In this recent upgrade, the Aircore™ technology utilised on the Audio40 analogue interconnects has been carried over in a new miniature format. Ruby Anniversary Evolution has a fairly conventional figure of eight form on the outside but within this clear polyethylene outer ten 99.999% OFC conductor cores wrap around an inner hollow core. Using this design "skin effect" is reduced which results in a wider frequency range using more of the available conductor. The individual copper strands are visible through the jacket, giving this cable its unique look. Ruby Anniversary combines high-end cable technologies with a reasonable price point which makes it ideal for mid to high end hi-fi and home theatre applications. We highly recommend this cable as a step up from regular copper or budget wires.
