The QED Reference XLR 40 cables build on the award winning Audio 40 range of products. XLR 40 was designed primarily for low capacitance as this has been identified by QED as a major factor which leads to a high fidelity experience. Further steps have been taken to eliminate minute timing errors in the cable by the use of a special floating Zn/Mn ferrite jacket alongside use of QEDs unique Tri-Conductor technology reducing signal to ground capacitance to vanishingly low levels.
