At US$800, this asking price is ambitious for a Feliks-Audio Espressivo Mk II, sitting well above the median used price of roughly US$692 and the 25th percentile of US$656 drawn from recent comps. While a separate listing for the original Espressivo-E cites a new price near US$349 and the Mk II has seen used sales around US$600–US$700, US$800 exceeds the typical range unless the unit is pristine, includes premium tubes, or has rare accessories.
The Mk II remains a respected OTL tube amp prized for its lush, dynamic sound and strong compatibility with high-impedance headphones (100–600Ω), delivering 400mW with low distortion (0.4% THD). Its hand-built Polish construction and warm, musical character make it a standout budget tube option. Only consider it at this price if the condition is exceptional, tubes are upgraded, and all original accessories are included; otherwise, wait for a listing closer to US$650–US$700.

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.
