About The QED Silver Anniversary XT Speaker Cable
QED's multi-award winning Reference Silver Anniversary XT speaker cable delivers superior performance for all your hi-fi and home theatre speaker wire needs. Buy as much as you need, but remember that plugs/connectors are not included.
Part of QED's Reference Range, Silver Anniversary XT has been specifically designed as the natural replacement for the multi-award winning Silver Anniversary speaker cable. Combining the features of Silver Anniversary with the added enhancement of X-Tube technology to combat the skin effect and deliver stunning detail. High performance low density polyethylene dielectric cuts down on the amount of audio signal energy lost due to cable capacitance. Silver plated 99.999% OFC conductors provides a low frequency path for the audio signal and delivers stunning high frequency detail.
QED X-Tube Technology: At low frequencies both X-Tube and conventional stranded/solid core speaker cables convey signals in a linear way. However, at high frequencies, X-Tube 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-Tube with polycore technology exhibits much lower self-inductance and is therefore less affected by this problem. The polycore technology reduces loop inductance too levels only achievable using more costly and difficult to terminate cables. So, with more high frequency detail, less distortion and greater performance, X-Tube delivers greater fidelity across the audio spectrum which would otherwise be lost in ordinary cables.
Awards
What Hi-Fi? awarded the QED Silver Anniversary XT 'Product of the Year' 3 years running and had this to say about this remarkable cable: "nothing else at this price point sounds as superbly balanced and detailed".
The History Of QED
In 1973 Bob Abraham and Ian Vine founded QED Audio Products and changed the way people think about hi-fi cables. By the time QED 79 strand was launched in 1978, it wasn't considered' just another speaker cable' but a serious hi-fi component. During 1994 QED conducted the most extensive ever scientific investigation into the effects of speaker cable on hi-fi system performance. Read the results in "The Genesis Report". Hear the results whenever you listen to your favourite music using QED 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 speaker cables are recommended by so many of the world's leading manufacturers of hi-fi and home theatre equipment. QED is Europe's number one award winning connectivity brand and has won more prestigious cable awards from 'What Hi-Fi? Sound & Vision' magazine than any other brand (Awards 1981–2013). - QED - The Sound Of Science
