Shunyata Sigma Analogue ETron Power Cable
We now have this cable on the floor. The Sigma line is the top of the Shunyata line and everyone is saying they have made another notable advancement in the art of power delivery. This cable has the ETron noise circuits built into the new CopperCONN connectors stopping noise before it migrates to the component or back into your power conditioner. These connectors are also newly designed and made from telluriuum copper with a thin protective coating.
As before cyrogenic treatment is part of the Shunyata process.
