With Entreq ground boxes you will get an improvement in dynamic's, a lower noise floor and more natural flow in the sound.
Once Entreq had developed the Eartha Infinity cables a new world opened up for them. With the knowledge about how the performance changed after Entreq treat the metals with high pressure, they decided to build a box where they have implemented the knowledge they get from the Infinity cables. The flow, the speed, the lightness, the punch, the joy, the musicality is what users answer when asked to point out what they value most with Infinity line. “Something you can´t get with any other gear”.
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.
Silver Tellus
The Silver Tellus has four dedictaed outlets and can handle up to eight devices. In addition to the enhanced design of the Silver Tellus, it also includes 30% more Silver in its specialist mineral mix. All of these advancements have resulted in a significant improvement in the effectiveness of the Silver Tellus to reduce noise and gain better dynamic's.
The careful choice of the "Ertha" cables used with the Silver Tellus is critical in obtaining its full potential in your system.
Specification :
- Four dedictaed outlets and can handle up to eight devices
- Weight: 22Kg
- Dimensions (WxHxD): 43cm x 14cm x 31cm
- Lifetime Warranty
UK Deliveries
Within the UK we aim to ship all items same day, however during busy periods it can take 1-3 days for dispatch. We ship all items with premium courier services which quote 1-2 days for delivery. Please note these times may be effected due to circumstances outside our control. Shipping is free on all orders over £50.
Ireland Deliveries
Following Brexit, We are still able to ship into Ireland, and no further VAT or charges apply. All Irish orders will dispatch from our N.Ireland warehouse, and therefore no charges apply. Shipping is free on all Irish orders over £50.00.
Europe Deliveries
For deliveries in Europe, we have two options which can be chosen by the customer.
N.Ireland - We can ship your goods from our N.Ireland warehouse, in which case we must charge VAT however due to N.Ireland's free trade agreement with Europe you will therefore not be charged any import duty or further costs. Shipping costs are calculated at the checkout based on destination.
Britain - We can ship orders from our British warehouse (UK Mainland) which will be charged ex VAT, however this will require export paperwork, and import duty and applicable charges will apply. VAT is removed at the checkout if your destination is applicable.
Non EU Countries
If you are purchasing from a Non-EU country, you will not be charged VAT which will be deducted at the checkout. Import duties and further applicable charges may apply depeding on your country. Shipping is calculated at the checkout based on destination.
We have several deomonstation areas in both of our branches. Please give us a call on 03435236169 or email support@kronosav.com to enquire about hearing products at your local branch.
