Super Ground Cube

The Super Ground Cube reduces interference in the audio system and brings greater calm, depth, openness, and a more natural sound.

The Super Ground Cube is a special grounding element designed to audibly reduce interference in high-quality audio systems. The result is not a superficial effect, but a sound with greater order, more inner calm, and a clearly enhanced musical presence. Music feels freer, more colorful, and more natural.

Compared to the Signature version, the Super Ground Cube takes things a decisive step further. Playback gains in substance, openness, and expression. Fine structures become easier to follow, spaces appear more coherent while also feeling wider, and voices and instruments develop more body and presence. Even familiar recordings reveal more information and a stronger musical connection.

Unlike conventional grounding solutions, interference is not simply discharged into an already burdened earth. The Super Ground Cube follows its own approach, calming the entire sound picture and allowing more of what truly matters to come through: timing, tonal colors, space, and musical coherence.

For connection, the Super Ground Cube features a gold-plated, low-mass, low-eddy-current WBT terminal for spades and banana plugs. Included is a 1.2-meter cotton-covered cable with gold-plated beryllium copper hollow banana plugs, made in Switzerland.

An integrated switch allows the character of the Super Ground Cube to be adjusted in three steps to match the system:

The middle position creates an open, spacious presentation, the upper position adds warmth, and the lower position brings more substance and density. This makes it possible to fine-tune the effect to the system, the room, and personal listening preferences.

Installation is simple and flexible. The Super Ground Cube can be connected to a free socket on the power distributor, a wall outlet, or alternatively to a grounded metal point. For optimum performance, alignment along the north-south axis is recommended.
