re showers: Providing a cable is up to spec, you can't improve it. you cant then make the shower more...showery...by changing a cable. If the cable is thick enough then there will be next to no voltage drop and that's the end game. That's it. slightly underspec the cable and the voltage will drop, the shower will still work but not at 100% performance. Go wildly underspec and the shower will still likely run, only now you risk setting fire to the cable and burning the house down. That's assuming the shower unit doesn't shut itself down before that happens of course.
If that's exactly the same as a power cord for an amplifier, as you claim, then I think you've just answer the question. Only not in the way you intended...
