The Performance Audio 40i: Advanced sound quality with QED's complementary conductor technology™
The Performance Audio 40i represents the evolution of the already proven Audio 40 predecessor model. This cable sets new standards in terms of sound quality and value for money. Using the findings from the Genesis Report and integrating innovative technologies, in particular the use of solid complementary conductors, the Performance Audio 40i from QED achieves outstanding signal transmission properties.
Compared to its predecessor, the Performance Audio 40i is characterized by an even more pleasant and convincing sound reproduction. This is made possible by the specially developed conductor technology, which ensures optimized signal transmission. These improvements not only benefit the audio quality, but also offer an amazingly good price-performance ratio.
The Performance Audio 40i thus represents a new generation of audio cables that are both technologically advanced and offer an exceptional listening experience at an affordable price. With this cable, QED is setting a new standard in the world of audio connections.

Complementary conductor technology™: Innovation for precision and sound quality
Complementary Conductor Technology™ is an advanced innovation in the field of audio cables, characterized by the use of two solid, electrically insulated, oxygen-free copper conductors of different diameters. This technology is surrounded by a high quality structure consisting of a PVC jacket, a combination of foil and wire braid shielding, a ferrite jacket and a foamed polyethylene dielectric.
At the heart of this technology is the combination of a pure copper conductor and a silver-plated copper conductor. This special configuration ensures that the high-frequency components of the audio signal arrive at the same time as the lower frequencies. This results in an extremely detailed and three-dimensional sound reproduction that significantly enriches the listening experience.
A key component of this technology is the ferrite coating. This plays a decisive role in reducing signal loss and shielding against high-frequency interference signals. The sheath measurably improves the transmission quality, especially with regard to the precision of high-frequency pulses. As a result, these impulses are transmitted with fewer timing errors and increased dynamics, which leads to an overall improvement in sound quality.
In summary, Complementary Conductor Technology™ combines advanced materials and design principles to ensure optimal signal transmission while minimizing interference and signal loss. The result is an audio experience of exceptional clarity and dimension.
