Five-Star award winner QED Ruby Anniversary Evolution cable
An all-new speaker cable from QED labs celebrating 40 years at the forefront of UK speaker cable design. QED “Aircore Technology ™” in a new miniature format to bring high-end cable philosophies to the Budget Hi-Fi market is using. It builds on the success of XT Evolution and Ruby Anniversary cables with which it shares a family legacy, but now includes increased conductor spacing to further reduce losses and distortions caused by cable capacitance.
Uses conductors of different diameters to carry the same audio signal.
This provides an alternative path for high-frequency audio components that might otherwise become time driven in a single vocal tract. Over 2.5 mm² of cross-sectional area, QED cables use air core technology to eliminate the skin effect by combining several individually insulated small cores to form a larger CSA. If these conductors are passed through a polyethylene consisting of a hollow center, the self-inductance exhibited by the cable can be reduced to about half that estimated by calculation.
