, the price starts to feel merely fair.

Feliks Audio traces its roots to Poland, where electronics engineer and audio enthusiast Henryk Feliks began designing amplifiers over 40 years ago as a passionate hobby. Around 20 years ago, he turned this pursuit commercial, selling custom-made units initially within Poland. In 2014, the second generation—sons Łukasz, Piotr, and Michał—joined the family business, elevating it into a global operation based in Lubliniec. Today, this tight-knit team of about 10 crafts products with over 25 years of accumulated expertise in tube amplification.
The brand specializes exclusively in handcrafted tube amplifiers, with a sharp focus on headphone applications. Their lineup includes output transformerless (OTL) designs like the accessible Echo, high-end models such as the Envy Susvara Edition, and even esoteric electrostatic amplifiers like the Bliss, which supports both modern and vintage headphones. Every piece is in-house engineered, tuned, and assembled, blending natural materials and unique topologies for purist performance, often doubling as preamps for active speakers.
Feliks Audio occupies a niche boutique position in the high-end hi-fi market, revered by headphone aficionados for its emotional, rewarding sonics that prioritize musicality over sterile precision. Distributed in over 20 countries through select channels, their four-figure pricing reflects premium, small-batch quality rather than mass-market volume, appealing to discerning buyers who value tradition-meets-innovation in tube-driven headphone amplification.
