Do I need 10 gauge power cord if I have 10 gauge from panel?

@jasonbourne52 … “Do you really believe that you can hear a difference between the Hurricane vs. the Thunder? A degreed electrical engineer will tell you otherwise! ”

I can hear the difference between a 1 meter and 2 meter Hurricane… as well as all the other power cords I own.

I came up with my own sonic rating scale years ago, but more recently found this one. It helps to systematically evaluate sound quality changes.

Also, you cannot honestly speak for all electrical engineers. I have know hundreds. I can say that most of those that actually sit down and listen to a good system will hear the difference… those just asked may say that is impossible.

I removed the chart from my last post that showed  some dimensions to judge the sound of audio cables. It was not mine and I did not have the authors name to attribute it to, so here are some of the dimensions.

Soundstage, imaging, bass speed, bass,  wait, bass extension, lower range, mid range warmth, upper mid-range presents, upper mid-range refinement, transient attack, mid range body, decay, high frequency extension, sibilance control, tonal accuracy. Rate each on one to 10 scale.

To make it easy I rated everything the best I could doing it very carefully and make it easy as I said the total came to an average of 7.6.

Is that helpful?

I think Nelson Pass said this although not sure it was his quote originally: "Some of what we can hear cannot be measured & some of what we can measure cannot be heard". Sound reproduction is not an exact science because there are simply too many factors involved, especially the unpredictable interactions / compatibility between various system's components. 

Just listen & see what you enjoy the most. It doesn't matter what anyone thinks or says.
