Eartha Infinity line.

A milestone in Entreqs history

It is hard to believe that an Earth/Grounding cable could have such a huge impact on the sound quality!  

The way the cables used to drain away the noise / stay currents are designed has an signify effect on the result. We believe this is due to there being such a high frequency and low voltage in the current with which we deal.  When we developed the Apollo Network cable Apollo RG 45 we more or less stumble in to one of the most breakthroughing developments so far regarding earth cables and grounding. We test with expose the conductors for very high pressure. When this conductors was used for signal transmission it was not a big hit. But for grounding it´s one of the biggest improvement we ever came across.

There are many theorys why we get this improvement when we treat the conductors with high pressure. To be honest we don’t know which or what it is who make this big improvement, and frankly speaking we don´t care at the moment. The important is that this is one of the biggest leap in grounding for us so far.

Another detail is the wood tube on all of the Eartha Infinity cables. Also we are not sure if it´s because it reduce vibrations or radiation that we notice a significant improvement with the wood tube on Eartha Infinity.  

Spontaneously, you feel that the design of a cable not used to convey signals, but rather to connect to the earth, should not have any effect on the sound.

However, the choice of materials and the design of the earth cable produces completely different results. Again, we can only find the explanation in that it is a matter of very high frequencies, or else there should not be so big difference between connectors, regular copper cable and mirror-twisted silver cable.

Actually, it is merely the design of the contacts and the dialectrum that join a good earth cable with a good signal cable.  Otherwise, they have hardly anything else in common.

We began to market Eartha Cupper in 2010, and since then we have expanded the assortment with  7 other lines, where Eartha Infinity Olympus is our top cable.

Eartha Infinity Cupper.                           Produces a warm effect.

Eartha Infinity Discover                         A hybrid cable with good details and neutral.

Eartha Infinity Konstantin.                    Produces more detailed effect, but still warm

Eartha Infinity Challenger.                    A hybrid Copper/Silver that is rather neutral and with  very good details.

Eartha Infinity Silver                              Produces a very detailed effect, especially at high frequencies.

Eartha Infinity Apollo                            Neutral, but very open and detailed. Our most allround cable.

Eartha Infinity Atlantis                           For the best systems. Very detailed, with a warmer character

Eartha Olympus                                     For the best systems. Compareable with Apollo in sound but far more detailed. A winner.

It is simply not possible to offer any general advice as to which cable performs best in a stereo set.

Since each cable has its own properties, as does each stereo set, and they must be matched with the right ground box, so one needs to experiment.

In general, we can say that Discover, Challenger, Apollo and Olympus always work well. They are very all-round and neutral.

But we can unfortunately not offer any good advice about choose cable since the conditions vary so greatly.

However, the most expensive is not necessarily the best for you. It is very possible that Konstantin is the cable that does the best job for you.

Our recommendation is that you work with an experienced agent, dealer or distributor to secure the optimal combination of both Ertha ground cable and Entreq ground box to best suit your system.

Ertha RCA , XLR, DIN, USB& RJ45, Hook  : Standard length 1.65m ( longer lengths are available )

  • These cables are designed for direct connection to your electronics / computer / music streamer via currently unused RCA , XLR or USB inputs or outputs. The RJ45 connector can also be employed on your Digital streaming device but is most effective on your source router and/or NAS drive.
  • The cable is terminated with an Entreq spade at one end (this connects to your carefully chosen level of partnering Entreq ground box) and then to either an Entreq designed RCA , XLR , USB or RJ45  ground connection, at the other end. This then connects to your selected piece of equipment.
  • A carefully selected Entreq ground box is required to connect to your chosen Entreq Ertha cable.
  • These Ertha cables are available in the following ranges and are in an ascending order of performance :       

        Copper , Discover, Konstantin , Challenger , Silver , Apollo , Atlantis and Olympus

Eartha Schuko, US & UK

  • These cables are designed for connect to wall socket protective ground and either to a Stand alone Tellus/Silver Tellus or on the dedicatet input on Olympus Tellus. We don’t recommend you mix in other ground cables on ground box when using Tellus/ Silver Tellus
  • The cables are terminated with a plug that only connect to the Earth.
  • ​These cables are available as

          Konstantin, Challenger, Apollo, Atlantis and Olympus

Ertha Spade to Spade, hook/spade or Banana/hook : Standard length 1.65m ( longer lengths are available )

  • These are used to connect to equipment that have additional or specialist ground points, even chassis locations. The most common application is for negative speaker out grounding.
  • Entreq PowerUs and CleanUs products all have there own dedicated ground connections and as such require an Ertha Spade to Hook to draw excess noise away to your chosen Entreq ground box.
  • A carefully selected Entreq ground box is required to connect to your chosen Entreq Ertha cable.
  • These cables are available in the following ranges and are in an ascending order of performance :

       Copper , Discover, Konstantin , Challenger , Silver , Apollo , Atlantis and Olympus

Ertha 3.5 to Spade : Standard length 1.65m ( longer lengths are available )

  • There is only one application for this particular product and that is to exclusively connect, via a 3.5mm ground connection, to Entreq's dedicated "EEDS noise reduction circuit". This unique technology is built into almost all of Entreqs Signal cables.
  • A carefully selected Entreq ground box is required to connect to your choosen Entreq Ertha cable.
  • These cables are available in the following ranges and are in an ascending order of performance : 

       Copper , Discover, Konstantin , Challenger , Silver , Apollo , Atlantis and Olympus
