Ditto here, At Bruel and Kjaer I can measure the difference in signal with any signal, even music at either end of a cable - loaded by only a cable to a non-coherent power level of down to over -120dB below the signal level (given that I can repeat the signal many times...) Non-coherent power is the measure of the amount of signal at the output that does not match the input. The only limitation in my measurement system is its 25.6KHz aliasing filters. Most cables or speaker wires exhibit levels indistinguishable from the measurement noise floor. ie, NO DISTORTION. The same measuremet will yield a frequency response of the cable and the only variations with typical cables are within 0.02 dB - except for cables with noticeably "odd" construction.
