Entreq
Swedish maker specialising in grounding. Entreq build passive boxes filled with mineral and metal compounds that give stray noise on a component's chassis somewhere to go, rather than filtering the mains.

What Entreq mean by grounding, and why it is not mains conditioning
Entreq work on a problem most of the industry addresses from a different direction. Mains conditioners clean the electricity going into a component. Entreq's ground boxes do nothing to the mains at all. They give noise that has already accumulated on a chassis a path away from the signal circuitry.
The boxes are passive and contain no electronics. They are filled with a mix of minerals and metals that Entreq will not fully specify, connected to a component's earth or chassis point by a dedicated cable. There is no filtering, no active circuit and nothing in the signal path, so there is nothing in the chain that can add distortion of its own. It remains a system-dependent product: some components respond far more than others, and a ground box is not a substitute for a mains protective earth.
That is worth saying plainly, because grounding is an area where scepticism is reasonable and Entreq attract more of it than most. It is a product best judged in your own system rather than argued about in the abstract.
Per-Olof Friberg founded the company in Sweden and still owns it. He spent more than thirty-five years as a farmer before releasing the first Tellus ground box in 2007, and says that work is where his thinking came from. Alongside grounding, Entreq make cables, racks, passive mains conditioners and isolation products, all using the same materials thinking.
