Founded in 2015 by the Lachowski family—father Lech and sons Maciej and Tomasz—Fezz Audio emerged as a sister company to the established transformer manufacturer Toroidy, which has been producing high-quality toroidal transformers since 1992. Based in the beautiful Podlasie region of north-eastern Poland at Kolonia Koplany 1E, 16-061 Juchnowiec Kościelny near Bialystok, Fezz Audio has revolutionized vacuum tube amplifier design through their pioneering use of toroidal transformers, becoming the first company in the world to incorporate toroidal output transformers in single-ended amplifiers. Under CEO Maciej Lachowski's leadership, who combines his electrical engineering education from Bialystok University of Technology with a passion for music and sound, the company has grown to employ 30 people while maintaining their family business philosophy of creating amplifiers that deliver 'unforgettable emotions and a unique experience.' Drawing from over 30 years of transformer manufacturing expertise at parent company Toroidy, Fezz Audio specializes in both single-ended and push-pull tube amplifier configurations featuring premium tubes including KT88, EL34, and 300B models, with their diverse product lineup spanning the affordable Ovo series to the flagship Lybra 300B parallel single-ended amplifier priced at $5,995. The company's innovative approach combines traditional tube warmth with modern toroidal transformer technology, resulting in amplifiers characterized by exceptional dynamics, wide tonal range, and what audiophiles describe as 'tube-like magic' with enhanced efficiency and reliability. Notable products include the award-winning Silver Luna Prestige integrated amplifier with Russian EL34 pentodes delivering 35Wpc, the efficient Titania stereo amplifier at $3,995, the single-ended Mira Ceti 300B model, and the recently launched Evolution Line that earned the prestigious Red Dot Design Award 2023 for innovative industrial design. Operating with the mission 'Made of Music,' Fezz Audio has established itself as a respected Polish audio manufacturer in the global high-end market through distributors including Audio46, Alma Music and Audio, Bluebird Music, and international partnerships, while maintaining their commitment to reliability, excellent sound quality, modern design, and their core belief that music should be experienced 'in a full spectrum' through products that bring people together and showcase the complete range of musical emotions.
