Freshly arrived in our region, Feliks Audio is one of those gems that we have been following closely. A Polish firm, as discreet as it is serious, whose quality creations have been able to put all listeners in tune. A brand that has never had the chance to feature in our columns… until now, with the arrival of the latest model: the aptly named Euforia Evo, billed as the benchmark for home headphone amps.<\/strong><\/p>\n\n\n\n

<\/p>\n\n\n\n

Founded in 1999 in Lubliniec, Poland, Feliks Audio is, as usual, the work of an enthusiast. That of Lukasz Feliks, eponymous creator, passionate about sound and more specifically amplification – with tubes, moreover. A hobby that first served his designs, then those of his friends, quickly followed by enthusiasts, all as seduced as they were impressed by his high-fidelity headphone amps.

Unique creations with rustic charm, combining cutting-edge technique and age-old technology, for a result worthy of the greatest houses. A combination that will hit the mark, with Feliks Audio first gaining critical acclaim before acquiring a real reputation among the audiophile community.

This was followed by almost organic growth, fuelled by constant demand, supported by an ever more voracious market, perpetually in search of the best amplifier\/headphone system (your editor’s guilty pleasure). This success enabled the timid workshop of the early days to achieve the status of a manufacturer, with Lukasz and his team making it a point of honour to maintain production lines in Poland, where the company is based.

But it was at the end of 2017 that the team achieved recognition with the release of the first Euforia. A tube headphone amplifier, successor to the Espressivo and Elise, which propelled Feliks to the forefront and inscribed the name of this company in the pantheon of major brands. In 2019, the brand even released a 20th anniversary version, soberly titled Euforia Anniversary, followed a few months later by the Envy \u2013 the epitome of the range \u2013 but it wasn’t until 2022 that we finally saw a true successor: the Euforia Evo.<\/p>\n\n\n\n

Presentation<\/strong><\/p>\n\n\n\n

A clear aesthetic success, with the Evo Feliks Audio treats us to an OTL (no output transformer) amplifier in a neoclassical style, retaining the brand’s signature codes while adding a touch of modernity.

Updated, the front panel has become more refined, swapping the antique central potentiometer for a much more imposing controller, now nestled on the right of the front panel. A majestic cylinder, with a logo to boot, offering a much better grip for precise volume control. In the mirror, on the left insert, we find the traditional 6.35 mm jack output, this time accompanied by a balanced output, in 4-pin XLR format, which will delight demanding headphone owners.

At the back, the Euforia is very classic: an RCA line input, coupled with a line output also in RCA format, supplemented by an IEC C14 power port, almost eclipsing the tiny cross-feed switch discreetly housed on the far left of the backplate. A traditional design, therefore, supported by a two-part construction. The amp consists of a solid aluminium base with the amplifier tubes on the first half, and on the second half a solid rectangular block concealing the PCB.

Because it is under its thick layer of aluminium that the Euforia Evo hides its finest assets. An internal circuit combining the best of analogue: ClarityCap capacitors with CopperConnect, Neotech UP-OCC internal wiring sheathed in Teflon and point-to-point soldering, entirely hand-made by Lukasz and his team.

Finally, there is the highlight of the system: the tubes. Overlooking the whole, the quartet is made up of two power tubes – 6N13S Russian lamps known as New Old Stock – and two PsVane CV131 MK2 Gold preamplifier tubes with, as their name suggests, a gold base for the most beautiful effect.

The little something extra? An assembly with almost no visible screws, from which no screws are visible, reinforcing the sense of prestige that our amp exudes.<\/p>\n\n\n\n

The set-up<\/strong><\/p>\n\n\n\n

Reduced to its simplest form, the Euforia Evo’s connectivity makes it particularly easy to install. Supplied with the bare minimum – a power cable and its tubes, the protective grille being sold separately – all you have to do is install the tubes according to the diagram provided, connect it to a source via its line input, then connect the power supply and start it up.

As usual, it will take a long time to start up, as the cathodes need to warm up, but once it’s done, all that’s left is to connect the headphones. Note that it will even be possible to connect a power amplifier to it, via the pre-amplified line output! A feature that we obviously took advantage of.<\/p>\n\n\n\n

<\/p>\n\n\n\n

The sound<\/strong><\/p>\n\n\n\n

Wearing our venerable Sennheiser HD800S and complemented by an Auralic DAC, Feliks’ little block impresses, surpassing our traditional Cayin HA-1A MK2 and even approaching the Studio 6 from ALO Audio, our master standard.

The Euforia gracefully distils the most subtle nuances, while retaining that very special tube tessitura, a perfect balance of rigour and warmth. Taut bass, chiselled treble, deep mids, all enhanced by a wide soundstage. This is even more striking in stereo where, in addition to the clear gain in power, there is a better definition of the voices and a more pronounced staging of the planes, with each effect suddenly seeming closer, almost palpable.

This blend of elegance and refinement is emphasised by our Sennheiser, which is particularly at ease with our amp. Accurate timbres, open soundstage, powerful impact, nothing is lacking, and whether it’s the polyphonic electro of Infected Mushroom or the chant of Stacey Kent, the combo draws us in, never letting us go.

Melodious but never syrupy, powerful without being aggressive, our amp liberates the voices, makes the strings vibrate and, note after note, breaks down the wall of doubt. A feat that is confirmed the more you listen to it, the synergy of the hits combined with the topology of the circuit delivering an excellent result at any volume level.

But more than the power, it is the acutance of the rendering that is truly captivating, often blurring the line between tubes and transistors, betrayed only by its relative weakness on our orthodynamic headphones.

Because yes, while it proves brilliant, even dazzling, on our high-impedance headphones – Sennheiser and Focal in particular – the Euforia Evo is a little less at ease on our planar models. A real challenge at this level!

And even if the subrogation of the Auralic DAC by a Chord Hugo 2 reduces the pitfall, it is difficult here to see it as a replacement for our SAEQ Audio PDA-1B, which is much more at home on Audeze and Meze. Fortunately, on our Celestee, the Evo quickly regains its splendour, once again placing the bell tower at the centre of the village.

Finally, for the more curious, Feliks also offers a cross-feed function, simulating the natural crosstalk of a traditional hi-fi system, on headphones. Usually superfluous but here really convincing, it widens the soundstage without blurring the message, for a more natural result, on almost all the headphones tested.<\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/p>\n\n\n\n

Our conclusion<\/strong><\/p>\n\n\n\n

The Euforia Evo is as elegant as it is competent, delivering a top-flight performance once it has been warmed up, once the right headphones are connected. More complete, more powerful and ever more efficient, it almost makes you forget its price, the only real drawback. A top-of-the-range headphone amplifier that deserves to be on the shortlist of any good audiophile, completed by a solid living room DAC and high-impedance headphones for a successful trio.<\/p>\n\n\n\n
