What reviewers are saying
We read all the reviews. Here's what reviewers feel most strongly about:
- Lab 12 emphasizes a "fine symmetry design," which focuses on technical symmetry and parts matching between the two channels, leading to sharper image focus and superior transparency.
- The brand's designs are focused on optimizing the listening experience, prioritizing a natural and involving sound that avoids analytical or clinical qualities.
- Lab 12 uses a "separate rails, separate grounds" (SRSG) technology to keep high current circuits independent from signal circuits to minimize noise and maintain signal purity.
- They implement fully tube-based designs in many products while keeping the build quality high and the pricing relatively accessible within the high-end audio market.
Our favorite reviewer quotes:
- "The epitome of tubey-ness, the Mighty is a wonderful blend of new and old, providing a massive soundfield, well controlled bass, and a luscious top end. This is one you can listen to all day." (https://www.tonepublications.com/distilled/lab-12-mighty-power-amplifier)
- "The Suara's sonic signature is nothing short of mesmerising. Delivering 50W per channel in pure Class A topology, this amplifier presents music with a level of naturalness and authority that's rarely encountered." (https://www.theaudiotailor.com.au/blogs/reviews/lab-12-suara-power-amplifier-review-a-masterclass-in-pure-class-a-amplification)
- "The TRUE's ability to maintain micro and macro details is nothing short of extraordinary. It handles dynamic shifts with remarkable grace, from the subtlest pianissimo to the most thunderous crescendos." (https://www.theaudiotailor.com.au/blogs/reviews/lab-12-true-input-selector-review-the-purists-path-to-audio-excellence)
- "The no-feedback design philosophy results in a presentation that's both pure and engaging. Bass notes possess authority without overwhelming, midrange exhibits natural warmth, and high frequencies sparkle with crystalline clarity."

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.
