“Cables: Most all cable manufacturers agree that break-in is a result of changes in the conductor and/or dielectric. According to one manufacturer: "The insulation (or dielectric) will absorb energy from the conductor when a current is flowing (i.e. when music is playing). This energy-absorption causes the dielectric’s molecules to re-arrange themselves from a random order into a uniform order. When the molecules have been rearranged, the dielectric will absorb less energy & consequently cause less distortion."
Cardas has, for years, included a Cable Break-in Guide with their cables. In it they state: "All cables need a break-in and warm-up period. Better cables require longer break-in. With all cables, the more you play them and the less you move them, the better they will sound." The unique geometry of Cardas cables require that "...the strands be of equal tension... Current flowing through the cable during break-in, and each warm-up period, will relax the structure of the strands."
Another prominent cable designer believes that during the break-in process electrons are establishing new micro pathways through the conductor material. changes in the conductor is the primary reason for the improvement realized through break-in. They believe that most of the signal travels across the surface of the conductor. Viewed under a microscope the surface that appears smooth to the naked eye is really a series of peaks and valleys. The irregular surface forces electrons along a circuitous path to their destination. When a cable is bent or twisted, new tears and fissures form, disrupting existing pathways and requiring new ones to be formed. This explanation lends credence to reports that cables need to be re-conditioned (after) being handled. I’ve seen this in a very real way.”
