QED XT3 Mains Power Cable
If you're serious about your audio set-up and want to get the most out of your equipment, then the QED XT3 Mains Power Cable is an ideal option for you. Featuring a number of proprietary technologies, the XT3 cable is designed to reduce distortion and improve current flow in order to get the best sound out of your audio equipment. The XT3 is highly practical, being relatively thin and flexible compared to ordinary power cables. This makes it much easier to install and use in a range of settings.
In short, the QED XT3 Mains Power Cable is an ideal choice for those looking to get the most out of their audio set-up. With its combination of superior performance and practicality, it's well worth considering if you want to take your audio experience to the next level.
What QED say
QED is proud to introduce XT3 power cable, the latest in a new generation of audiophile power cables intended to complement its award-winning range of speaker cables and audio interconnects. Having introduced some of the very first specialist speaker cables and with over 47 years of unrivalled engineering excellence in the field of audio-visual connectivity, no other company can demonstrate such relentless dedication to research and development combined with analytical listening tests.
The new cord set features a number of proprietary technologies applied with regard to objective scientific research and subjective evaluation, to bring an audible improvement in performance.
As a result of X-Tube™ technology being applied to the XT3 power cable, fewer distortions caused by modulation of the impedance of the cable will affect current flow to audio equipment and so are less likely to find their way into the music.
Without a cable such as this to supply clean, noise-free current, many amplifiers can sound glassy and hard with less ability to respond to musical transients, giving a lack of dynamics and weak bass performance.
Finally, with the quality assurance of a fully typetested design, XT3 can be relied upon to safely bring audible improvements to audiophile source and amplification components alike.
X-Tube technology
QED XT3 power cables feature a specially adapted version of X-Tube™ Technology similar to that used in our speaker cables but specifically tuned to be appropriate for this new
application. The braided individual cores in the live and neutral conductors are made small enough that they are not affected by the eddy currents from adjacent cores which help contribute to the proximity effect.
Because they are effectively isolated from one another the carefully calculated twist rate of the strands means that no two conductors remain next to each other in the parallel configuration for more than a few millimetres, further enhancing the even current flow along the cable at all frequencies. The separate bundles are individually insulated using K130 PVC to control cable capacitance and provide the level of electrical isolation demanded by international safety standards, the whole arrangement is provided with a hollow LDPE core to control cable inductance. In this way the correct phase relationship between voltage and current is not altered by the cable parameters, further decreasing distortion when compared to an ordinary power cable.
Complete practicality
XT3 is designed to be as thin and flexible, and thus practical, as possible. Only the live and neutral cores have been given the X-Tube treatment described above - the earth core (required only under fault conditions) is left in a conventional geometry. And because X-Tube geometry enables the whole cross-sectional area of the cable to be kept to a tidy 1.5 mm sq, XT3 is supremely flexible and usefully slim despite its audiophile potential.
QED XT3 safety & type testing
There are many alternative brands of audiophile mains products on the market but even a cursory investigation reveals that many do not have the full set of required safety test reports and type testing certificates demanded by international legislation.
Rest assured, this is not the case with QED power cables. Because of the constraints which we placed on the design, the cordage fits into standard, high-quality plugs and connectors which fall into the parameters described by the harmonised standards.
In addition, the completed cord set including any additional overmould, covers and branded strain relief items added by us have been fully type tested to EN 60320, EN 60884 & EN 50525 by an accredited certification body and found to be fully compliant. Regular testing of the product at our production facility as set out in the annex to these standards is also carried out. A full test report is available on request from info@qed.co.uk.
Because mains plugs and connectors are not generally supplied as standard with gold plated pins, any that you might see for sale have usually been variously modified after manufacture by the reseller. This is not a good idea, as any type-testing certification which might be available for the product will have been invalidated by this process; effectively a new “type” has been created which is not the subject of the test report.

"From the off, the first few seconds, I could hear a real sense of control from the QED. Actual coherence around the music. The drop in noise, the stripping away of rubbish and sonic gunk, allowed me to actually hear the music instead of ‘music + rubbish’." "Across the broad soundstage, the QED succeeded in providing instrumental separation where none previously resided." The Audiophile Man - Product Review - November 2022

Free Cable Burn-In Service Option
We are pleased to offer FREE cable burn-in worth £50.00 on this cable for up to 96 hours, using our specialist cable burner.
The cable burn-in machine optimises the performance of the cables from day one. This means cables should be near optimum performance mode when you receive them, so you'll be able to make a performance assessment quickly rather than waiting 70 hours+ of usage. The results of conditioning cables are:
- improved sound staging
- increased detail
- overall more musical presentation.
Please select the 96 hour ‘burn-in option’ from the drop-down menu on the product page as this will fully optimise the cables.
Although it is not yet fully understood scientifically, the phenomenon of “cable break-in” has been experienced by many audiophiles. Interconnects, speaker cables and power cables seem to go through a conditioning period when used in an audio/video system and will sound better after many hours of in-system use.
The sonic differences between wiring that is broken-in and wiring that is not, are very audible in high-quality audio systems. The break-in process is believed to be due primarily to current flowing through the conductors of wiring components.
Dielectric stress caused by a voltage difference between the conductors is also believed to be of some benefit. The fact that it takes many hours of in-system use for wiring components to break in is primarily due to the low-level nature of audio/video signals from normal program material.
The cable conditioning machine was designed to produce signal levels far in excess of those seen in normal audio/video system use. Internally, the device contains a sweeping square wave oscillator that drives a very high-efficiency “H” bridge MOSFET switching circuit.
The signal levels produced by the cable conditioning machine are many times greater than that obtained under the most ideal of audio system conditions. The “stress” on the dielectric of the cable is also much higher than in normal use due to the higher output voltage. It should be readily apparent why results with the cable conditioning machine are often quite audible after as little as 24 hours of use.
