The Entreq Tellus and Silver Tellus Grounding Boxes are an essential part of a high performance audio system. They help to lower the noise floor of all attached audio components by optimizing the relative ground potential which results in a much more musical presentation. The Entreq units do so without adding any sonic signature of their own, which is a remarkable achievement since this ensures a wide compatibility with solid-state and vacuum tube based low and high efficiency systems.
There are five Entreq Grounding Cables with choice of spade-spade or banana-spade termination for use with the Tellus and Silver Tellus Grounding Boxes:
- Eartha Copper $US99/$US129
- Eartha Challenger $US379/$US429
- Eartha Silver $US479/$US529
- Eartha Apollo $US669/$US849
- Eartha Atlantis $US1469/$US1639
The quality of the grounding cables connecting the components to the Entreq Grounding Boxes is absolutely critical to maximize system performance. The What’s Best Forum has an excellent discussion thread on the Entreq Tellus and the overwhelming consensus is that the Eartha Atlantis is the preferred grounding cable to use.
Audio Sensibility offers its own OCC Copper and OCC Silver Entreq-Style Grounding Cables which offer an incredible price/performance to allow Entreq Tellus owners the opportunity to maximize their system performance when the budget does not allow purchase of the higher-end Entreq Grounding Cables.
Oyaide, the Japanese distributor of the Entreq Tellus and Silver Tellus Grounding Boxes, also manufactures Copper Entreq-Style Grounding Cables and Silver Entreq-Style Grounding Cables for the Japanese marketplace.
Audio Sensibility Entreq-Style Grounding Cables use an Eichmann Bullet RCA connector instead of the wood RCA connection which Entreq uses. We use the Eichmann Bullet RCA (with center pin not connected) because it is low mass/minimal metal/very durable and can withstand many insertion cycles without losing its mechanical integrity.
Audio Sensibility Entreq-Style Grounding Cables come with the standard 30 day money-back guarantee.
