    Feliks Audio Euforia Anniversary Edition

    Feliks Audio are famed tube amplifier manufacturers from Poland and their heritage makes an appearance in their flagship headphone amplifier, Euforia Anniversary Edition. Headfonia have detailed the advancements and the superlative improvements made to one of Head-Fi's most transparent sources, the original Euforia. [See Product Desc. For More] Stereophile's Herb Reichert writes that Euforia "allows recordings to feel more direct and unmolested" – high praise from one of the world's most experienced listeners. The same writer found its pairing with the HEDDphone by Heinz Electrodynamic Designs (HEDD) particularly enriching. You'll be able to see everything from Feliks Audio here and all our other DAC & amp options here.

    Feliks EliseFeliks Elise

    Feliks Elise

    Adding scale and stage to Feliks Audio's impressive Echo II is Elise. Tube character abounds but never enough to take away the life-like realism of actual music in this OTL amplifier in single-ended triode format, based on the 6SN7 driver stalwart. You'll struggle to dispute Elise's quality at portraying an orchestral piece of work, or its magic synergy with Audio-Technica, Sennheiser or ZMF Headphones. Give it one listen, or many. Rarely will a single piece of gear fit as many sources, genres or set-ups. [See Product Desc. For More] Its mids are liquid and forward, great to address any flaws still present in your flagship cans. Warm, natural and wholesome even harmonic sound dominates – a direct result of Elise's single-ended Class A topology. The holy grail of all bias schemes isn't undertaken lightly, and new current sources ensure Feliks Audio's classic single-ended triode amplifier runs stably fully biased at all output levels. This is a decidedly low-distortion affair in an inherently linear amplifier given high tube operating voltages and current. Transconductance increasing with bias current is optimal. And while tube imaging, emotiveness and liquidity is de facto, Elise always sounds natural and fully transparent. Indeed, despite its mid-range vivacity, a massive audio bandwidth is guaranteed given its output transformer-less OTL construction. Literally nothing separates you from your music. Pairs of 6SN7 and NOS 6N13S tubes power your headphones directly, without any chunk of iron in the signal path.  Elise champions frequency extension – the fast, deep bass and airy, open highs from the best OTL associations to perfect phase reproduction and respectable damping factor – therefore. Long tube operating lifespans come courtesy of improved thermal management and more efficient passive cooling driving up to 60 per cent lower operating temperatures in the incumbant, versus its predecessor. Really, it's never only about the parts, and Elise is further proof boasting a new tube cathode heater and power supply design derived from the flagship Euforia. Great design nous gives a premium, Polish-built amplifier the platform to perform quietly and transparently.  Whether you go up or down, you'll be served browsing the rest of Feliks Audio's offerings here, or all our other DAC & amp options here.

    Feliks Audio Euforia

    Feliks Audio are famed tube amplifier manufacturers from Poland and their heritage makes an appearance in their flagship headphone amplifier, Euforia. Based on the historic 6SN7 tube family, Euforia's transparency matches some of the best solid-state amplifiers on the current market. [See Product Desc.

    Feliks Audio EnvyFeliks Audio Envy

    Feliks Audio Envy

    For OTL tube manufacturers Feliks Audio, the route to the top of Head-Fi's hill ran contrarian with massive Lundahl output transformers – and still proved to be the Envy of everyone. A flagship powerhouse amplifier, its design centered around famed 300B tubes. While Echo II to Euforia had proven to be delicate, pure and low-powered affairs, there is nothing subtle about the construction of Envy. Feliks set out to build the ultimate tube amplifier pushing over 5 watts of Class A power into any normal load at clipping. Effortlessly able to drive Susvara – in fact lauded by Ear Fidelity as the best headphone amp they've heard HIFIMAN's flagship through – Envy is a true statement of ambition by these prolific Poles. Headfonia warn it'll be the Envy of you after electing it to their Recommended Buys list. And Headfonics call it an essential demo if you want to elevate any elite flagship headphone. [See Product Desc. For More] As you'd expect of a statement amplifier, Envy can have no weaknesses. Depending on output transformers for brute power, this Feliks flagship still retains all the purity that this brand has come to be defined by. It's a champion of frequency extension both up and down; chunks of iron in the signal path or not. Running in single-ended Class A to preserve the all-important even order harmonics triode enthusiasts crave from such topologies, Envy is inherently linear. Its high operating voltage and high bias means that its entire circuit operates stably with zero feedback. That's aided by the use of 300B tubes providing Feliks Audio access to square law and load-line characteristics to push distortion down from the drawing board. Triode plate impedance also means that any clipping is soft and graceful, veering from harshness. Running in the open loop doesn't stop Envy from producing enormous frequency extension up to 100Khz at -3dB. The preservation of high-frequency triode transparency is certainly no mean feat without the aid of negative feedback. Meanwhile, the finest coupling capacitors and its large Lundahl output transformers sees low frequencies plumb down to 8Hz – truly subterranean levels, for a tube amplifier of any sort. WATCH ALSO Timelapse: the painstaking hand-assembly of Envy This Feliks frequency extension pays off in truly flat phase reproduction in the audible human hearing range, for impactful bass and realistic portrayal of musical images. Dynamics are life-like and on par with the best solid-state amplifiers. Indeed, none of the resolution Feliks Audio has been associated with from its OTL work has been lost in Envy, bearing uber-revealing CV-181 drivers from Psvane. But users wanting to squeeze the final drops of detail have the opportunity to build this behemoth in its Performance Edition, featuring UPOCC point-to-point copper wiring, and upgraded 300B power tubes from Electro-Harmonix to Full Music for the ultimate signal path. Inside and outside, Envy is a prestige product that belongs in a reference Hi-Fi rack. Its balanced pre-amplifier outputs allow you to operate it just that way into a full-sized, stereo power amplifier, passing through the entire 6SN7-300B stage and out through the rear. Definitely place Envy somewhere prominent: you won't be able to tear yourself away from gazing upon its beautiful wood build, nor hearing this pinnacle, for long. Otherwise, seek Feliks Audio's other OTL builds if you're looking for a smaller footprint here, and our other amplifiers here.

    Feliks Echo IIFeliks Echo II

    Feliks Echo II

    The star of the entry level demands your attention. Feliks Audio's Echo II defies what you'd come to expect from a beginner tube amp, blurring the lines between solid-state energy and natural tube tonality. You'll want to test this out as your first amp for certain – pair this with a high-impedance headphone from Audio-Technica, Sennheiser or ZMF Headphones, and you're off to audio nirvana via the lively, energetic performance Echo II particularly excels at! [See Product Desc. For More] Coloured yet correct, there's still a tonal evenness throughout that means you can trust this is the way your music was meant to sound. Its ability to drive planar magnetic headphones has improved further, with increased power output offering more flexibility and synergy with such low-impedance transducers than ever before. The same is true of source selection, with three RCA inputs to choose from. Echo II's massive audio bandwidth is a plus at this price point and comes courtesy of an output transformer-less OTL construction. Affordability, it appears, is no excuse to compromise pure performance in Feliks Audio's books. With a pair of 6N6P and 6N1P tubes driving your headphones directly without a chunk of transformer iron in the signal path, there's literally nothing standing between you and your enjoyment of music. Here's a lesson of legacy technologies done right – already, the single-ended Class A nature of Echo II means you'll enjoy the audio gains from the holy grail of bias schemes, without paying an arm and a leg for warm, natural and wholesome even harmonic sound. You'll be able to see the explore what these traditional principles are capable of doing pushed to their maximum higher up Feliks Audio's line-up here, along with all our other DAC & amp options here.
