If your speakers are designed for bi-wiring, but are only connected to your amplifier by single cable runs, then a very cost effective way of upgrading your sound system would be to invest in a set of QED XT40i speaker jumper links.
QED Reference XT40i speaker jumper links are supplied fully terminated with AIRLOC gold-plated banana plugs and standard (non-Airloc) spade terminal connectors for optimum sonic performance at an affordable price. Heatshrink is used to insulate and complete termination of the links.
QED Reference XT40i jumper links on offer are a stereo pair:
4 cables in total (one pair each +ve and -ve polarity designated links).
QED XT40i pure copper speaker cable uses an evolution of QED’s established X-Tube technology to guarantee superb timing and stereo imaging, bringing superb rhythmic accuracy and musicality to a cable of this modest price. Very low DC resistance adds unrivalled frequency response to XT40i’s already potent audio capability. The result is a cable that advances on the class-leading standards set by its predecessor.
Air Gap Dielectric
QED have added a brand new and highly innovative low-loss Air Gap dielectric to the cable by increasing the separation of its conductors and therefore the amount of air between them. This technology halves the dissipation and capacitance characteristics of the cable, resulting in numerous audible improvements - particularly where timing and rhythmic accuracy are concerned. Despite this increased separation, XT40i retains the sort of cross-sectional area that makes it ideal for long cable runs.
Large Cross-Sectional Area
The 4mm2 cross sectional area means XT40i exhibits very low resistance, allowing amplifiers to exert outstanding control over the speakers they are driving. In addition, its large cross sectional area makes it suitable for long cable runs.
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-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. 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 a cable with more high frequency detail, less distortion and greater performance.
