Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Fezz Audio leverages its parent company, Toroidy.pl, a specialized transformer manufacturer, to create unique toroidal transformers specifically designed for their tube amplifiers, a departure from the more common E-I core designs.
- The brand often presents a sonic profile that balances traditional tube warmth with clarity, detail, and accurate frequency response, resulting in a sound that appeals to both tube enthusiasts and those seeking a more neutral presentation.
- Fezz Audio uses readily available and relatively inexpensive tubes such as EL34s, KT88s and 12AX7s while retaining great performance, making tube replacement affordable.
- They offer a range of customization options, such as different colors, Bluetooth connectivity, or home theater inputs, at an affordable price, allowing customers to tailor their amplifier to their specific needs and preferences.

Our take on the brand
Look inside the brand
Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
One of the key technological innovations that differs Fezz from other manufacturers is the usage of patented toroidal output transformers in our tube amplifiers. While most tube amplifier manufacturers rely on traditional EI-core transformers, we design and build our amplifiers around custom toroidal output transformers. This results in lower magnetic leakage, much improved bandwidth, and more precise bass control—qualities that are not easy to achieve with conventional designs.
Secondly, we strongly believe in balancing modern engineering with classic tube sound. Our amplifiers are meticulously tuned to retain the musical warmth and dynamics that tube enthusiasts love, while also delivering the clarity, stability, and efficiency demanded by today's high-end audio systems.
What's your approach to customer support?
We handle customer support through a dedicated network of authorized dealers and distributors, who are the first point of contact for our customers. However, we also encourage direct contact with us if a customer needs additional help or feels their issue requires further attention. Our team is always ready to support end users with technical advice, service coordination, or general questions.
What are your favorite tracks for showcasing the strength of your products?
Great question! Music is the key to everything we do.
Melody Gardot – Worrisome Heart
Stacey Kent & Jim Tomlinson – So Nice
John Lee Hooker – Susie (feat. Johnny Winter)
Katie Melua – Piece by Piece
These tracks aren't just technical tests—they're emotionally engaging, which is exactly what we want our amplifiers to bring out in every listening session.
What other products pair best with yours?
We especially love pairing our amplifiers with Klipsch, and next is the Polish brand Pylon.

- Natural, fluid, musical sound with a bit of warmth, superb soundstage, and resolution
- Exceptional detail for the price category and low distortion
- Great build quality and a pleasing aesthetic, being hand-built
- Also works as a preamplifier for stereo setups
Product Considerations
- Not designed for planar magnetic headphones or for low impedance headphones
- May sound brighter, with lower bass quantity and precision, with low impedance headphones
- Tubes are consumables and will burn out after a couple thousand hours of use
- The power switch is located on the back, which some may find inconvenient
Comparisons (according to reviewers)
- Vs SPL Audio Phonitor 2 amp—Echo 2 provides a more refined experience
- Vs Hagerman Tuba—Echo 2 has better driving power and clarity for high impedance headphones
- Vs Audio-gd Master 19—Echo 2 has a more natural tonality and deeper soundstage for high impedance headphones
- Vs Violectric HPA V340—Echo 2 has a more magical musicality and a smoother presentation for high impedance headphones
- Vs Burson Soloist 3X Performance—Echo MKII leans towards a slightly more relaxed sound, while Soloist leans into a more forward aggressive one, and the Soloist has stronger treble extension
Takeaway: The Feliks Audio Echo 2/MKII is a great tube amplifier for those who appreciate engaging and emotionally rich listening sessions, especially with high-impedance dynamic headphones. This hand-built amplifier offers a unique musicality and adds warmth and depth to music.
