Feliks Audio
Lubliniec, Silesian Voivodeship, Poland · founded 1999
Founder Henryk Feliks began building tube amplifiers as a hobby in the 1990s (for himself, friends and local music bands) before turning it into a business. The three-sons structure — Łukasz on sales, Piotr on production, Michał on design/marketing — is well documented in the founder-family Q&A. Legal entity is Feliks Audio Sp. z o.o. The brand is closely associated with OTL (output-transformerless) tube topology and is entirely independent / family-owned, with no conglomerate or parent-company ownership.
Feliks Audio is a Polish family-run boutique manufacturer of hand-crafted vacuum-tube headphone amplifiers, based in Lubliniec. Founded by electronics engineer Henryk Feliks, who built tube amplifiers as a hobby through the 1990s before formalizing the brand, the company is best known for its output-transformerless (OTL) tube headphone amps. Since 2014 Henryk’s three sons — Łukasz (sales), Piotr (production) and Michał (design/marketing) — have run the international business alongside him. Every unit is designed, assembled and tested by hand in Lubliniec. The lineup spans the entry Echo series up to the Euforia, the flagship Envy (including a dedicated Susvara Edition), and the summit-fi Bliss.
