I'm having a really hard time with: "Power cable reduced my soundstage"...

I just paid 60ish dollars for a 10 ga. 50 ft. Power cable for my RV... I’m not sure so please correct me that the rv’s a/c and other systems pull more juice than a A 21 running at listening volumes. 10 ga. Is a big cable.

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".

Seeing as this tread has  deteriorated again into questions about the last four feet,  
Voodoo and the like, I have a question.
Does anyone just unplug their systems when the weather person says severe and storms in the same sentence? 

Just curious.

Over the years I've upgraded interconnects, speaker cables and power cords. (Mostly Cardas at this point). To my ears, the power cords have been the hardest to hear differences. Lower noise floor, a bit smoother highs. 

years ago I was helping my electrician rewire an old building. I was drilling holes though basement joists that were about 2 inches thick as I recall. The drill I was using was on a 100 foot extension cord and was laboring to get through the joist. My electrician told me to use a heavier cord. Upon getting a heavier cord ( maybe 10 gauge) the drill stopped laboring. That was an early lesson in not restricting power. Joe
