"Detail resolution is wonderful: the XT400 reveals the finer points of complex tunes. This is a truly accomplished cable." What Hi-Fi Sound & Vision magazine.

Featuring 99.999% oxygen free, silver plated conductors, the QED X-Tube XT400 is constructed from the finest materials. Yet it's the Aircore dielectric that makes this speaker cable truly unique and one that, once listened to, you won't want to give back!

To maximise the potential of this cable we recommend that QED Airloc plugs are fitted. Please visit your nearest store for details of fitment.
Rated 5 out of 5 by from Best upgrade I've done Although I have a very good system there was something missing at the top end. Not any more all there now and at 20 a metre it's the biggest bang for buck upgrade you could do. So after all the arguments I've read online the best speaker cable really does make a big difference.

Rated 5 out of 5 by from A lovely sounding cable. I've been using this cable for years and just purchased a second system of Marantz Ruby & Kef R3. Extremely happy with the cable after a demo with a few others, I decided to buy more of the same.
