Power cable education needed

I think I understand your point...I just can’t explain it. Let me try though, if you had a giant power cord, like half inch thick wires And a circuit blew inside the appliance it doesn’t matter how big the wire is before the fuse...It’s not like the large wire is holding a huge amount of electrical current as if it was water. The fuse was low and that would be the end of it. Am I close? Thanks for pointing that out

They don’t limit anything. They burn up, dutifully sacrificing themselves so your transistors don't.

Here's an easier way to explain it. 

The gauge/composition of the power cord stops mattering the moment the current hits the very tiny gauge wire on the other end of the power supply connector.

As long as the wire is heavy enough to handle the peak current draw of the amplifier without catching fire, it literally doesn't matter after that point. 

But, again, if you're enjoying your $800 power cable more than the stock cable that shipped with your amp, good for you.  Keep enjoying it. 

So then can you please explain to me what these giant power cords bring to the table? I purchased a couple and I couldn’t notice a difference. I’ve got good hearing and approximately 50 K in my system. I’m trying to figure out what a $10,000 Power cord brings to the equation. I’d love to have an explain to me. Thanks

It's hard for me to explain, too. But, let's say you're replacing a power supply for your laptop or something. You need one with exactly the same voltage, probably 19, but the amps doesn't need to be exact. When the laptop says the power supply is "19V, 5A max," it means 5 is the max amps the device will ever use. So a 19V, 10A supply won't hurt it. The only reason it would draw more power, measured in watts, which is volts x amps, is if there were a short inside the unit, or maybe you attached a 32V supply, or something. In that case, the fuse will burn, cutting all power. Putting a larger fuse in your amp won't supercharge it. It only puts the component in danger. It's like bungy jumping off a bridge and adding 30 feet to the cord so you'll have a longer ride.
