The Performance Audio 40i builds on the strengths of the original Performance Audio 40, offering an even more enjoyable and convincing sound without compromising its excellent value for money. By utilizing the principles defined in the innovative Genesis Report, as well as some remarkably original technologies (including the revolutionary Solid Complementary Conductors), QED has created an interconnect cable that moves away from the perceived competition as far as the original Performance Audio 40 did six years ago.
