Who is Fezz Audio?
You know how Rome wasn't built in a day–neither was Fezz Audio.
While the company has been around since 2016, its parent company, Toroidy, has been producing power supplies for over 30 years, and they sit at the center of Fezz's story.
You see, Toroidy had three patents in the field of toroidal transformer design and production, and an opportunity to use this unique technology in high-end vacuum tube amplifiers. In 2016, Fezz Audio was born to seize that opportunity.
Since the day of inception, Fezz Audio has been making high-end components for audiophiles and music lovers alike in north-eastern Poland. Backed by Toroidy's technology, they set the bar high as the first company in the world to feature toroidal output transformers in their single-ended amplifiers, preserving their unique character while optimally coupling limited power output to loudspeakers.
Today, Fezz Audio is represented by distributors across Europe, Asia, Africa, and North America. Their product catalog consists of high-end tube amplifiers, DACs, power amplifiers, preamplifiers, and phono-stage solutions. Their mission? To deliver emotional, musical experiences that let listeners feel the full spectrum of sound.

Proprietary Toroidal Output Transformers
Fezz Audio single-ended amps are the first in the world to feature toroidal output transformers with three patents in the field of toroidal transformer design and production. Toroidy, Fezz Audio's sister company, specifically designs toroidal power and output transformers for select Fezz Audio amplifiers.

Why Toroidal Output Transformers?
In headphone amplifiers, clean power delivery is everything. Headphones are incredibly sensitive to noise, voltage fluctuations, and interference. Instead of the traditional rectangular core design most transformers use, toroidal transformers are wound around a donut-shaped core. This seemingly simple design change creates several great advantages: Lower electromagnetic interference (EMI), reduced mechanical vibration, better regulation, and higher efficiency.
Output transformers play a significant role in shaping the sound quality of your amplifier, and toroidal output transformers in particular lend unique sonic characteristics that other output transformers do not. With far lower flux leakage and radiated energy than standard transformers, toroidal power transformers ensure the amp's sensitive circuitry doesn't pick up any additional noise from the power supply. The result is extended bandwidth, a flat frequency response, and low distortion.
Craftsmanship
When it comes to hi-fi components, you typically get one of two things: An overly flashy, decked-out-to-the-nines component with all the bells and whistles or a simple, minimalist component with just the necessities. While I'm a big fan of the flashy audiophile excess, the simplistic nature of Fezz Audio components is a breath of fresh air in the hi-fi space.
Fezz Audio components sport a clean, minimalist design aesthetic–an outward representation of the sound quality and performance you get from a Fezz product. This modern design wouldn't be possible without the help of interdisciplinary design and strategic studio KABO & PYDO, who collaborated with Fezz Audio on its Evolution line. And that very line won KABO & PYDO the Red Dot 2023 award for its flawless workmanship, which is indicative of the product's smooth sound quality. Fezz Audio components are available in multiple color variants.
From a production standpoint, Fezz Audio is elite. Over 80% of Fezz Audio components are produced in-house at their facility in Kolonia Koplany, Poland. In-house production means more than just a stamp of approval to be considered 'Made in Poland.' This enables Fezz Audio to ensure every component meets stringent quality control testing, so you're never second-guessing the durability, reliability, and lifetime of your component.
Dragon Cables
Look, we say it time and time again–high-quality cables matter! When you're configuring your dream hi-fi audio system, you want every link in your signal chain to operate at the highest caliber. That's what Dragon Audio Cables promise–reliable performance and exceptional quality.
