Gaetan Byk, who continues the journey with unique audio designs and one-of-a-kind projects

Paris, France July 20, 2021 – Gaetan Byk has announced that he has purchased Amadeus and is now the principal and majority shareholder in charge of the French designer and manufacturer of high-end audio equipment based in Paris, France. Michel Deluc, co-creator of the original Amadeus brand with Bernard Byk 30-years ago, has created many of the Company’s unique speaker designs and remains at Amadeus to lead specific design and manufacturing projects.

“For many years, my mission has been to find a space for Amadeus, a unique place where technological innovations with arts and crafts, combine and complement each other,”states Gaetan Byk, Owner and CEO of Amadeus. “I think we need to go where our main competitors cannot, do not know how to, or do not want to go!”

“Designing tailor-made solutions, responding to existing architectural, acoustic, and technical constraints have been our areas of expression for a long time. Over the past few years, some rather out-of-the-norm products were born this way,” continues Gaetan Byk.

Over the past 10-years, Gaetan Byk has guided the company and its products to new heights. Many unique products were created including the hi-fi Philharmoniareference monitor created with world-renowned architect Jean Nouvel for the Philharmonie de Paris concert hall recording studios; the stone-clad speakers made for the Panthéon; the unique speakers designed for iconic Krug Champagne House made of COR-TEN steel – cut and then laser welded – and today, the nearly 40-meter-long bespoke sound ramp designed for the Festival d’Avignon, the largest performing arts theater festival in the world.

Amadeus also equipped major venues (and festivals) all over the world, over the past years, including Asia Culture Center (South Korea), Beijing National Indoor Stadium (China), Festival d’Aix-en-Provence (France), Festival d’Avignon (France), Jarasum International Jazz Festival (South Korea), National Museum of Natural History (France), Opéra National de Bordeaux (France), Opéra National de Lyon (France), Opéra National de Rennes (France), Paradise City (South Korea), Philharmonie de Paris (France), Rhyality Immersive Art Hall (Switzerland), Royal Conservatory of The Hague (Netherlands), Seine Musicale (France), Panthéon (France), Théâtre National de Bretagne (France), Théâtre National de Marseille (France), Théâtre National de Toulouse (France), among many others…

Collaborating with IRCAM and several other key French institutions, Amadeus also figures among the pioneers of spatial sound for the live field. “The success of the HOLOPHONIX project, a sound processor that already equips some of the most prestigious musical, theatrical or international museum institutions, confirms our views in this direction,” adds Gaetan Byk.

The HOLOPHONIX immersive sound processor with its extensive unique, and powerful control software has been adopted by worldwide venues including the Théâtre National de Chaillot, La Scala, La Comédie Française, and many others.

Gaetan Byk explains the combination of business and creative design the company offers, Our approach is rather transversal and our technical knowledge within the company is very complementary. We mainly work in the electro-acoustic industry, namely the production of loudspeakers for live entertainment applications and high-end hi-fi – through the Philharmonia brand. We also deal with, on purely acoustic issues, the world of the recording studio, for many famous artists, producers, arrangers, and commercial studios. These departments have been, and continue to be, managed by Michel Deluc.”

“Finally, the development of the HOLOPHONIX brand, based around spatial and immersive sound, led us to new areas and markets,”states Gaetan Byk. “I think there will always be a place for innovative and unique products, as well as creative solutions that are designed, developed, and manufactured-on-demand.”

As Amadeus moves into the future with new projects, challenges, and creative solutions, Gaetan Byk offers his vision, “My goal is to remain, as far as possible, the majority shareholder of the Amadeus company structure to preserve our DNA and above all not enter into a logic of unbridled growth. My wish is to do better, not more.”
