S/G Ratio: The Golden Ratio for signal transmission is ETI’s patented Signal/Ground or S/G Ratio Formulated from listening experience and physics fundamentals the S/G Ratio is applied to many aspects of the cables’ conductivity to optimize the electron flow. Key to its implementation are the deliberate differences, physical and electrical, between a cable’s signal and ground conductors. Most famously applied to the solid copper cores of cables, research into the S/G Ratio was extended and is now applied to the unique wires used in the eXpress CU and eXpress HB range. When implemented successfully audio system performance is appreciably better. Increased detail and smooth reproduction deliver a high end presentation that good music deserves.
