Feliks Audio Say….
Feliks Audio is a boutique manufacturer of hand-crafted tube amplifiers, with over 20 years of audio solutions development experience. All our products are in-house engineered, tuned and assembled at our site in Lubliniec (Poland). We create special and unique designs, blending together technology and tradition.
Originally, Feliks Audio focused mainly on custom made amplifiers tailored to client’s order. Over the time we have developed many innovative and sophisticated audio solutions. Thanks to that we have gained valuable knowledge and experience across broad range of applications. Our amplifiers, among them Espressivo, Elise and Euforia, have won many supporters across the world.
Our products offer a perfect blend of passion for honest sound, great attention to technical details and beautiful finish. We do follow design simplicity, minimizing the number of elements in projected signal path. Thanks to this approach we ensure that the sound produced by our devices is pure and true.
Euforia is Feliks Audio flagship headphone amplifier launched in 2017. This beautifully handcrafted OTL, built around two 6SN7 and two 6AS7G tubes, delivers amazing dynamism, sound stage and level of details never heard of before in tube amplifiers, at the same time giving the unmistakably tube sound signature. Euforia’s unique design allows for exceptional sound quality with a broad range of headphones, powerful enough to drive even demanding low impedance headphones (<32 ohm) including planar magnetics.
Cross-Feed is a revolutionary solution in the class of tube amplifiers that provides better control over the listening experience. This is a system that enables more natural channel separation and wider sound stage by moving a part of the lower frequency range to the opposite channel.
listening to a regular headphones amplifier places you “in the middle of the orchestra” – with certain instruments being heard strictly in the left ear while others only in the right one. Depending on the type of music, this can cause discomfort and “listening fatigue”.
That’s why we decided to implement user-switchable Cross-Feed function among selected products. Our Cross-Feed function gives you a possibility to try a more natural, less clinical–“front facing orchestra” experience – like in real life!
Euforia is built with two 6N13S(also accepts 6080) power tubes and two driver 6SN7 tubes. Power supply is based on a custom made stabilized toroidal transformer with electronic ripple suppression. The amplifier is equipped with automatic bias circuit; therefore no re-tuning is required after changing tubes.
