The guy from Harmonic has a white paper. This is an excerpt. Can anyone find a mistake? A big mistake.
"When copper slugs are forced through a small die hole to "draw" wire, the copper undergoes a molecular change due to the stress and rapid cool-down of the metal. A cross section of the wire seen through an electron microscope shows that thousands of crystals have been inadvertently formed in the copper. Approximately 500 crystal boundaries per foot are found in high grade oxygen-free copper, with as many as 1500 crystal boundaries occurring in normal wire. The barriers formed by the crystals become another impediment to the natural flow of electrons in the wire, adding harshness and brightness to the sound as well as changing the harmonic structure drastically, altering both image precision and sound stage focus. Indeed, the crystalline barriers add distortion to the signal, making their removal extremely important if clarity and smoothness are desired."
