Silver Tellus Tungsten GroundBox

With a working mass of 20kg and featuring an improved mineral mix including tungsten and titanium, the Silver Tellus Tungsten is a versatile ground box suitable for use in many audio systems. It includes 4 binding posts in a two-cell construction. This means you can attach digital sources to one cell and analogue sources to the other. The Silver Tellus Tungsten can also be used for negative speaker grounding.

Silver Tellus is undoubtedly our best-selling ground box. Thousands of users worldwide use it, and it can be said that Silver Tellus is something of a legend. The longest and most-read thread on What’s Best Forum is about Silver Tellus. Now, after more than a decade, we introduce a completely redesigned version of this legend.

We have updated the mineral mix to match the one used in our Olympus Tungsten boxes. We have modified the chassis so that Silver Tellus Tungsten now features two separate chambers. This means you can separate analogue and digital signals, using two connections for analog devices and two for digital ones. You can also use the Silver Tellus Tungsten to ground the negative terminals of the amplifier’s speaker outputs. We have retained the format but improved the chassis against vibrations and now deliver custom-made aluminium spikes (not pictured, but included).

This ground box works most effectively when grounding/draining up to two components with a total weight of between 10 – 100kg.

It also works well for grounding all types of power distribution.

This is only a guide and you will find that it will still have a positive effect on larger components.

Negative Speaker Grounding
This box works well for negative speaker grounding on all amps.

Please note that grounding the negative speaker post on amplifiers can have a significant impact on your sound quality. 

Eartha Cables
For the highest quality in all applications, we recommend using Silver Tellus Tungsten in combination with Eartha Olympus cables. However, you will find that the Eartha Sudoku, Eartha Revelation and Eartha Apollo cables will also provide excellent performance at a lower price point.
