QED X-Tube XT-400 Jumper Cables (1 Pair)
QED's multi award winning XT400 Speaker cable, utilising X-Tube™ Technology Silver-plated oxygen-free copper tubular conductor geometry.
For use in the finest hi-fi and home theatre systems. This design delivers a massive cross-sectional area using X-TubeTM technology to eliminate the skin effect whilst maintaining a user friendly “figure of 8” geometry. This is QED’s ultimate affordable upgrade for high end systems.
Silver Plated 99.999% Oxygen Free Copper Conductors
Provides a low frequency path for the audio signal and delivers stunning high frequency detail
 |
X-Tube™ TechnologyAt low frequencies both X-Tube™ and conventional stranded/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-TubeTM retains a near-linear signal transfer, whereas the conventional cables fail to conduct uniformly across the entire conductor area. In standard speaker cables at high frequencies current flow is highest at the periphery with rapidly deteriorating current density towards the centre of the conductor. The effect of this is to reduce the actual cross sectional area of the cable at 15kHz to less than 75% of that at low frequencies. This results in higher distortion and compromises the performance of the cable. X-TubeTM with polycore technology exhibits much lower self-inductance and is therefore less affected by this problem. The polycore technology reduces loop inductance to levels only achievable using more costly and difficult to terminate cables. The result is more high frequency detail, less distortion and greater performance. |

Termination
This cable is professionally terminated by Futureshop's expert engineers using QED's superb 24 Carat gold plated AIRLOC termination plugs.
AIRLOC is QED's specialised loudspeaker termination method and offers the very best termination with QED speaker cables. This is a solder-free, airtight fusion between the cable and plug offering optimum signal transfer, excellent signal quality and perfect long-term performance.
QED’s AIRLOC FORTE metal banana and spade plugs deliver a superior performance over many plugs offered by rival manufacturers for the following reasons. Firstly, the plug is crimped around the conductors under high pressure using a special tool supplied by QED. No soldering is used and as a result the conductors are in contact with the plug 360 degrees which maximises the surface area contact. Furthermore, the banana plug itself is in contact with the binding post again at 360 degrees. The net effect of this is it maximises the signal transfer from the plug into your equipment and hence a superior performance. When bare wire is used not all the conductors are in contact with the binding post and as a result some loss occurs.
Unfortunately the metal barrels for the AIRLOC spades were discontinued in 2012 however we still use genuine QED’s AIRLOC spade plugs with genuine QED heat shrinks over the spade plugs. This ensures every QED speaker cable comes fully terminated with the best of QED's engineering.

By the time QED 79 strand speaker cable was launched in 1978, it wasn’t looked upon as ‘just another speaker cable’ but was instead regarded as a serious hi-fi component, making a fundamental change in the way people thought about cables.
QED's reputation for innovation and technical excellence is known throughout the world. The latest computer-aided design techniques allow their research and development team to keep pace with technological advances and deliver products that achieve the highest levels of performance and reliability. This is why QED products are recommended by so many of the world’s leading hi-fi and home theatre equipment manufacturers.

Response from Future Shop

Thank you for your review.
Upon reviewing your feedback, we consulted with our engineering team for clarification. It appears there's been a misunderstanding regarding the banana and spade plugs. According to our product specifications, the banana plugs should indeed come with the barrel, as depicted on our product page. However, the spade plugs are equipped with heat shrink, not the banana plugs.
To clarify, as mentioned on our product page: Since 2012, the metal barrels for the AIRLOC spade plugs were phased out. Nonetheless, we continue to employ authentic QED AIRLOC spade plugs, which are now coupled with genuine QED heat shrinks. This adaptation ensures that every QED speaker cable remains fully terminated with QED's premier engineering standards.
If your product did not include the barrels on the banana plugs as expected, please contact us directly at sales@futureshop.co.uk. We're here to assist and ensure your product meets the advertised specifications.
Good product and excellent service.

Good product and excellent service. These jumpers have replaced the metal connectors on my McIntosh power amplifiers with very good results.
Future Shop's sales department is unbeatable.

Well built cable, much better than the original link bars

I wanted jumper leads to replace the link bars on my ATC SCM 40 speakers. I use a QED XT400 speaker cable on them, so it made sense to use the same cable.
The ATCs have six binding posts in a tight housing. It was not easy to set up, but with help from Future Shop, it worked and sounds excellent.
I recommend the cables and good customer service from Future Shop.

Bought the jumper cables to replace the factory fitted metal links on my new A.T.C scm40 loudspeakers.
The build quality of these cables are superb and complement my main qed xt400 cable very well ❗ I've orders several products from this company and every time the service I receive is fantastic ,.from how quick I receive the products to the way they are terminated,to the way they are packaged ❗ all in all fantastic company and fantastic products and service.

The XT-400 jumpers mated well with my Atlas bi-wire set which add more life to the higher frequencies and my Cardias Gold Reference which focus on bass, midrange and sound stage.
The recordings I love opened up with detail and space but also displayed any older/cheaper recording short comings. I could have chosen much more expensive jumpers but I feel happy with my choice.
