The QED Performance Audio 40i Phono Pair builds on the strengths of the original Performance Audio 40 and delivers an even more enjoyable and convincing sound – without affecting its prodigious value for money.
Using the principles laid down in its industry-defining Genesis Report, as well as some startlingly original technology (including the ground-breaking Solid Complementary Conductors), QED has created an interconnect that puts as much distance between itself and its nominal competition as the original Performance Audio 40 did over six years ago.
Solid Complementary Conductor technology
Beneath the PVC jacket, braided foil shield, ferrite jacket and foamed polyethylene dielectric are two solid, electrically isolated and Oxygen-free copper conductors of different diameters. Using two wholly separate conductors (one copper and one silver-plated) to carry the overall audio signal provides the most complete, least compromised route for audio information to travel.
The resulting sound of the Performance 40i Phono enjoys greater scale and three-dimensionality than has been previously achievable from an interconnect of this price, helping QED maintain both its reputation as an innovator and a class leader.
Ferrite jacket
The ferrite insulation delivers measurable improvements to both the amount of high-frequency signal noise rejected by the Performance 40i Phono Pair and the amount of relevant signal information lost. The improved accuracy of high-frequency impulse transmission impacts positively on timing, and on dynamics both broad and low-level.
Just listen
The QED Performance 40i has numerous technological highlights, and weโre convinced it represents amazing value for money. The easiest way for you to understand what we mean is to hear it in action for yourself.
