PranaWire Emerald-C Super Enhanced Ground Plane (Copper)

Audiophile Grounding Box


The PranaWire Emerald-C Super Enhanced Ground Plane (SEGP) is a larger version of the Ruby, with 4 binding posts and a copper Super Enhanced Ground Plane. The grounding box itself is made of Japanese Cedar and finished in a gloss clear coat.

Due to the delicate nature of the cedar wood, we recommend setting the Emerald Ground plane on Agora Acoustics MagicHexa feet to prevent the gorgeous finish from being damaged. A set of 4 MagicHexas are included with Every PranaWire Emerald.

As with all PranaWire Super Enhanced Ground Planes, you will enjoy greater stage depth, 3 dimensional resolution, specificity of instruments' location in space and vastly quieter background. The Emerald-C with it's 4 binding posts can accommodate up to 12 components. Systems hooked up to the Emerald-C ground plane exhibit their highest possible intrinsic capabilities with significant improvements in sound stage depth and width, palpability of instruments and musicians, their presence and location in space.

Chassis vs Signal - Digital vs. Analog

We recommend separating chassis ground from signal ground. Chassis ground is usually a safety ground for incoming power, and signal ground is for, well, the signal. Most high end audio components separate the two, so keep them separate when connecting to the Emerald.

The same goes for digital vs. analog components. Keep the grounds from these components separate from one another as well for best performance. 


  • Try on your wireless router connected to your audio system. 
  • Do not mix chassis ground with signal ground. Most high end audio components separate the chassis (AC) ground from the signal ground. Mixing the 2 on the Ruby Ground Plane will be a sonic step backwards.
  • Keep digital component grounds separate from Analog
