Overall tonal balance of SQI series cables is exceptional, with solidly defined bass response and crystal clear highs. Extremely small diameter strands of oxygen-free high conductivity copper is utilized on both the center conductor and shield to provide the best audio path possible. Low capacitance insulation material is used improving overall fidelity. The 95% coverage shield assures you that the signal will remain intact in adverse conditions. The outer jacket of the wire is a special formulation of PVC compounds which provide exceptional flexibility and durability, as well as protection against the handling noise often encountered in lesser cables.
