QED Reference XT40 X-Tube Spk Cable

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 cable fails to conduct uniformly across the entire conductor area. The result is that X-Tube delivers greater detail and fidelity across the audio spectrum which would other wise be lost in ordinary cables.
