Best DIY power cable. Why not make?


Ok perhaps I don't get it.  You have hot, neutral, ground and connectors.  I am looking for advise from those that have found the secret sauce in making power cables or at least those that have had great success.  With all the quality cable and connectors why not make your own?  I refuse to pay $2,000 plus for a power cable that would take a hour to build.  I am seeking your guidance and suggestions.  Thanks!

The benefits would be patently obvious. My integrated is dead quiet with any power cord I've tried but it's the sound that comes out of my speakers that's different.

Soundstage, more relaxed or forward? More depth? What discernible atributes of the sound? I thought the only benefits would be noise floor. I’m speaking out of ignorance, I don’t know what the benefits would be.

Exactly, experimenting is the only way to find out, let your ears tell you.
There are lots of cords available out there, new & used at all price points. Take a walk on the wild side, buy one or two and test them out.
