In Reply to: RE: I mean voltage, more precisely EMF posted by Presto on July 20, 2015 at 10:03:45:
Why would having low and high-pass filter currents in the same cable be less deleterious than having two separate, but in proximity, cables for low and high-pass filter currents? Aka, could not the low frequency content also modulate the high frequency content if in the same cable? In that case, the field associated with the lower frequencies is located immediately to the high frequency field.I don't believe the low frequency content in the cable can modulate the high frequency content in the cable. Modulation is a non-linear process. What non-linear property of the cable is there that could produce this modulation?
EDIT: Let me expand on this a bit. Suppose we could replace regular wire with some kind of non-linear semi-conducting material that did cause one frequency band to be modulated by another. Given that a full range voltage is applied to the cable by the amp, and thus a full range electric field is present in the cable, the modulation would occur regardless of whether or not there is induced EMF from the magnetic field of a nearby cable.
Regarding the basic question of how can single wiring be less deleterious, I would expect it's system dependent. The single and bi-wire circuits are different and not equivalent to each other, so it's plausible that with some systems and cables bi-wiring might make things sound worse.
