Compared with the obvious alternative at this price point — a basic solid-state amp that may be “good enough” but less special — A$850 looks like a strong buy for this model in the current used market. Against your own comp set, it sits well below the A$935 25th percentile and far under the A$1,766 median, so this is priced like a bargain rather than a stretch.
That makes sense if you want a Feliks-style tube experience: these amps are prized for a spacious, smooth, highly engaging presentation that flatters good headphones without sounding sterile. In excellent condition, with no obvious caveats flagged, this looks like a worthwhile opportunity for someone who wants a serious tube headphone amp without paying the usual premium.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
