KOJO TECHNOLOGY Crystal Ep-G Series Plug-Type Ground Box (Made in Japan)

The KOJO Technology Crystal Ep-G Series is an ultra‑compact, plug‑type ground box designed to dramatically increase effective grounding surface area, reduce noise, and enhance clarity, detail, and stability in your audio system. Simply plug it into an unused terminal to enjoy a cleaner background and more natural, open sound.

Key Features

  • Flagship dual-layer capacitor array: Uses “super-capacitor” style dual-layer capacitors arranged in a radial cylindrical structure to provide an enormous 10,000,000 cm² of grounding surface area.
  • Porous activated carbon electrodes: Multi‑porous activated carbon electrodes combined with high‑purity aluminum foil create an ultra‑large effective surface area, far exceeding that of conventional aluminum electrolytic capacitors.
  • 900× grounding area vs. Crystal Ep: Delivers roughly 900 times the grounding surface area of the entry‑level Crystal Ep for significantly stronger noise absorption and stability.
  • Brass housing: Heavy brass body suppresses vibration and external interference, further improving resolution and focus.
  • Ultra‑compact design: Plug‑type ground box fits directly into unused input/connector ports, ideal for crowded racks or desktop systems.
  • 10 interchangeable plug types: Wide plug lineup covers common audio interfaces, and the plug section can be swapped to match different devices and connection needs.
  • System expandability: Can be used standalone or daisy‑chained with other Ep series products and Crystal E series ground boxes for system‑wide grounding enhancement.
  • Made in Aomori, Japan: Designed and manufactured in Japan to KOJO’s exacting standards.
