So why is the audio field so lousy about basic measurements such as power handling characteristics of cords..@edstrelow I know someone working with power distribution and they have very expensive measuring equiptment for checking a lot of things. The cost may stop us somewhat. You want to see if a cord affects the current/power in your home when your system is connected to it. Their end game is also a bit different than highend audio, they want to find some problems to fix them and save money (or just check that the system works) and they work with much, much higher currents and voltages.
Of course the sellers could get better at measuring things and showing that measurements for us consumers. Like: "Given this type of disturbances on your power line our cable lowers the disturbances this much".
