Heimdall 3 Power Cable

Norse 3 Power Cables

Norse 3 Power Cords are designed around a clear principle: the integrity of the power delivered to audio components matters. Every element of their construction is engineered to control electrical and mechanical behaviour, creating a stable, consistent AC connection that allows audio components to perform their best. 

Built around Nordost’s Mono-Filament technology, Norse 3 Power Cords use solid core, silver-plated OFC conductors to minimise interaction with insulation and support the rapid delivery of AC power. Norse 3 also employs Mechanically Tuned conductor lengths, further optimising performance and minimising timing inconsistencies. 

Norse 3 Power Cords go even further by introducing AC-optimized shielding to their design, adding an important layer of isolation between the conductors and their electromagnetic environment. By containing the electromagnetic energy generated by the cable, while reducing the susceptibility to external electromagnetic and RF interference, shielding creates a much-needed, controlled electrical environment in the sonic ecosystem. 

Norse 3’s holistic approach to low-loss construction, mechanical control, and electromagnetic isolation provides a stable, refined foundation for the entire system, helping preserve tonal colour, texture, and fine detail. 

Heimdall 3

Every audio system is an ecosystem, where the performance of each component, cable, and connection depends on the conditions in which it operates. Nordost’s Heimdall 3 Power Cord optimises this environment, combining low-loss construction with AC-optimized shielding to provide a more controlled path for power delivery. Utilising Nordost’s proprietary Micro Mono-Filament technology, each of its three 16 AWG silver-plated, solid-core OFC conductors is wrapped in an FEP filament before being encased in extruded FEP insulation. This creates a virtual air dielectric around each conductor, supporting rapid power transfer and providing mechanical damping. Mechanically Tuned Lengths optimise conductor resonances, while 90% overall shield coverage helps reduce susceptibility to external interference while containing noisy electromagnetic energy that would hinder the performance of the cables that surround it.
