[QUOTE="Cross_over, post: 1076817, member: 19846"] Interesting article, thanks. As someone who considers himself a subjectivist I do have to take issue with one statement: Other examples of the unreliability of testing to determine real sonic differences abound: Real and audible signal losses due to capacitive discharge effects in cables (remember that a cable not only has capacitance, but is, literally, a capacitor) can't be seen on an oscilloscope. As cancellation losses at the "zero" line, they're visible in a music signal only as reductions in peak-to-peak signal height, and are virtually impossible to determine. If losses were at the zero point the effect would be easily observed on a scope with a sine wave signal. Losses are amplitude related and not on the zero line, hence not necessarily audible. Capacitive effects of a cable may add a complex overlay to the "distortion" signature of such cable, however small the contribution might be. Cables also have resistance and inductance, they aren't purely capacitive. Sent from my SM-G960F using Tapatalk [/QUOTE]
