Entreq Olympus Powerus Every component in your system ultimately converts mains power into sound. The quality of that power — and the way it is distributed — has a direct and audible influence on the final result. Yet power distribution is often treated as an afterthought: a standard multi-way extension, outlets daisy-chained together with no consideration for how interference travels between connected components. The Olympus Powerus takes a fundamentally different approach. It is not a filter or a conditioner. It contains no active circuitry of any kind. Instead, it focuses on providing the cleanest, most direct path from your mains supply to each component, using construction principles and materials chosen specifically to minimise interference at source. Star Ground Topology At the heart of the Olympus Powerus is a star ground design. Rather than daisy-chaining outlets in series — where each component's ground is influenced by every other component connected before it — each of the six outlets is wired independently back to a single central ground point. This eliminates ground loops between components and ensures that every piece of equipment in your system receives an equal, uncontaminated path to ground. Ground loops are among the most common sources of hum and noise in audio systems. A star ground topology addresses them at the distribution level, before they have a chance to affect your signal chain. Built for Purpose The Olympus Powerus uses an asymmetrical internal design with cabling optimised for high-frequency handling. It contains no magnetic materials, removing potential sources of interference from within the distribution block itself. The six Furutech NCF outlets are selected for their low contact resistance and resonance-damping properties, ensuring that the connection between your power cables and the distribution block is as clean and stable as possible. There are no filters, no current-limiting circuits, no compromises. Grounding the Powerus The Olympus Powerus features a copper binding post, allowing it to be connected to an Entreq ground box via an Eartha ground cable. This provides the distribution block with a dedicated ground reference, further reducing the noise floor across your entire system. For the greatest impact, Entreq recommend pairing it with a Silver Tellus Tungsten or Olympus 10 T ground box. The Olympus Powerus also works particularly well alongside an Entreq Cleanus. The Powerus distributes clean power while the Cleanus draws high-frequency contamination away from the supply. Together with Entreq grounding, they form a comprehensive power and noise management solution. Who Is It For? The Olympus Powerus is for the listener who has invested seriously in every other element of their system and wants the power distribution to be equal to the rest of it. If you are running components at this level, the mains distribution block is not a detail — it is part of the foundation.
