XT3 Power Cable

The groundbreaking XT3 Power Cable analogue audio interconnect celebrates QED's 40 years at the forefront of British designed audio cables

XT3 Power Cable is an entirely new design concept from QED laboratories. The cordage is designed primarily for low capacitance as this has been identified by QED as a significant factor leading to a high-fidelity experience and makes for a tight sound retaining the rhythm of the original piece. Add our Complementary Conductor Technology™ for high frequency detail and our Analoc2™ technology to maximise signal integrity and the result is what we feel to be the most innovative interconnect ever made by QED. Please see our 'cables matter' section below for more in-depth information on this groundbreaking design.

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.

ecause 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.

Give your audio equipment clean, stable current and let it perform to its maximum.By adapting the X-TubeTM technology it developed for its award-winning ranges of speaker cables to the specific requirements of mains cables, QED effectively regulates mains current flow, with results that are obvious when you listen.

"...the improvements over the basic, default kettle-type cable are real and impressive. If you run such cabling on your HiFi then please consider an upgrade for each component sullied with the dratted things. And if you decide to go with the XT3 as a source of sonic solace then your hifi and your ears will thank you for it. "
