Entreq - Tellus - Ground Boxes - New
Because a proper clean ground is vital to actually realizing the potential performance of your audio system.
The Entreq Concept
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!
"...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
