Entreq have spent decades refining grounding, field shaping, and system optimisation techniques. Yet one issue has remained largely unaddressed in the wider hi-fi world: the silent disruption caused by electromagnetic fields entering your system through its two most exposed points – the power connection and the network cable.

These entry points, obviously completely unavoidable, act as invisible gateways for high-frequency noise, vagabond currents, and field interactions that degrade musical resolution, destabilise imaging and flatten the emotional impact of music. The thing is, most listeners don’t even know these problems exist.

You can upgrade components, swap cables, even rebuild your rack. However, none of that will resolve the field-based pollution quietly entering through your power and network connections. This issue simply doesn’t respond to traditional upgrades. That’s why Entreq created Magneus.

Based on years of research into electromagnetic behaviour in high-end audio systems, Magneus is part of a new product category Entreq call Electromagnetic Field Transformers (EMF Transformers). These devices operate without electrical connection. They don’t touch the signal. But the impact they have is unmistakable.

Magneus is joined in this new category by the MaxMix T2 Kit and the Protectus, each with a specific role to play in shaping and calming the energetic environment around your cables and components.

• Magneus Signal – for network, USB and HDMI cables and analogue signal cables
• Magneus Power – for power and speaker cables
• Magneus Supreme – a circular array creating a full-field chamber for maximum effect

Each is based on the same principle: field shaping through carefully selected materials and precise internal geometry. There are no filters, no electronics and no signal connection, only a profound rebalancing of the electromagnetic environment through which audio travels.

Every cable that carries current, whether for power or signal, generates magnetic fields and microscopic vibrations. These fields overlap, interfere and induce unwanted currents in surrounding components, creating an invisible web of interaction that subtly undermines sound quality.

Entreq Magneus doesn’t block or filter these fields. It shapes them. Through a carefully composed internal structure of paramagnetic and dielectric materials, it creates a calmer electromagnetic environment around the cable allowing music to emerge with greater clarity, focus and natural energy.

There’s no power, no tuning and no direct contact with the conductor. Just applied physics, silently at work in service of the music.

• Internal geometry: precise layout and orientation for targeted field interaction
• Material mix: reactive elements chosen for their magnetic and electrical properties
• Passive by design: no circuit, no modification, only field guidanceMagneus is sometimes mistaken for a ferrite ring or a type of transformer but this is not the case. Unlike a saturation transformer, which absorbs energy and can store or release it in unintended ways, Magneus operates with a very different intent and effect.
  • Field shaping vs. suppression: Magneus guides field behaviour, rather than dampening it outright
  • Open, interactive structure: not enclosed or magnetically “sealed” like typical transformers
  • Stable behaviour: no saturating components, no long-term energy build-up

  A saturation transformer acts more like a passive brake. Magneus, by contrast, aligns and harmonises the surrounding electromagnetic fields, improving system balance without dulling dynamics or tonal nuance.

  ” Its just a ferrite right?” The answer is simple: No. Ferrite rings are common in mass-produced electronics. They absorb certain types of RF noise, usually in the MHz range, by using a single-material core to suppress specific interference.

  Magneus is something entirely different in function, in materials and in behaviour.

  • Materials: A complex, reactive blend with varying magnetic and electrical properties, not just ferrite.
  • Geometry: Structured internal architecture designed to guide and shape fields, not just absorb them.
  • Function: Field transformation, not suppression. It’s passive, but purposeful and dynamic.
  • Results: If you think it’s the same, try both. In a transparent system, the contrast in clarity, tonal depth and spatial ease is immediately apparent.Long-time Entreq users will be familiar with their AC Wraps, which also act on the electromagnetic environment around power cables. While still highly effective and fully compatible with Magneus, they were developed more than 15 years ago.With everything they’ve learned since, if we were starting from scratch today, AC Wraps would likely not exist, Magneus would. It represents a new level of understanding, refinement and audible result.
  • While Magneus was developed specifically for high-end audio, their internal testing has shown that its electromagnetic field-shaping properties can also benefit AV systems. When placed on the power cable feeding a high-quality television, they’ve observed visible improvements in image clarity, contrast, and onboard sound performance. It’s a reminder that field noise is not only audible but can be seen as well.Founder Per-Olof shares this anecdote: “I was listening to Crocodile Shoes by Jimmy Nail — a track I’ve heard many times. But when I inserted the Magneus into the system, I noticed something I’d never heard before. The double bass I had assumed was playing a simple, repeating note turned out to be playing a melody. That low-end clarity had been buried under field noise all along. Magneus revealed it.”The moment you hear it for yourself, it’s hard to go back.Explore the two other Magneus models (linked below) and experience for yourself how calming the field environment transforms not just the sound, but the connection to the music itself.
