Entreq Earthing Systems

Unique Grounding boxes - earthing connection systems from Sweden
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.
Entreq was founded 1999 and are today, a truly Swedish company, we are one of the very few companies that develop,manufacture and produce our own products. Because of this approach you will never see us imitate other brands or their technical solutions. Consequently our products are not only distinctive in their constructive materials & design but also in their connective processes.

This control over each and every aspect, in conjunction with our unique philosophy and design brief, means we are able to focus purely, with no compromise, on performance.

Performance first !
This may sound like a natural aspiration in the field of audio but in our opinion this is rarely the case!

As a company we are continually searching for new factors that influence as well as improve the performance of our products. We will always use the listening experience as the true measure of musical success. If we can then calculate the reasons as to what and why, so much the better, but that is actually far less important.

“ What you can measure is not important, and the important cannot always be measured ”

There is quite a lot of truth in that sentence, even if it is not completely correct. 
We at Entreq trust more what we hear and experience than what the gauges tell us. If this sounds better than anything else, then it is. It is that simple, even if you perhaps cannot explain it scientifically with measurements.

We remember back in 70, when all should be measure in lab. At that time it was DIN  45 500 that tell us everything. It was DIN Watt, IM dist, HM dist etc,etc.If it not measure good enough, it been solved with negative feedback and all good .

Many times the stuff sounds bad, but if the measurement was so good, it must be good, that´s it.
It was a sensation when Matti Otaala from Uleaborg university explain why some amps that only give 20 W by Din 45500 sound so much more powerful than amps that give 200w by same norm.
What we mean is that we sometimes don’t know what to measure and what make sense.
And for you who say everything can be measured, could you kindly inform us of how you exactly measure the speed of an object in motion? 
Over the years Entreq has consistently received plaudits from around the world for its innovative products. The quality of design, craftsmanship and most importantly, musicality, have been recognised as the heart beat of every product.
 
We are proud and delighted to say that the editors and writers of " The Stereo Times " have awarded the accolade " Most Wanted Component 2012 " to not only our entire line of Apollo cable products, but in addition, our current top of the line Silver Tellus Ground Station. In 2015 we get the same fine award for our whole Power management system, included Apollo Powerus, Cleanus and Olympus Tellus These awards are reserved solely for exceptional products that offer only the highest standards of performance.
 
We also are extremely proud for get the AV Magazine award - Super AV Awards Outstanding Overall performance award 2014 for Silver Tellus.  
2015 we get the same fine award for our Powercord Konstantin 3V and also for Olympus Tellus.
 
We hope you take the time to listen and appreciate what many reviewers and music lovers have came to recognised about our extensive range of products.
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. 

The Tellus line with Minimus, Silver Minimus, Tellus II and Silver Tellus are all based on the mineral/metal mix we used for nearly ten years now.

When you read tests and reviews it´s always this boxes they use as reference. The first boxes we introduce on market.

Two years ago we introduce our Olympus line with improved performance in all parameters

In the Olympus we use a new developed mineral/metal mix wich give you a big leap in performance.

The Olympus line include Olympus Tellus, Olympus Mini, Poseidon and now our newest box Olympus Ten.  With the Olympus Ten we now have completed the Olympus line and we are happy to offer a Olympus box for all demands and budgets.

The Atlantis Minimus and Atlantis Tellus are boosters that in first hand was made for use with Tellus line for give that line nearly same performance as Olympus line. You can connect  both the Tellus and Olympus line to Atlantis for even better performance.
