The Kryo Banana Connector – Silver Plated Copper | ETI Research features a silver-plated Tellurium copper conductor, a reinforcing copper pillar, and a larger 5mm cable insert matching the Kryo Spade.
The Kryo Banana is ETI Research’s silver-plated banana plug connector, built around a Tellurium copper conductor for maximum signal transfer. The silver-plated finish is applied directly to the copper, with no nickel plating anywhere in the connector — nickel is known to degrade sound quality, so leaving it out keeps the signal path clean and the conductivity high.
At the tip, a dedicated copper pillar now reinforces the banana connection point. Rather than a single solid piece of copper, the conductor and pillar work together to add mechanical strength exactly where the connector meets the binding post, without adding extra resistance or capacitance into the signal path.
The cable insert has been increased to 5mm, now matching the Kryo Spade, making it easier to terminate thicker cables securely and giving a firmer grip once installed.
Each connector is housed in matte black brass for outstanding shielding, mitigating unwanted electromagnetic interference (EMI) and radio frequency interference (RFI). Left and right channels are marked with colored enamel rings for quick identification. A double strain relief system — twin screws inside the connector chamber plus a second set securing the brass housing to the cable’s insulation — clamps the bare wire and housing without any soldering, keeping installation fast and the connection mechanically solid.
