Mike,
what happens when you coil an ac cord? does it create hum?

My point here is with regard to the power cord length, the power is always at the end of the wire regardless of it's length from the source, or am I missing something really basic?

It's a pretty reasonable question

A couple of things that get overlooked, or perhaps misunderstood in the differences between AC and DC electron flow behaviour, are:

• In the US, 30 times a second the component is at the start, not the end.
• In an AC circuit, everything is connected with everything else, and forms a complex network. The connection doesn't have to be the AC cord - any galvanic connection, such as IC cables, will influence the AC circuit.
• The AC circuit does not see any cable in the system/network as a piece of wire. It sees it as a component - with resistance, inductance and capacitance. So best to have each side of the stereo output identical.

Further, any filtering from AC cables or power conditioners is not just for noise coming in on the external AC line, or for RFI/EMF environmental noise - but at least as much for the noise generated by each piece of equipment back into the circuit. Some cables are better at this than others.

A coiled speaker wire makes a resistor and attenuates frequency, often used in speakers as part of the crossover.

I may have spoke out of turn as I am not sure if the same applies to AC power cords.

I do know that a coiled power cable does make for lightening protection. If a large power surge such as a lightening strike passes down a coiled PC the cable will burn the distal cable and protect the equipment at the end of the cord.

Mike, what is the distal cable you refer to?

Sorry, too much medical lingo.
The proximal end would be the front end of the PC hitch plugs into the wall.
The distal end would be the back end which plugs into the equipment.

If lightening were to strike your house and you would be so unfortunate as to have it find its way to your power outlet connected to your stereo the intense heat generated would cause the PC to burn through the insulation of the PC as it enters the coil and the insulation of the coiled PC disrupting the circuit before the intense electrical pulse could reach your equipment.

I hope that makes sense.
