I am not sure I would use your multimeter as indicative of the limits of scientific measurement. Depending on the length of the cable and how far you lift it, it could easily make 10s or 100s of pF difference. Completely irrelevant to the sound, but easily measurable by any decent capacitance meter.lindsayt said:Measurable with what equipment?andyjm said:In the spirit of balance, worth pointing out that suspending cables in free air will alter their capacitance from cable to ground, and any vibration on the cable will result in a change in resitance.
Both of these effects will be measurable, tiny and inaudible.
My digital multimeter wouldn't be able to measure it.
I'm not convinced it would be measurable, even with the finest measuring equipment.
It's the sort of thing where the slightest difference in the connection to the measuring terminals would make more difference than the cable lifting.
