XT Golden Anniversary

QED celebrates 50 years with special edition speaker cable

QED is celebrating its 50th anniversary in style, with the introduction of its Golden Anniversary XT speaker cable. Representing the culmination of five decades of dedicated and in-depth research, engineering and audio expertise, the Golden Anniversary XT speaker cable is the ideal upgrade for any hi-fi enthusiast who wants to experience the sonic benefits of a high-end speaker cable, but at an affordable price. real world price

Five Decades of Audio Engineering Pedigree

QED has been designing and manufacturing class-leading, award-winning analogue and digital cables for fifty years and the Golden Anniversary XT is the latest demonstration of the company’s expertise.

Quality Electronic Design (QED) was founded in 1973 by forward-thinking hi-fi enthusiasts Bob Abraham and Ian Vine. The company is now considered the original cable brand, having released the QED 79 Strand, widely regarded as the world’s first ‘specialist’ speaker cable. This product demonstrated how cables could have a tangible impact on audio performance.

QED’s Genesis report on loudspeaker cable design followed. This research established scientifically proven principles that are as valid today as they were 28 years ago and inform all QED cable designs, including the pioneering X-Tube™ technology that enables precise and consistent signal transmission across the entire frequency range.

The main features in brief

NEW X-Tube™ Plus technology combines X-Tube™ with Aircore™ to deliver smooth, consistent performance across the entire audible frequency range.
The blend of ultra-pure Ohno continuous-fused copper conductors and 99.999% oxygen-free copper helps improve signal path and signal retention.
Ultra-uniform low-loss dielectric isolation increases efficiency and reduces signal loss.
Airloc™ Forte banana connectors use a cold welding system to permanently attach to the cable for improved contact area and reduced resistance.
X-Tube™ Plus Technology

QED’s innovative and proven X-Tube™ technology places the conductive material of a cable around a central hollow insulating rod, resulting in the elimination of the skin effect that would otherwise force high frequency analogue music signals out of the conductor. Furthermore, by combining X-Tube™ technology with its equally effective Aircore™ technology, QED also reduces the proximity effect that can disrupt the current distribution in a speaker cable. The result is X-Tube™ Plus: an innovative cable geometry that ensures Golden Anniversary XT is a speaker cable with smooth and consistent performance across the entire audible frequency range.
Ohno ultra-pure continuous fusion copper conductors

Golden Anniversary XT uses a unique hybrid blend of 99.999% Oxygen-Free Copper (“OFC”) and Ohno Ultra-Pure Continuous Fused Copper (“UP-OCC”) to deliver the improved signal path and exceptional signal retention of ultra-pure copper conductors – but at a fraction of the price. With class-leading research and engineering, QED Golden Anniversary XT is the most affordable and affordable speaker cable to harness the benefits of the continuous fused process, with this hybrid theoretically enhancing the path of transients and high-frequency detail not available using OFC alone.
Ultra-uniform low-loss dielectric insulation

If you want a speaker cable to perform to its full potential, it is important that the dielectric material that insulates and protects the cable’s center conductors does so efficiently. Golden Anniversary XT uses a specially developed and formulated Low Density Polyethylene (“LDPE”), which works in unison with the cable’s X-Tube Plus configuration to provide a highly efficient speaker cable with a barely measurable dissipation factor.
Airloc™ Forté Banana Plugs

Airloc™ is a specially developed cold solder system to permanently connect QED Forté banana plugs to the company’s entire range of speaker cables, including Golden Anniversary XT. The most vulnerable area in the speaker cable chain is the physical interface between the cable and the speaker or amplifier it is connected to: without effective termination, oxidation can occur, reducing the performance of the cable. By using a cold solder crimp-type termination, Forté banana plugs offer the ultimate resistance to oxidation – for the life of the cable – effectively turning the cable and plug into one unified object.
