The HMS Energia series is engineered to provide the cleanest possible electrical foundation for high-performance audio and video systems. Developed through decades of research into interference suppression and power optimization, Energia products are designed to reduce unwanted electrical noise, improve system stability, and unlock greater musical realism.
At the heart of the series are HMS’s proprietary GLS (Ground Loop Suppression) and DCS (Direct Current Suppression) technologies. Together with carefully selected filtering materials and optimized internal construction, Energia products help eliminate transformer hum, reduce distortion, and preserve the integrity of the incoming power supply.
From compact front-end filters to advanced multi-outlet power distributors, the Energia range is designed to support everything from individual components to complete reference-level systems with greater openness, focus, dynamics, and natural tonal balance.
The Energia Power Filter Lineup
Energia MKII Basic
Essential Power Conditioning for High-Quality Systems.
The Energia MKII Basic is designed to provide effective passive power filtering for audio and video systems seeking improved stability and reduced electrical noise.
Using carefully optimized filtering structures and ferrite-based suppression technologies, it helps minimize interference from the AC mains while preserving dynamic performance and musical flow.
Available in multiple outlet configurations, the MKII Basic creates a cleaner and more controlled electrical environment for connected components.
The result is improved clarity, greater focus, and a more natural listening experience.
Advanced Power Purification for Reference-Level Performance.
The Energia MKII GLS/DCS combines HMS’s proprietary Ground Loop Suppression and Direct Current Suppression technologies to deliver advanced mains conditioning for high-end systems.
Designed to suppress transformer hum, reduce ground-loop related interference, and minimize unwanted distortion from the power supply, it creates a significantly cleaner electrical foundation.
Its optimized filtering architecture enhances low-level detail retrieval, dynamic precision, and overall system coherence while maintaining musical openness and natural tonal balance.
The result is a quieter background, greater realism, and improved long-term listening comfort.
Dedicated Front-End Filtering for Critical Components.
The Energia RC 1/1 is developed as a compact single-outlet filter designed for placement directly in front of sensitive audio components.
Using GLS/DCS technologies together with optimized filtering stages, it helps suppress interference, transformer-related distortion, and unwanted electrical artifacts before they reach the connected component.
Its focused architecture makes it particularly effective for source components, DACs, streamers, and preamplifiers requiring maximum signal purity.
The result is improved resolution, greater spatial stability, and enhanced musical refinement.
Expanded Filtering Performance for Complete Front-End Systems.
The Energia RC 3/1 extends the RC concept with additional filtered outlets for systems requiring advanced power conditioning across multiple components.
Combining GLS/DCS suppression technologies with carefully optimized internal filtering networks, it reduces electrical noise while preserving dynamics, timing accuracy, and musical realism.
Its multi-outlet configuration makes it ideal for complete front-end chains including streamers, DACs, preamplifiers, and digital sources.
The result is greater coherence, lower background noise, and a more open and focused presentation.
Reference-Level Power Distribution for Demanding Systems.
The Energia RC 4/3 represents the most advanced implementation of HMS’s power filtering technologies within the Energia lineup.
Designed for high-current applications and complete reference systems, it combines dedicated filtered outputs, advanced suppression technologies, and carefully optimized internal layouts to preserve stability under demanding conditions.
Its architecture separates high-current amplifier connections from source components, helping maintain maximum performance throughout the entire system.
The result is improved control, greater transparency, deeper silence, and a more natural and emotionally engaging listening experience.
Energia embodies HMS Elektronik’s long-standing expertise in interference suppression and power optimization.
Combining proprietary GLS and DCS technologies with carefully engineered filtering architectures, the series is developed to preserve the purity of the incoming power supply while minimizing unwanted electrical artifacts.
Every Energia product is designed to create a quieter, more stable, and more natural electrical environment for high-performance audio systems, helping components perform with greater precision, dynamics, and musical realism.
Energia represents HMS’s philosophy applied to power delivery: technical refinement in service of uncompromised musical performance.
