With Entreq ground boxes you will get an improvement in dynamic's, a lower noise floor and more natural flow in the sound.

Entreq has four levels of groundboxes and with each level there is two lines. They start out with their entry level which is the Tellus and Minimus. At the other end you have the Olympus range. We think you can find a box that fit your personal demands.

For Entreq 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!

They normally say 220V 50Hz alternative110 V 60Hz. But in their 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 fix your HiFi system with all the cables and magnetic fields and load up and rest there in their serch for ground. Entreq 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 their groundboxes you offer this high frequence stay voltages a ground point where they can find peace instead of flowing arround in the system.

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.

Olympus Tellus

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

With the Olympus line they were totally free to implement all of their combined knowledge, using no fixed parameters to re-design from the ground up. So in the Olympus Tellus they have seven grounding posts and employ an all new mineral-mix. As well as a reduction of the quantity in some metal particulates. There is also the inclusion of some all new metals, one of which is Magnesium. This together with six all new solid Silver binding posts, instead of their normal solid Copper posts, gave us an even better noice reduction. In the Olympus Tellus they have also employed one special solid Copper binding post that is completely isolated from the other six Silver grounding posts. This can be used for connecting a specific new mains Eatha cable. This can give a direct connection to the protective ground found in your mains sockets. This reduce's the noise floor significantly! It can of course also be used for other purposes.

The Olympus Tellus offers the same overall sonic signature as the Olympus Minimus. Deep and massive low frequencies while still retaining the air and texture in the wider spectrum. The separate outlet, allowing direct connection to a wall socket, (the protective ground) will give you a whole new experience. Connection to the protective ground gives an even darker background and will let you explore more subtle nuance and details within the music.

Like their other ground boxes it is made of Oak but with the Olympus you can also order it in a dark Oak finish.
