ETI Research Kryo Spade Connectors

The ETI Research Kryo Spade Connector is designed for high-performance loudspeaker connections where conductivity, mechanical security and effective noise rejection are important. Manufactured from premium conductive materials and housed within a matte black brass casing, it combines a low-resistance signal path with practical cable termination for audiophile, studio and professional audio applications.

The ETI Research Kryo Spade is manufactured from a single solid piece of Tellurium Copper, providing high conductivity together with the mechanical strength required for long-term use. Silver plating is applied without an intermediate nickel layer, maintaining a direct conductive path while providing a durable contact surface for repeated connection and disconnection.

A matte black brass casing surrounds the conductive assembly of the ETI Research Kryo Spade, providing shielding against electromagnetic interference and radio-frequency interference. This helps protect the audio signal from external noise while also giving the connector additional mechanical protection. Colour-coded enamel rings identify left and right channels, simplifying installation and system setup.

Cable termination is handled by a double strain relief system using twin screws. These secure both the bare conductor and cable insulation, eliminating the need for soldering while helping reduce mechanical stress on the connection. Combining Tellurium Copper, silver plating, brass shielding and secure screw termination, the ETI Research Kryo Spade Connector is suited to critical listening systems, studio installations and live sound applications.
