Ground Boxes

Why use our Ground Box’s ?

You will get an improvement in dynamic’s, a lower noise floor and more natural flow in the sound.

For us a clean and effective ground point is one of the most important factor’s in ensuring the best possible sonic platform for any hifi system!
We normally say 220V 50Hz alternative110 V 60Hz. But in our opinion there are a lot more frequence on the power net. These is caused by the way we connect zero and protective ground together in the main central/fuse boxes.Most things these days run on electricity. Current goes in and current goes out of devices and lighting fixtures of every kind. All of these make the current messy. Not least computers with their switched power units, chargers for e.g., mobile telephones, all the halogen and LED lighting, dimmers etc. all cause a great deal of high-frequency noise and stay voltages. This noise always seeks the easiest path to the earth. And since this can be everything from 50-60 Hz to very high-frequency, but weak, currents, it is not always certain that the path of least resistance is via the protective earth. These currents instead can find dishwashers, laundry machines, counter tops with water pipes, your HiFi rack and your stereo set with all the cables and devices as more attractive paths to the earth. Moreover, these stay voltages often generate very large magnetic fields that absolutely have influence on the sound reproduction.
One big problem is that the protective ground many time are overloaded or not constructed for handle this pollutions. It can handle a real ”bang” of 110-220Volt and X Watts without any problems, but when it come to this small currents of some Milli V with very high frequence it dont catch them. So instead these will flow arround in the power system searching for a place to ground. And in fact the protective grond can leak back a lot of pollutions to the power net that instead go to f,ex your HiFi system with all the cables and magnetic fields and load up and rest there in their serch for ground.Our ground boxes / Eartha cables are designed to resemble and work like a bit of Mother Earth in concentrated form and offer the simplest and fastest route for this high-frequency noise to reach a earth point. Since such are very high-frequency weak currents, it is not necessary to have a lot of mass; but it is important that the cables are optimized for these high frequency and the groundbox be a purely attractive earth point.The construction and choice of materials in the earth box has a crucial effect on the result. In part, the minerals and metals involved have an effect, but the relationship of proportion and distance between them also affects the result.

When you connect your system to one of our groundboxes you offer this high frequence stay voltages a ground point where they can find peace instead of flowing arround in the system.

Today we have 2 lines ( Mini and Tellus) of groundboxes and 4 levels in each line, start with our entry level and first released models Tellus/Minimus to our latest released Olympus line,so we think you can find a box that fit your demand.
Since the connection cables have a huge impact on the result, we recomend you to choose Eartha cables with care. We have a wide range of Eartha cables from our entry cable Eartha Cupper to our top line Atlantis with all kind of connectors.
Please red more about Earth cables on our cable site..

The Olympus groundboxes are different from Minimus /Silver Minimus in many ways. When we developed the “Supercharger line” Atlantis we found many interesting details. Unfortunately we could not simply implement these ideas directly into the Silver MinimUs or Silver Tellus
without fundamentally changing the product

With the Olympus line we were totally free to implement all of our combined knowledge, using no fixed parameters to re-design from the ground up.
So in the Olympus line we have an all new mineral-mix, as well as a reduction of the quantity of some metal particulates, there is the inclusion of some all new metals ( for example Magnesium). Olympus MinimUs, like our other MinimUs, has only one outlet but in this case it is now solid Silver. Needless to say it is now the top model in the Mini Groundboxes.
Olympus is primary designed for ground Pre-amps and Dac’s. But it can also do a very good job with the grounding of our cables and our CleanUs line. The most significant difference in performance, compared to the Silver Minimus, is more texture and air in the lower frequency as well as more detail and better over all flow in the music.
Like our other ground boxes it is made of Oak but with the Olympus you can also order it in a dark Oak finish.
