Introducing Feliks Audio Euforia

The Feliks Audio Euforia is a beautifully crafted, hand-built tube headphone amplifier that exemplifies the brand’s commitment to exceptional craftsmanship. From the moment you lay eyes on it, you’ll notice the attention to detail and premium build quality. The amplifier’s elegant wooden housing not only provides acoustic benefits but also adds a touch of vintage charm to any audio setup.

Features and Specifications

Tube Configuration

The Feliks Audio Euforia features an alluring and potent tube configuration that includes a 6N30P triode power tube, a 6N6P double triode driver tube, and a pair of 6N1P double triode tubes. This thoughtfully curated combination delivers an exceptional blend of warmth, clarity, and detail, guaranteeing a truly enchanting audio experience.

Output Power

The Euforia boasts an output power of 250mW, providing ample power to drive high-impedance headphones with ease. This power output ensures that even the most demanding headphones can be driven effortlessly, delivering a lively and dynamic sound signature.

Audiophile-Grade Components

Feliks Audio leaves no room for compromise when it comes to selecting components. The Euforia is equipped with top-tier capacitors, resistors, and transformers, all handpicked to ensure minimal distortion and maximum fidelity, making it a perfect choice for discerning audiophiles seeking the ultimate sonic experience.

Audio Connections

For the best connectivity and audio quality, all Euforia inputs and outputs are gold-plated. One RCA input and one RCA pre-amp line out are located on the amp’s back. The power switch and the Cross-Feed switch (I’ll explain shortly) are both located on the back. A 14-inch headphone output and sizable rotary volume control are located on the front panel.


Upon plugging in your headphones and pressing the power button, the Euforia comes to life, unleashing a musical experience like no other. From the first notes, it becomes evident that the Euforia offers a spacious and transparent soundstage, immersing listeners in layers of sound with remarkable instrument separation.

The magical essence of tube amplification is fully realized with the Euforia. The warm, rich harmonics and delicate tonal nuances produced by this amplifier breathe new life into your favourite tracks, revealing details you might have missed with other amplifiers. Whether it’s jazz, classical, rock, or any other genre, the Feliks Audio Euforia gracefully handles all, elevating your listening sessions to an unforgettable level.

Euforia Tubes

The Euforia has a total of four tubes. 2 power tubes and 2 driver tubes. Depending on your budget, Feliks Audio offers three options for the driver tubes when you purchase a Euforia. PsVane CV-181 Mk2 “Gold” is the most expensive model, followed by PsVane CV-181 Mk2 “Silver” and PsVane 6SN7. Feliks Audio will give you two 6N13S (NOS) power tubes. You might as well splash out on the PsVane CV-181 Mk2 “Gold” since the price difference between the least expensive and most expensive option is only €200 (roughly $227 in March 2019).

However, if you want to save money, you can use your own tubes, so that route might be the best choice. The tubes that work with the Euforia are listed below:

  • Driver tubes: 6N8S, CV181, ECC32, 5692, 6F8G
  • Power tubes: 6080, 5998, 6N5P, 6N5S, ECC230, 7236, CV2523

Since the Euforia has an automatic bias circuit, tuning is not necessary when changing tubes.

It’s important to keep in mind that these amps run hot, with the tubes reaching as high as 150°C if you’ve never used one before. Do not attempt to handle the tubes for at least 20 minutes after powering down because it takes the tubes about 15 minutes to fully warm up before cooling down again. Additionally, place the Euforia in a well-ventilated area to prevent overheating.

The Euforia has a run-in period of between 30 and 50 hours before the amp achieves optimal audio quality, according to Feliks Audio’s user manual.

Cross-Feed Technology

Feliks Audio Cross-Feed is one of the Euforia’s more intriguing features. The sound stage is wider and more realistic thanks to this technology. The Euforia blends frequencies to create a more “forward-facing” sound stage instead of a rigid left/right separation. Comparable to finding the ideal speaker position where the left and right speakers naturally blend together to create the impression that the sound is coming from all directions. In the past, it was challenging to accomplish this with headphones, with the exception of Focal’s pricey, high-end audiophile models.

Any pair of headphones can now take advantage of this cutting-edge technology thanks to Feliks Audio’s success in creating this effect within the Euforia’s electronics. Even better, a switch is offered so you can choose whether to use Cross-Feed while listening to audio.


Everyone finds true love at this point. I have not heard anyone criticize the sound of the Euforia; it is simply sublime. The tonality is balanced and clear, probably the best in its price range category. In fact, it is probably superior to tube amps that cost two or even three times as much. It’s difficult to say that the Euforia produces a “typical tube sound” because it both does and doesn’t at the same time because the sound is so warm and smooth. It definitely belongs to a different class! You quickly understand why Focal suggests using a Euforia with their headphones.

The Euforia’s low-end response is flat and accurate. The tuning has not been altered in any way by Feliks Audio. The sound you receive is incredibly accurate, which you may or may not like. The Euforia’s low-end is great if you prefer a pure sound, and if you’d prefer more bass, you can adjust it with some EQ if you like. Since I value a true, flat sound, the Euforia is ideal for me.

The midrange’s clarity and dynamics are exceptional, especially when used with a set of Focal headphones. Vocals don’t sit as proud or upfront as some may prefer, but this isn’t in any way a flaw in the sound. I would definitely suggest giving the Euforia a listen if you prefer a mid-range with a more forward sound because you may be pleasantly surprised by its distinctive sound.

The Euforia shines brightest in the treble frequencies. The clear detail and tone produce an engaging and thrilling listening experience that is comfortable and easy on the ears.

The noise is the last. Tubes are frequently problematic, but not with the Euforia. This amplifier is extremely quiet. The internal circuitry has been superbly designed by Feliks Audio to keep noise at or below zero.
