Our story
The Spark
From Medical Precision to an Audiophile Necessity
The story of Haandrikman Audio Systems begins with a concrete, real-world problem. An audiophile with a top-tier system noticed that the sound quality of his setup would completely "collapse" at a fixed time almost every day—a direct result of the continuously increasing pollution on the mains power. He approached Ronald Haandrikman, whose company in the medical industry produces, among other things, power supply systems with isolation transformers for hospitals. The standards for these systems are extremely high.
​
For Ronald, an audio enthusiast himself with a background in developing high-end Class A and AB amplifiers, the interest was immediately piqued. A first prototype was built and submitted for evaluation to Wim van Kraanen, the highly respected owner of Analogue Audio Products in Nieuwegein. His reaction after the first listening session spoke volumes: "I finally got to hear a glimpse of the sound quality I was accustomed to 10 – 15 years ago." This was the unmistakable validation needed to take the project to the next level.

​The Philosophy
Addressing the Cause, Not the Symptom
​
Many audiophiles pay insufficient attention to the impact of ever-increasing mains pollution, even though this is precisely where significant gains can be made. This pollution does not manifest as a distinct hum or other audible noise but rather hides in the background. This results, for example, in haze, excessive sharpness, dynamic limitation, loss of musical detail, or a reduction of the image size. Usually, it's a combination of these unwanted effects. Haandrikman’s philosophy is that an audio system can only be as good as the quality of the mains voltage used to power de audio equipment. Instead of fighting symptoms, Haandrikman addresses the root cause by galvanically separating and purifying the power supply, with one crucial prerequisite: the dynamics must not be limited.
​
The Process
A Unique Collaboration
​
What followed was an intensive development process, driven by the expertise of two worlds. Wim van Kraanen was so impressed by the potential that he made his listening room, with his high-end reference system, available as a testing environment.
Ronald visited weekly with clever adjustments and new circuits. The collaboration was perfect: Ronald provided the technical know-how, and Wim offered his trained ears and honest, critical feedback. The prototype of the Sygnus X-1 was refined step-by-step and scaled up to a level that is rare even at the pinnacle of the audio world. This unique synergy between technician and listening expert ensured that the Sygnus X-1 is not only technically perfect but also provides the most musical solution in practice.

​​The Next Step
From Passion Project to Professionalism
​
What began as a passionate experiment quickly grew into a serious product. Initially, it was no more than a hobby that got out of hand, but when the first information about the Sygnus X-1 appeared online, demand arose organically from the audiophile community. The desire to experience the Sygnus X-1 in their own system rapidly increased.
​
This growth continued steadily until a tipping point: dealers and Hi-Fi stores showed serious interest. Demand for both the Sygnus X-1 and the Nexum HQ Power Cables, which had been developed in the meantime, kept increasing. This marked the moment to take the next step. To professionalize this growth and ensure quality, Haandrikman Audio Systems was officially founded in February 2024.

Mission
improve listening experience
​
Our mission is to fundamentally improve listening experience by eliminating the invisible enemies of sound: noise and pollution in the power and ground connections. We develop the most advanced Total Power Management Units and precision cabling to enable audio systems to reach their full potential.
Vision
Clean Power and Earth are the Key
​
Our vision is a future where the true essence of music, captured in high-end audio systems, is completely unveiled. We believe that in this future, perfectly clean power and noise-free ground are no longer an optional upgrade but the unquestionable, integrated foundation of every high-end listening experience. We strive to position Haandrikman Audio Systems globally as the technological leader and the ultimate reference standard for power and ground management in ultra high-end audio.​​​

Specialization
Eliminating Mains Noise
Haandrikman Audio Systems specializes in the development and supply of ultra high-end power solutions for the most demanding audio installations. Our core focus is on eliminating noise and interference in the electrical power and ground connections to guarantee the purest sound reproduction. This is achieved through two main product groups:
​
â–º Precision Cabling
High-quality power and grounding cables engineered to minimize electromagnetic interference and ensure a stable, unimpeded power flow.
â–º Integrated Power Systems
All-in-one devices that seamlessly integrate power distribution, active filtering, and advanced conditioning of both power and ground connections into a single chassis. These systems serve as the heart of the power supply, maximizing the dynamics, resolution, and musicality of the connected components.
Unique Technology Highlight
Active Earth Conditioner
A hallmark of our innovation is the Active Earth Conditioner (AEC), a technology uniquely implemented in our flagship product, the Sygnus X-2. The AEC actively removes noise and pollution from the ground connection of the audio system.
​
The Listener's Benefit: Our proprietary AEC technology achieves an unprecedentedly quiet background, allowing the smallest musical details to emerge and elevating the audio experience to an unparalleled level of realism and musicality.
