It's fruitless to ask for measuring data standing for audiophile quality -- nobody can tell which measuring criteria cause which sonic characteristic. The same applies e.g. for amps. We're running in circles with such a discussion. Audiophile cables just are those which make the sound in your stereo setup (subjectively) better than standard cables.
Are there any "night and day" differences that would always and forever be beyond the capabilities of measurements?
And this is a serious and honest question......what are a couple of areas in which you feel audiophile cables consistently perform better?
