The Ruhr Power Cords are sophisticated high quality cables giving your electronics the AC they are entitled to.

You are only satisfied with the best technology resulting in an astonishing clarity?

• Design wise, the Ruhr Power Cords have both the hot and neutral conductors spiraling around the inner group of ground wires. The relationship between the hot and neutral groups is fixed and non-changing, contributing to one of Black Cable’s most basic design qualities: consistency.
  So, thanks to the best technology, you get an astonishing clarity.

You want a significantly better dynamic contrast?

• As with all other Black Cable models the Ruhr Power Cords use solid pure copper conductors with a particular 0.6 mm diameter. This prevents strand interaction, a major source of distortion.
• Copper quality is critical because a conductor can be considered a rail-guide for both the electric fields within a conductor and for the magnetic fields outside the conductor.
• The purity of the solid pure copper conductors minimizes distortion as well as eliminates harshness and greatly increases clarity.
  So, thanks to the best technology, you get a significantly better dynamic contrast.

You want an exceptionally clear, clean and dynamic sound?

• The Ruhr Power Cords use solid polyethylene insulation on both its hot and neutral conductors because polyethylene not only is low-loss but also has an easy-on-the-ear distortion profile. Thanks to the solid polyethylene insulation, the Ruhr Power Cords have a lot less of the out-of-focus effect that you will hear with other insulation materials.
• The Ruhr Power Cords have identical conductors for the hot and neutral sides.
• The Ruhr Power Cords use our special non-woven taping to dampen spurious vibrations.
  So, thanks to the best technology, you get an exceptionally clear, clean and dynamic sound.

You want 3D dimensionality?

• All solid pure copper conductors are individually insulated with solid polyethylene so as to dampen distortion.
  So, thanks to the best technology, you get 3D dimensionality.

What are the differences between the two Ruhr models?

• Ruhr 18 uses a precise (2 x 5) number of solid pure copper conductors.
  This model is especially suited for use with integrated amplifiers, pre-amplifiers or sources.
• Ruhr 47 uses an optimized (2 x 13) number of solid pure copper conductors. Additionally it features our unique counter-spiraling design.
  This model is especially well suited for use with power amplifiers.
