Best DIY power cable. Why not make?

No, you're not. You are not a "gullible" one, remember? Although they might sound good in your fantasy system.

I’ve been making my own power cables for years using long crystal oxygen free aluminum shielded unobtainium with Ophidia oil tm.   The cost is astronomical however it sounds just as good as three pieces of electric taped coat hanger bare ended into the wall socket.  Sorry guys I don’t believe in power cord magic. I can hear a difference in bi-wiring and in using a power conditioner and things people think I’m crazy for doing, but not in what you plug your appliance in with. If I’m wrong educate me. I am educable.

Have you tried using any aftermarket cord?

 Would be the benefits? My amp is already dead quiet.

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. 

All the best,
