Should you call this $600 asking price a bargain, or is something missing? Yes, it’s a strong deal: the $600 price sits well below the 25th percentile of $656 from seven recent USD comps, and the median is $692, making this a clear bargain for a Feliks Audio Espressivo Mk2.
The Espressivo Mk2 is well-regarded for its OTL tube design that delivers fuller, better-layered sound than the original, stepping closer to the high-end Elise while staying affordable and fun to listen to. It pairs nicely with 32–600Ω headphones, offers 400mW output, and uses easy-to-find tubes like 6SN7 and 6N13S. At this price, even with unknown condition, it’s a compelling buying opportunity for anyone wanting genuine tube warmth without boutique pricing.

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.
