Quite so.
However, I've just invented a polarising magnetometer, which helps to re-orient the magnetic field throughput that all speaker cables generate. Of course, as is well known (by me), magnetic field anomalies add unwanted noise and colourisation to any transported signal - adding significantly to interference at the speaker end. My polarising magnetometer (or PolarMag, to give it its' scientific/sales name) helps to re-order these fields, ensuring that the electrical signal travelling down the speaker cable travels along the path of least resistance, and thus reduces colourisation.
To gain the maximum benefit from the PolarMag, I suggest you place them at 1m intervals along the length of your speaker cables, and having done that, sit back and revel in the improvements in clarity, purity, national balance of payments and world peace consequently generated!!!
