Cryo‐treatment
All IeGO power connectors have continuous cryogenic treatment by liquid nitrogen (−196 °C) for 20 hours. Cryogenic processing changes their metal microstructure at the molecular level. The crystal structure becomes smoother and more refined. The conductivity of the metal improves, which positively affects the signal transmission, and as a result — the sound. Changes in the structure of metal after cryogenic treatment are permanent and do not change over time.
Connectors with cryogenic treatment sound much better than their counterparts.
99.99% Furukawa Pure Copper for contacts
Unlike most of the other manufacturers, whose production of connectors uses brass or phosphor bronze with much lower conductivity, IeGO Power Dream Works uses only pure copper with advanced treatment to achieve maximum results of sound quality.
The material for IeGO connectors is the premium "red copper - 1020" — 99,99% of purity from the famous and reputable Japanese company Furukawa. Products from this copper sound better, thanks to the smaller sizes of crystals, which critically affect the signal transmission and loss in them.
At the factory, the perforation of pure copper sheets is done by computer stamping. During the process, the oxides are completely removed by etching. It’s followed by a washing process that removes residual liquid nitrogen. Pure copper achieves high resilience and meets stringent electrotechnical standards. At the last stage of production, contacts get ground and then polished to a shiny surface. Depending on the connector model, contacts are covered with a layer of gold, silver, or rhodium. At last, the plated contacts are polished again.
Housing material and other parts
To maximize the quality of its products, IeGO also pays special attention to other parts of connectors — housing material and fixing screws. The case of power connectors is made of special highest‐grade PC flame retardant Polycarbonate 940A with high specific gravity. Developed by the Japanese company “General”, it complies with the specifications of the UL standard E-45587 and has shock resistance, UV resistance, fire resistance, and a high degree of absorption of micro‐vibrations. The dielectric is the best, the capacitive reactance and impedance can reach the optimal sound performance.
The design of contacts allows clamping a cable by the whole surface with the aid of a special square buckle made of hard pure copper. The clamping screws are made of non-magnetic stainless steel and are color-coded.
