What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

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.

Our summary
Product Strengths
- More musically convincing, more detailed, more harmonious, more linear, and more transparent than any other similar EL34 design at any price.
- Piano music is most perfect and quick, with purity of tone and tambour with proper richness and speed.
- Silent with totally black backgrounds, micro and macro dynamics are unrestricted and natural.
- Reveals its glory quickly due to its transparency.
- Excellent fit and finish and it worked right out of the box.
Product Considerations
- Thick or lean sounding cables will make the 534 sound thick or lean, and it needs top-quality isolation and support.
- The reviewer recommends buying the 534 new as they haven't auditioned the original from the beginning of the century.
- The only major flaw is that it doesn't have 500 watts per channel, but a custom one can be ordered for a very high price.
Comparisons (according to reviewers)
- Vs E.A.R. 890: The 890 is more robust and powerful, but not more convincing if your speakers don't need the power.
- Vs Cary Audio Custom 300B: The 534 is vastly superior.
Takeaway: The E.A.R. 534 is a musically convincing and transparent amplifier that reveals nuances in music. It is easy to place, beautiful to look at, and can make vocals and piano sound exquisite.
