When there is an audible difference in speaker wire due to wire capacitance, it can be interpreted as an improvement when one wire appears to have more clarity but is actually altering the sound and departing from accuracy. Perhaps this change in sound then paves the way to sell more wire. Further, perhaps the wire companies already know this and what will sell. If the speaker wire companies had not introduced wire having high capacitance, either out of ignorance or by intention, then there would have been no controversy like this and ordinary low resistance wire, which incidentally has very low capacitance, would have remained king from the beginning.
