Great Read: The Audiobeat review of the Entreq Grounding System
NOTE: Entreq has severed ties with their US distributor. This has made acquiring their products more difficult. As a result, we have found an alternative that actually works equally well and often times better. Pranawire Ruby Grounding box - The Pranawire Ruby grounding box is an alternative to the Entreq. It has a lower price point than the Silver Tellus, but can only handle 2 components. In our listening tests, the standard Ruby performed as well as the Silver minimus and Silver Tellus. Pranawire also offers the Ruby Ground Plane with a Duelund silver CAST capacitor internally. This further enhances performance beyond the Silver minimus and Tellus.
The Entreq Olympus Tellus
The Olympus Tellus weighs in at a massive 99 pounds (45 Kg). It possesses 6 inputs for grounding plus a separate input for grounding a wall AC receptacle. The Olympus Tellus has the same sonic signature as the Olympus, with deep and massive low frequency power and impact, while maintaining the delicate tonality microdynamics and air in the high frequencies.
The Olympus groundboxes are fundamentally different from both the Tellus & Silver Tellus. The idea for the Olympus was sparked when we designed the “ supercharging “ qualities of the Atlantis MinimUs & Tellus . There were so many unique and interesting details on this development that when we decided to make Olympus we had to free ourselves to implement all that we had learned with no fixed parameters. It was exciting, almost like starting a fresh. Poseidon can also be a good choice for those who find the Olympus Tellus either physically difficult to accomodate but want the Olympus benefits and where the single outlet on the Olympus MinimUs doesn't offer enough flexibility with connectivity.
The Entreq Concept - An Optimized Ground
The easiest way of thinking about the Entreq boxes is to literally consider them a box of "ground". made up of a controlled quantity of conductive materials known to absorb noise. This provides a far more consistent, reliable and potent grounding for your audio system than a grounding rod in your back yard (which you should have as well).
Think about it. Sink a grounding post into the earth and the precise make up of your soil, how wet it is and what other elements or pollutants it contains will all impact its effectiveness and nature as an electrical ground. So, as you can see, it’s not quite as simple as hammering a conductive rod into the ground. What Entreq has done is develop the best possible filler for their boxes, a mix that delivers consistent musical results despite its physical isolation from a physical earth ground. This is not a substitute for the main electrical ground on your system’s AC feed. It’s an addition, rather like a bypass cap, that improves the ground quality seen by the system rather than replacing the existing arrangement. It is also an essential first step in providing the best possible operating conditions for your system. Do not disconnect your main AC ground or you could create a dangerous and quite possibly lethal situation!
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 frequencies on the grid. They are caused by the way we connect zero and protective grounds together in the circuit breaker boxes. Current goes in and out of devices. All of these pollute the current.
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 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 stray 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 to handle this pollution. It can handle a real "surge" of 110-220Volt and X Watts without any problems, but when it come to small currents of some Millivolts with very high frequency they cannot catch them. So instead these will flow arround in the power system searching for a place to ground. And in fact the protective ground can leak back a lot of noise to the power grid.
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 ground boxes you offer high frequency stray voltages a ground point where they can find peace instead of flowing arround your audio system.
"...If you’ve got a clean ground, then the Entreq boxes will deliver a worthwhile upgrade on that arrangement. If you haven’t, then they represent the audio equivalent of a lifebelt thrown to a man adrift on the high seas. You may not have realized your system was drowning, but if that is all you’ve ever known..." - The Audio Beat
The Eartha Cables
Entreq has created an extensive range of dedicated Eartha cables. The properties of these cables have been painstakingly designed and constructed over many years,to offer a perfect match to their ground box's.They are constructed and maintain, very exacting parameters, while enabling specific & incrimental matching to each and every system they are employed within. With this in mind you will also find a wide range of connectors which allow you to attach & employ our grounding solution's in almost any conceivable scenario. Read more about your choice of Eartha cables.
Installing / Auditioning Entreq Grounding Boxes
Installing and auditioning the Entreq grounding products, like many tweaks will require patience and experimentation. Try to refrain from snap judgements as it takes a little time for changes in their cables and the box itself to settle in. For example, if you are trying the Copper vs. Silver Eartha cables, allow the cables to settle in overnight before making serious evaluations.
Note: Beware of mixing signal and chassis grounds from one component, as it most always muddies the waters. In most cases, working on the signal ground first (vs. chassis ground) is best.
Note: Where possible please ground digital & analogue cables to seperate ground points.
Where to start?
First, there’s no substitute in terms of cost effectiveness or benefit to the installation of a proper clean, dedicated ground. Used in conjunction with a dedicated AC line, this is the absolute baseline for optimized system performance.
We prefer working with signal grounds initially. The best place to start is with a Tellus. One standard Tellus with two copper Eartha cables costs only a little more than a Silver Minimus and Silver cable, and it’s a lot more effective overall. You can add a Minimus for your source component and extra cabling at a later date. However, if you have a serious system or you are serious about performance, then you should really head straight for the Silver Tellus, ideally with matching silver cables, and build from there. It might seem like an expensive option for what is essentially a ground, but its benefits are system wide, fundamental in nature and there’s no other way of achieving them.
Important Notes & Tips
- The Tellus grounding boxes not designed to replace the protective ground on your electrical mains!
- Where possible please ground digital & analogue cables to seperate ground points.
- Be careful with your choice of Eartha cables used with the Tellus grounding boxes. They are critical in obtaining their full potential in your system.
