Serious Question About Silver vs Copper Conductivity for Power


Yes, I realize that this topic is going to bring out the sharks, but if I get at least one serious response, it will all be worth it.

I understand that silver conducts 7% faster than copper.  I also understand that using a dielectric insulation like Teflon is best at keeping the wire from overheating, stopping signals entering and stopping signals from leaving the conductor. I understand that a certain amount of math is involved in selected gauge of wire depending largely on how much power the component is going to take, and how much the amperage is (20 or 15).

My question is regarding certain features applied to either silver or copper conductors that may or may not have an advantage over one or the other.

I have the Kimber Kable P14 Palladian.  This uses 14awg copper conductors insulated in Teflon.  Then it adds a massive filter that attempts to mitigate the standing wave ratio to as close to 1:1 as possible. I had Kimber’s Ascent power cable prior.  It’s identical to the Palladian, except the filter. I have heard the difference between using those two cables.  Apparently, mitigating the standing wave ratio lowers the noise floor significantly. However, any filter that chokes the signal and will slow the electrical current.

As I understand it, the amplifier works by opening the rectifier to allow the capacitors to fill with energy that the system will draw from.  Being able to keep the rectifier open and fill the capacitors as fast as possible, reducing lag time, has the effect of creating more realistic and detailed sound.

With that said, changing to a power cable that uses pure silver insulated in Teflon, will ensure that power is delivered potentially faster.  Although, the silver power cable will NOT have a filter.  Therefore the standing wave ratio will not be mitigated and the electrical signal will not be choked either.

So, would the amplifier benefit from faster electrical current or slower, but cleaner electric current?  Since this signal isn’t directly applied to sound, the concepts of “colder” or “warmer” sound should not apply.

Can someone help me out without poking fun at the question?  Additionally, I am not interested in having a cable-theory debate.  If you don’t believe cables make any difference, I will not debate or have discourse on that topic.

The power cord does not have any effect on the filter capacitor charging time. The filter cap discharges when the rectifier output falls to zero and charges when the voltage from the rectifier exceeds the voltage on the capacitor. The charge time depends only on the power supply load resistance multiplied by the capacitance (RC time constant). For a cap to charge faster, the capacitance must be larger, and a larger capacitance results in a higher current draw. This higher current is sourced from the transformer secondary, which must have a high enough VA rating to meet the speaker load demand.

As long as the voltage from the wall receptacle isn't reduced, the amplifier will preform to spec. A larger gage  power cord will lessen any voltage drop more so than if it's copper or silver. You will need a power cord length of a 1,000 feet to see only a 1-ohm difference in resistance from copper to silver.

I'm not going to dive into whether one sounds better than the other, but from a physics point of view a six foot silver or copper pc the same gage has no electrical differences at 120 volts at 60 hz.
