Feliks Audio is a Polish family company that has built vacuum-tube amplifiers in Lubliniec since 1999, when electronics engineer Henryk Feliks turned a hobby into a business. The first model to find a wide audience was the Espressivo headphone amplifier. Headphone amplifiers, including output-transformerless designs, are its main line, and the company now ships to listeners worldwide, including collaborations with ZMF Headphones.
Range & what it's known for
The entry Echo Classic sells at EUR 749 and the Echo Vibe with CNC-engraved wooden panels at EUR 999, both OTL designs on 6N1P and 6N6P valves. Above them sit the Elise and Euforia series, then the Envy, a 300B single-ended headphone amplifier. The Arioso 300B drives loudspeakers. The EOS, shown as a prototype at HIGH END Vienna 2026 with a display and remote control, is the first model to drive headphones, IEMs and loudspeakers from one chassis, using two 300B output valves with CV181 or 6SN7 drivers and doubling as a preamplifier. Point-to-point wiring without circuit boards, custom-wound transformers, NOS valves and parts from Mundorf, Nichicon, ClarityCap, Dale and Caddock are house practice. The EOS is rated at 5W for headphones and 4W for speakers at 1% THD, with 6.3mm and 4-pin XLR outputs.
Who owns it and where it's made
The firm remains family-owned. Henryk Feliks was joined in 2014 by his sons Lukasz, Piotr and Michal, who expanded sales abroad. A team of about ten people designs, assembles and tests every unit in Lubliniec, a town in the Silesian region of southern Poland.
The lineup in this catalog
Headphone amplifiers across several items, priced roughly from USD 500 to over USD 10,000, with the EOS at the top.
Who it's for
Headphone listeners, including IEM users with sensitive earphones, who want a hand-built tube amplifier from a family workshop. The Echo is a sensible first step with high-impedance headphones, Euforia and Elise are the mid-range upgrades, and the Envy and EOS serve owners of demanding flagship headphones who may also want to drive speakers.
