Founded in Germany in 1975 by Hans M. Strassner, HMS Elektronik has spent five decades developing high-end audio products based on measurable engineering principles and uncompromising quality. From the very beginning, the brand has focused on one goal: preserving signal integrity, allowing music to be reproduced with maximum realism, dynamics and emotional impact.
Every HMS product is developed according to strict physical principles. Minimizing losses and protecting audio signals from external interference remain at the heart of the brand’s philosophy. This approach has led to highly acclaimed cable series such as Gran Finale 50 and Suprema MC², while ensuring that every product in the HMS portfolio delivers performance that exceeds expectations within its category.
Beyond cable technology, HMS has earned an international reputation through its expertise in power conditioning. The Energia Series combines advanced filtering technologies such as Ground Loop Suppression (GLS) and Direct Current Suppression (DCS) with carefully selected materials to reduce noise and contamination from the power supply. The result is a cleaner electrical foundation that allows audio systems to perform at their full potential.
Since 2024, HMS Elektronik has been part of Siltech Group, alongside renowned audio brands Siltech, Crystal Cable and Sphinx Audio Engineering. Today, all HMS products are handcrafted in the Netherlands, benefiting from shared expertise in metallurgy, cable manufacturing, research and product development while preserving the engineering philosophy that has defined HMS since 1975.
Combining a legacy of German engineering with Dutch craftsmanship and innovation, HMS continues to refine and expand its product portfolio for a new generation of music lovers. From signal transmission to power conditioning, every HMS product is designed to deliver one thing above all else: a direct and uncompromised connection to the music.
