“In practice, however, it does a lot.”

Dawid Grzyb, HiFi Knights

HANDCRAFTED IN GERMANY

Each Super Ground Cube is made in Germany from carefully matched materials and components.

FLEXIBLE TO USE

Connects via a power distributor, wall socket or earthed metal point, flexible anywhere in your audio system.

GREATER CALM IN THE SOUND

Controlled dissipation of interference supports a calmer, deeper, and more natural musical presentation.

Dissipation Instead of Grounding

a different approach to a calmer sound

Unlike conventional grounding solutions, the Super Ground Cube does not couple to the house earth, which is often polluted already. It forms its own calm reference potential into which selected ground points are drained, for a stable, clean electrical environment without ground loops.

Connection and Craftsmanship

gold-plated WBT terminal, cable made in-house

For the connection, the Super Ground Cube has a gold-plated, low-mass, low-eddy-current WBT terminal for spades and banana plugs. It comes with a 1.2 metre cotton-sheathed cable made in-house, wound and braided on our own machines, with gold-plated beryllium copper hollow banana plugs made in Switzerland.

More calm for the music

The Super Ground Cube reduces interference in your audio system and brings more calm, depth, openness and natural sound. The result is not a superficial effect, but a sound with more order, more inner calm and more musical presence. Music feels freer, more colourful and more natural.

Compared with the Ground Cube Signature, the Super Ground Cube goes one step further. Playback gains substance, openness and expression. Fine structures become easier to follow, spaces feel more complete and at the same time wider, voices and instruments gain more body. Even familiar recordings reveal more information and a stronger musical connection.

Draining instead of earthing

Conventional grounding solutions drain interference into the house earth, which is often polluted itself and can bring ground loops and installation problems. The Super Ground Cube takes a different route: the supplied cable connects selected ground points of your system to its own, inherently calm reference potential. Interference drains there in a targeted way instead of spreading through the house installation. The result is an electrically stable, clean environment that carries straight into the sound: better timing, clearer tone colours, more space and a more coherent musical picture.

Three-step sound tuning

An integrated switch adapts the character of the Super Ground Cube to your system in three steps: the middle position gives an open, wide presentation, the upper position more warmth, the lower more substance and density. This lets you tune the effect precisely to your system, room and taste.

Installation and orientation

Installation is simple and flexible. Connect it to a free outlet of your power distributor, a wall socket or alternatively to an earthed metal point. For the best effect, we recommend aligning it along the north-south axis.

Frequently Asked Questions about the Super Ground Cube

Where do I install the Super Ground Cube?

Connect it via a free slot on the power distributor, a wall outlet, or alternatively to a grounded metal point. For optimal effect, we recommend aligning it along the north-south axis.

What does the three-stage switch do?

The built-in switch lets you adjust the character of the Super Ground Cube to your system: the middle position provides an open, wide presentation, the upper position adds more warmth, and the lower position adds more substance and density.

What sets the Super Ground Cube apart from conventional grounding solutions?

Conventional solutions dissipate interference into the mains earth, which is itself often loaded. The Super Ground Cube instead uses its own, quiet reference potential: selected ground points are connected directly to the Cube via the included cable, so interference is dissipated there rather than spreading through the system. This avoids ground loops and creates an electrically clean environment.

What's the difference between the Super Ground Cube and the Signature version?

Compared with the Ground Cube Signature, the Super Ground Cube goes one step further. Playback gains substance, openness and expression. Fine structures become easier to follow, spaces feel more complete and at the same time wider, voices and instruments gain more body. The Super Ground Cube can also be tuned in three steps.
