A new generation Groundboxes with new technique and new materials 
Since the introduction in 2017, the Olympus Ten has been our most sought-after box. This was the first box with Infinity technology. Now we are proud to release the continuation of our efforts.Olympus Infinity Tungsten, a significant upgrade of Olympus Infinity. 
Whith new mineralmix, Ceramic and Tungsten we have reached a new level of performance.
A solid, silent, dark background gives 4 D sound as we never reached before.  

When you see the Tungsten logo with the Infinity eight it means we use the new developed tech with Ceramic and Tungsten. 
You can read more about these exiting materials if you follow the links.

                                             All our products are developed and tested on several different systems. In our own listening room we use Tidal Assoluta system.  

Olympus Ten T.

Together with an Eartha Olympus, you get a very powerful earth point that provides a very quiet and interference free background.
 
The biggest improvement over the Olympus Ten is in the lower and midrange frequencies. Experience an airy and lively bass quality and a kind of 4 D experience.
We also produced Olympus Ten T to meet all demands in a multi box.

Olympus Infinity T.

We have improved the Infinity technology, adjusted the mineral mix, added a special ceramic and added Tungsten to the metals. Together with an Eartha Olympus, you get a very powerful earth point that provides a very quiet and interference free background. 
The biggest improvement over the Olympus Infinity is in the 3 D feeling.
So strong that we like to say 4 D. Experience an airy and lively bass quality and a midrange that can rarely be achieved without grounding. You also get this extra ordinary 4D experience. Like when you use very good sunglasses a bright day.  
We also produced the Olympus T to meet all demands possible in a multi box. The Olympus Hero.

The Entreq Groundbox Principle

At Entreq we have many years of experience and knowledge with grounding. No other company have that.
Because of that we are one of the most copied brands in the world.
Through all that experience and knowledge we have landed on our core principle when talking groundboxes.

We use different layers of metals mixed With minerals to create a galvanic Point that acts like a concentrated piece of Earth.
By changing the metals, minerals, size, weight or case construction we get different performance out of the groundingbox.


Imagine the construction as a battery, but opposite. Instead of create and send out it pull back and consume


Olympus Infinity

Olympus Infinity Olympus Infinity

A statement for all groundboxes
Once we had developed the Eartha Infinity cables a new world open up for us. And with the knowledge about how the performance change after we treat the metals with high pressure, we decided to build a box where we have implement the knowledge we get from the Infinity cables.
A " cost no object" project where we use all our knowledge so far.The result is stunning.Our top of the range box Olympus Infinity is together with Olympus Infinity Tungsten by far the best ground boxes we ever made. Sorry to say also the most costly we ever made, but in our opinion they give the user full value for the money.
Together with our Olympus Eartha groundcables you will reach a 3 D soundreproduction that are exeptional.You will get a detailed, lifley soundstage from your system that you never can reach other way.

Olympus Ten

Olympus Ten Olympus Ten


Olympus Ten are the result of more than ten years of experience from groundboxes.
Olympus Ten is the first box where we use Infinity tech.The leap in performance compared with Silver Minimus is not subtle.
You will hear it right away. Of cource the bigger brothers Olympus Mini and Olympus Infinity have more solid effect, but we hardly believe you ever will find any other box in this size that give you so high performance for so reasonable price. 

Olympus Ten is the smallest box in the Olympus line. It is by far our most sold box.

Why use Entreq Ground Box's ?  


For us a clean and effective ground point is the most important factor 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.
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 stray voltages.

This noice 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 high freq often generate magnetic fields that absolutely have influence on the sound reproduction.

One big problem is the protective ground.
Many times it is overloaded or not constructed for handle this pollutions. They are not dangerous that way. 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.

In fact the protective grond can leak back pollutions to the net. 
Instead it often go to your HiFi system with all the cables and magnetic fields and load up 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 must attract so the groundbox be a purely attractive earth point.

When connect to a groundbox you offer this pollutions a ground 
This high-frequency, but weak currents, are atttracted by the galvanic mineralmix and the Para, Dia and Ferro magnetic metals.The high frequency currents move over to the box, where they will be transformed. 


Poseidon

Poseidon Poseidon


The Poseidon can be best described as three totally independent Olympus Minimus in one box. With its three pure solid Silver binding posts the Poseidon offers a level of performance & an almost limitless set of options that only Pluton can do better. One option in particular is the ability to now Ground each channel of your amplifier, via the negative speaker terminals,  while simultaneously & independently being able to Ground your Pre-amp or Dac at the same time. This option alone offers an unrivalled level of performance yet to be attained in any other single Entreq Ground box. This is just one option, there are so many more. Please contact us or your dealer for find out the best way to use Poseidon in your system.

