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.
