International Audio Holding, the globally renowned company behind the prolific brands Siltech and Crystal Cable, has its roots firmly in the landscape of Dutch engineering technology. The history of the two brands starts well over three decades ago in the little Dutch town of Elst, near WWII-famous Arnhem, with the establishment of Siltech
(Silver-Technology). When Edwin Rijnveld, electronic engineer by profession and music lover by heart, took over the company in the mid-nineties Siltech became the innovative brand as we now know it. Gabi Rijnveld, Edwin’s wife, joined the company and soon their shared love for music would lead to many groundbreaking designs. One of them would become a brand of its own; Crystal Cable.
