It is 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.

A special custom RCA/XLR connector is at the component end of the cable, and at the other end is a spade to connect to your Entreq grounding box.
