power cable factory versus brand name gauges


Hi I have a few 12 gauge power cables from amplifiers that i have bought and sell. They all seem to be built the same, very thick and hard to twist or bend. All are built as 3 wires inside another insulation. I have cut open one of them, all the three wires are stranded and seem to be copper, at least the copper look very shiny instead of oxidized which is good.
I have finally started buying some brand name cables like Nordost Shiva and Vishnu. However they are all of smaller strand wires, namely, built as 16 gauge wires.
I guess I need a refresher course in electricity, why would these 16 gauges be better than the 12 gauges wires i presently have? Would the stranded 12 gauge present a lower resistance and capacitance? What is this argument that a wire has 90% transmitting at speed of light? I am a bit confused as people say they hear a difference but what would make the difference?

Accuphase explicitly notes in their manual to only use their stock cord. I’ve tried several upgraded cords and so far always preferred the stock. Stock cord is more transparent with a more open soundstage. Upgraded cords are darker with a more up front image, slightly more bass but a less transparent image.
