Kojo Technology Crystal Ep Series Ground Terminals

These terminals act as a virtual ground, utilizing high-purity aluminum foil to significantly increase the conductor surface area. By effectively managing electrical noise, they help lower the noise floor, resulting in improved clarity and detail in your audio playback.

The correct choice depends on the available ports on your specific audio components. You should select the plug type—RCA, Banana, 3.5mm Stereo Mini, or Spade—that matches an unused input or output terminal on your amplifier, DAC, or speaker system.

Yes, these are compatible with most audio components that feature standard RCA, Banana, 3.5mm, or Spade connections. Because they are plug-type devices, they are designed for easy installation into any open port on your equipment.

No, the Crystal Ep series is a self-contained virtual grounding solution. It does not require a physical connection to an earth ground, as it uses its internal surface area to manage noise internally.

Yes, the sandblasted pear-finish on the body and cap is not just for aesthetics. It increases the effective surface area of the metal, which contributes to the device's overall performance in noise reduction.

You can start with a single unit to test the impact on your system, though many audiophiles choose to add them to multiple components, such as both the left and right channels of an amplifier or a DAC, for a more comprehensive effect.
