ETI Research Kryo RCA (pair)


The combination of high-quality materials and precision manufacturing add up to a superior RCA connector, to enhance any audio cable range by allowing the signal to pass through with minimum alteration.

ETI Research Kryo RCA Connectors utilise the same design as the Brio range of RCA connectors, but with Silver Plating instead of Rhodium. A Tellurium Copper and Silver combination is a hallmark of the entire Kryo line, as is of course a stringent cryogenic treatment process to ensure absolute quality and material strength over time.


ETI Research employs the Silver Plating process as Silver’s electrical resistance is lower than Copper; more so at higher frequencies due to the skin effect. And of course, when properly implemented, it’s difficult to find a superior method for audio throughput than Silver Plating of Tellurium Copper.


The ETI Research Kryo RCA Connector’s innovations and refinements include:

  • Major components made from Tellurium Copper with Silver Plating for superior conductivity and long-lasting durability.
  • Housings made from Brass for superior vibration damping and high EMI/RF noise rejection.
