Power cable Advice...

I have not been impressed with Audio Quest in the past. But the Storm generation is a completely different story and a breakthrough. It does not shift the tonal balance, it dramatically drops the noise floor, without imparting a sonic signature, so more dynamic and quiet. The Hurricane and Dragon have been the buzz of the industry the last couple years for good reason. 
 

I suspect there are at least two innovations… the battery thing and the plugs on each end are really tight… I mean really tight. You’ll have to hold the front end of your fifty pound or heavier amp so not to move it when plugging in. 
 

The Hurricane on my power amp quickly brought my year long search for the right power cord to an end. 

I suppose I’m just a novice, but what exactly does a $5000 power cord do for the electricity. 🤷🏻‍♂️

Makes it sound better. 

Audioquest Thunder and up the Audioquest line from there.  I have two different brands of PCs in my system (Audioquest and JPS Labs).  I have JPS Labs speaker cables and Audioquest interconnects.  They all work together to create pure magic.

A more serious answer. 
 

This is a video of an interview with the founder of Shunyata. At about 10 - 11 minutes he starts going over what a power grid is and does. This should help.