Silver Tellus Infinity

Silver Tellus Infinity Silver Tellus Infinity



Weight 22 Kg  W 43cm - H 14cm - D 31cm
Silver Tellus Infinity with the new Infinity technology has like the old Silver Tellus 4 binding posts. But on S T Infinity 3 are linked together and 1 is separated, so you can use it for Wall socket or another source that you want have separated.
But S T Infinity are not made for neg speaker pole grounding. 

You hear straight away the relationship S T Infinity have with our flagship Olympus Infinity. A flow and punch in the music that is hard to find other way. There are something special with the Infinity technology that gives a flow and dynamic that are significant for Infinity. The mass of nearly 20 kg
(biggest cell we have) alow you hook up a whole system to the box. 
  Note : The Silver Tellus Infiinity with the mass of 20 kg can handle up to 8 units. It is a good idea not mix digital and analouge units to same S T.


Olympus Minimus

Olympus Minimus Olympus Minimus


Olympus MinimUs, has only one outlet but in this case it is solid Silver. 
Olympus Mini is primary designed for ground Amps and Dac's. But it can also do a very good job with grounding of our cables and our CleanUs line. The most significant difference in performance, compared to Olympus Ten, is the solid dark background in the sound caused of the fact that we have much more mass and weight in the box.it give a deep and massive low frequencies while still retaining the air and texture in the wider spectrum. Even if it not a Infinity box it still have all benefits from the Olympus line.

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 Tellus we 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 our normal solid Copper posts, gave us an even better noice reduction. In the Olympus Tellus we 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.
To be honest when we introduced Tellus 2010, we could never have dreamt that we could take grounding so far. We are just delighted that we have been able to produce something as good as the Olympus Tellus.
Note! Not for neg speaker pole.

We have created a guide for help you choose the size on the box so it best way meets your demands.                        Please contact us for more info if you have questions. We will be happy answer and guide you.

 
Silver Tellus, Olympus Mini, Olympus Infinity and Olympus Infinity Tungsten have an effective mass 8-20 kg.
They work well with all kinds of electronics besides Routers, Switches, and other devices with very low power consumption. This groundboxes are too effective to be used with such gears.The boxes above also work well for ground all kind of Power splits and Entreq Power Cords. Works good for neg speaker grounding on big Amps and speakers
Minimus, Silver Minimus, Olympus Ten and Ten Tungsten all have an effective mass around 1 kg.
They work well together with all Entreq cables and with electrical units with low power consumption as DACs, most Pre-Amps, CD players, Routers, Switches and so on. Also good for negative speaker grounding in all systems.
Note!
Negative speaker post grounding on Amps use to give a very good sound and is something we really recommend you do. All boxes besides Silver Tellus can be used for this kind of grounding.But before you do it, please download our manual or contact us for more info.
None of the boxes stated above can replace a protective safety ground.

Earth Cables Earth Cables

The choice of Eartha cable for your grounding system are at least as important as your choice of groundbox.  
Our Eartha cables are developed simulant together with our boxes for give best performance.
So with that said, always choose a original EA cable for your grounding system.

All Our EA Cable gives a neutral impression on the sound character.
However, the EA Silver are more focused on bring the details in the midrange treble more highlighted and in focus.
We would not say Eartha Silver is neutral, we would say it´s detailed.
EA Discover is a hybrid cable, Cupper and Silver. A good match for the boxes in our Silver Line.
EA Discover have a slightly warm character and let not the details write you on the nose.
However, if you want access to more details and airy sound you should use EA Apollo  which is a very good all round cable that fits all our boxes, both in the Silver Line and Olympus line.
EA Olympus are developed in first hand for match and be used with our Olympus boxes. All details, will show up in right shape and the tonal influence are subtle. An Olympus box with an Olympus cable just lower the noise floor and leave the tonal impression untouched. You will be surprised that your system can deliver so much more music and details without change the tonal balance.

K2, Everest and Peak 4 Tungsten

Minimus Infinity Minimus Infinity


K2, Everest and Peak 4.

We have always used wooden caps on our binding posts, wood is totally neutral and adds no new capacity and in that sense it is perfect. The opposite in fact to using plastic’s and most metals. 

We have used this fact to add our all-new features.
You simply replace the wood caps on your existing ground box with either the K2, Everest or Peak 4 product.
K2 use two different metals.
Everest we have mixed four metals.
Peak 4 have six metals and use Ceramic and Tungsten.
Trough the bindingpost you change the performance in the box.
That mean that you can fine tune the box so it´s optimal for you. 
You simply match the K2, Everest or Peak 4 to ensure optimal performance.
