Some hi-fi products explain themselves in a sentence. Entreq's new Magneus range is not one of them.
There's no plug, and no electrical connection to your system at all. Nothing is added to the signal path. You unplug a cable, pass it through the hole in the middle and plug it back in. That's the whole installation.
Entreq call these semi-passive electromagnetic field transformers, built from wood, tungsten, aluminium, copper and brass — paramagnetic and dielectric materials arranged to act on the electromagnetic field around a cable rather than the current running through it. If you're reading that with a raised eyebrow, fair enough. We're not going to try to win this one on paper.
What we will say is that the demonstration is unusually honest, because the thing goes on and comes off in seconds. Either you hear it or you don't, and you'll know within a track.
The Magneus Signal (£380) is the one that fits the cables most systems already have — network, USB and HDMI, analogue interconnects, and Eartha ground leads running back to a Ground Box. The Magneus Power (£880) is the larger unit, made for power cables — Entreq suggest close to the IEC inlet, the wall plug or the distribution block — and for speaker cables near the binding posts.
Magneus Supreme (£2100) goes furthest: eight vertically oriented elements in full 360-degree symmetry, forming a chamber around the cable rather than sitting on it. It's aimed at the feed to a hungry amplifier, or the main inlet cable to a distribution block.
