40 Years Of Cable Perfection

40 Years Of Cable Perfection

QED are celebrating 40 years of British cable excellence with the release of three outstanding cables that correspond with QED's long-established 'good-better-best' philosophy. QED's Performance, Reference and Signature Audio 40 analogue cables all share the exact same geometry and construction patterns but with increasingly high quality materials in each cable. Performance represents a cost-effective alternative, Reference strikes the perfect balance of performance vs diminishing returns and Signature proudly represents the ideal 'cost no object' approach.


"QED have updated its four-star Ruby Anniversary cable to great effect. The way the QED communicates dynamics is particularly entertaining, too. It’s revealing, agile and offers a really open performance. A great cable"

QED's celebration at 40 years of being the pioneers in audio and connectivity has extended itself to the Ruby Anniversary Evolution speaker cable, an improved tweaking of the excellent Ruby Anniversary cable. 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.

We can supply this cable cut to any length you require or you may select from the menu to have your cable terminated with a selection of banana plugs or spades professionally.
