ENGINEERED FOR EVERYONE

History of Black Ice Audio/Jolida INC.

First a little background on how we ended up in the Audio Business.

In 1984, Jolida was contracted to design a series of large transformers for an industrial customer with the main criteria being low noise over a wide signal bandwidth. We realized that if the size of the transformer was reduced, it would be amazing in a tube amplifier. The transformer is the heart of a tube amplifier and unquestionably the most important component.

At that time the median price of a tube power amplifier was $3,600 and we saw an opportunity to build reference-level audio gear at prices that were obtainable by everyone. Since 1997, the Black Ice Audio has won Design and Innovation Awards from the CEA, product of the year awards, the Oasis award, and has products in Audio Review’s Hall of Fame (these are consumer appreciation awards).  Additionally, the company has garnered numerous positive worldwide reviews, even one from Time Magazine for our audio components.
