G LAB Design Fidelity is an audio brand based in Poland which designs, develops and manufactures audio products, both professional and audiophile of highest possible quality and craftsmanship.

For us it’s all about the people. We bring  together enthusiasts from all walks of life. Audio, design, brand identity, engineering and business. All together we want to deliver you the finest audio products that not only will satisfy audio enthusiasts, but also design conscious customers. We are considered  “the niche of the niche”. All products are built with detailed and custom engineering  both mechanically and electronically. The process of developing a new product is not only hard work for us, but also  fun. We play with materials, with solutions and ideas.

Our heart is ELZAB, our production environment,  a factory that has been developing electronics and mechanics for over 40 years. The factory was started on 1st August 1969 in Zabrze, Poland. Great experience in manufacturing a wide variety of products, from first computers in the early 70’s through PC’s in the 80’s to modern cash registers, allows us to experiment with custom solutions and gives us professional support in engineering. Manufacturing our products in Poland allows us to control the quality every step of the way.

The idea of starting an audio brand was to deliver our customers products that have custom solutions, that are limited, and aren’t mainstream. Products that would have their own history. Products that were created with passion, fun and with respect to everybody who was involved in the entire process from the project on paper to the finished product.

BLOCK was a great challenge for me. It was the first project that was so advanced and fully functional at the same time. It brought me the opportunity to make a name for myself in the world of design. My dream was to see my product on the shelf and due to the Polish entrepreneurship of a few people my dream will come true.
