To use an analogy, if you have a water pipe that is fat at one end and thin at the other, and there is a lot of pressure at the fat end, the flow at the thin end will be lower than it would be if it were fat through its whole length. This is analagous to current (reisistance or impedance is analagous to pipe thickness, which regulates current/flow). But the water pressure will be the same at both ends. This is analagous to voltage. If you want to reduce voltage, you need to short the circuit somehow. In the analogy above, this would be like adding a joint to the pipe where you are diverting some of the water elsewhere.
I will be fascinated to hear how the voltage at the end of a Zu cable is different than the voltage at the end of a Senn cable.
Empirical measurements, or theoretical explanation backed by equations and a demonstrated understanding of terms, math, and physics, please.

I didn't say that anywhere. I only stated that cables differ in sound. And at the end, you use a plug, some plugs have more resistance then others, if you take these into the equation, yes some will have slightly higher voltage then others at the end of the line. Simple as that. You don't nead rocket science for that. Also, some cables have better frequncy responce, at the end, more frequencies come trough unharmed. This is partly due to the core used. I allready posted in several threads about the ultra high pure copper and silver cores. Expensive to make, but better in sound. they use a special crystal structure, wich is much more pure.
Why don't you explain it to me with Empirical measurements, or theoretical explanation backed by equations and a demonstrated understanding of terms, math, and physics nothing is happening in a cable.
"Voltage is a property of an electric field, not individual electrons. An electron moving across a voltage difference experiences a net change in energy, often measured in electron-volts. This effect is analogous to a mass falling through a given height difference in a gravitational field.
When using the term 'potential difference' or voltage, one must be clear about the two points between which the voltage is specified or measured. There are two ways in which the term is used. This can lead to some confusion."

"Voltage with respect to a common point"
One way in which the term voltage is used is when specifying the voltage of a point in a circuit. When this is done, it is understood that the voltage is usually being specified or measured with respect to a stable and unchanging point in the circuit that is known as ground or common. This voltage is really a voltage difference, one of the two points being the reference point, which is ground. A voltage can be positive or negative. "High" or "low" voltage may refer to the magnitude (the absolute value relative to the reference point). Thus, a large negative voltage may be referred to as a high voltage. Other authors may refer to a voltage that is more negative as being "lower."
I just measured two of the same outlets: one was 227,3 and the other was 228 volts. It should be 230 volts, so somewhere i lost a few volts on the way to me and they are certainly not exactly the same, as you stated!
So, apperently theory is not the same as practise.
