Monitor power cables are using stranded copper of 99,9997% purity for the Live and Neutral conductors and a stranded OFC of slightly larger cross sectional area for the Ground conductor.
The twisted design, the proper grounding and the increased purity of their conductors, provide an effective rejection of electromagnetic and radio frequency interferences and in the same time improve the sonic performance of electronic devices, helping them reproduce music with enhanced detail, deep bass and impressive clarity.
