The QED Performance Audio 40i is a high-quality analogue interconnect designed to deliver clear and accurate audio between hi-fi components such as CD players, DACs, streamers and amplifiers. Using QED’s Solid Complementary Conductor™ technology, the cable features two electrically isolated conductors of different diameters to carry the same audio signal, helping preserve detail and improve timing across the full audio frequency range. Constructed with 99.999% oxygen-free copper and silver-plated oxygen-free copper conductors, along with a low-loss foamed polyethylene dielectric, the cable maintains excellent signal integrity while reducing capacitance and interference. Precision RCA connectors provide a secure, low-resistance connection, making the Performance Audio 40i an ideal upgrade for hi-fi systems seeking improved clarity, dynamics and overall musical performance.
