Very little original research has been carried out relative to diamagnetic materials and temperature. Most of it is specific to ferrous metals, working strength, structure and so on. The research that has taken place in the super low temp work relative to diamagnetic metals and E&M behavior at these temps is nearly exclusively for super conductive work—coopers pairs, tunneling, zero resistance—not so much hi-fi. Some hi-fi guys love chillin’ their cables, some even their drives, cartridges, CDs, and LPs. We have done a fair bit of testing, using a very long rates of change and the results so far have not been conclusive, except on magnetics, like hard disk drives, speaker drivers and phonograph pickups—not favorable, don’t do it.
