ACHILLES ULTIMA
- Positioning: A low-power tube amplifier designed for small rooms and high sensitivity speakers.

- Description: Features a built-in surveillance circuit and multi-input design including Bluetooth v5.0, offering comprehensive functionality in one unit. Compared to the other products, its blend of connectivity, tube monitoring, and moderate power output provides an all-in-one solution with advanced features.
APOLLON ULTIMA
- Positioning: A high-power monoblock amplifier engineered to drive power-hungry loudspeakers in larger spaces.

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.
