Entreq Eartha Apollo Ground Cable

The Eartha Apollo is Entreq's long-established silver ground cable, designed for use with their range of ground boxes. After more than a decade on the market, it remains one of the most trusted ground cables Entreq make — a reliable performer across a wide variety of systems and components.

Construction

The Eartha Apollo is built from solid silver, cotton, and wood. The silver conductors are twisted using Entreq's own developed system and then treated with a high-pressure process to optimise performance when used with Entreq ground boxes. The cable features a single 15 AWG conductor made up of four different AWG twisted pure silver threads. Pairs are spun both clockwise and anticlockwise — a deliberate construction choice that Entreq developed over many years of refinement.

Termination

All Eartha ground cables are terminated at one end with a hook connector for connection to the ground box. The other end is hardwired as standard at the time of ordering, which Entreq consider the optimal termination for performance. If you prefer flexibility, a bayonet (Level 3) or 3.5mm male (Level 1 or 2) connector can be specified in place of hardwiring. A bayonet connection offers the next best level of performance to hardwiring; the 3.5mm jack sits one level below that.

Who Is It For?

The Eartha Apollo suits anyone already using or considering an Entreq ground box who wants a capable, proven silver ground cable. It works across the full range of Entreq ground boxes — from the Silver Minimus Tungsten through to the Olympus Infinity T — making it a practical choice whether you are starting out with grounding or expanding an existing setup. It is not Entreq's most advanced cable, but it took them seven years to develop something that outperforms it, which tells you something about where it sits.
