The Gateway to Glow. Handcrafted Polish Soul for Your High-Impedance Classics.
There is a specific kind of magic that happens when you plug a high-impedance headphone into a proper OTL (Output Transformerless) tube amplifier. The Feliks Audio Echo Classic is the purest expression of that magic. Handcrafted in Lublin, Poland, this isn't a mass-produced piece of desk kit; it is a specialised instrument designed to make legendary headphones sing. By removing the output transformer from the signal path, Feliks Audio has cleared away the "veil," leaving you with a sound that is incredibly open, harmonically rich, and emotionally resonant. The Echo Classic represents the most honest entry point into the world of high-end European tube audio, stripping away the frills to focus entirely on the "glow."
The Heart of the Glow: 6N1P and 6N6P Tubes
The soul of the Echo Classic lies in its carefully selected glass. It utilizes a pair of 6N1P driver tubes to handle the delicate input signal and a pair of 6N6P power tubes to deliver the muscle. These aren't just off-the-shelf components; Feliks Audio uses high-quality NOS (New Old Stock) variants to ensure a lower noise floor and better longevity. Because the Echo Classic is an OTL design, these tubes are connected more directly to your headphones, allowing their unique harmonic character to color the sound in a way that feels natural and romantic rather than artificial.
Minimalist Polish Craftsmanship
Every Echo Classic is a testament to Feliks Audio’s "form follows function" philosophy. The chassis is constructed from high-grade steel, finished in a matte black that lets the orange glow of the tubes take centre stage. The real standout, however, is the real oak wood side panels. These aren't just stuck-on veneers; they are solid wood accents that give the amplifier a warm, heirloom-quality feel. It’s a design that looks just as good in a dedicated listening room as it does on a minimalist office desk, proving that professional-grade audio gear doesn't have to look like a piece of lab equipment.
