It is interesting how Dynavector adopted the MC technology by paying license fees to Ortofon and possibly Grado, and when up and running, were producing its own patents which other Companies are adopting as their own versions, especially Ortofon.
It does suggest that a magnetic field interface that is controlled does have beneficial properties in how the end sound being produced is assessed.
It also suggests the designs are linear and quite predictable when control measures are undertaken with very tight tolerances.
