Its difficult to understand and believe that an Earth/Grounding cable can have a impact on the sound quality, but it clearly does.

There is no one cable fits all so Entreq offers 6 different sounding cables to suit the presentation and sound of your system.

Eartha Copper grounding cable produces a slightly warm effect.

Eartha Konstantin grounding cable produces a warm and little more detailed effect

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

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

Eartha Apollo Neutral, but very open and detailed.

Eartha Atlantis Very detailed, neutral.

These cables and the Entreq Earth boxes simply have to be tried so you can experience the full potential of your system.

The Spade to Spade grounding cable is typically used for grounding the negative terminal of one channel of your amplifier and connecting the other end to the draining terminal of the Entreq grounding device. You must never connect two draining wires to the same terminal when connecting to your amplifier negative outputs. 2 Entreq boxes are required or a multi ground device such as the Entreq Tellus 2, Silver Tellus or Poseidon
