The most important thing to remember is the is an appropriate cable gauge size for power. silver is far more efficient than copper by its self. some electrical standards for regular copper stranded 10 amps at 120 volts is or 1200 watts or typical 18 guage wire load max; 15 amps at 120 volts is 1800 watts or a 14 guage wire load; 12 guage is 20 amp or 2400 watts or 10 guage is 30 amp or 3600 watts. Essentially 10 guage wire could drive a 3600 watt speaker before needing to ever worry about over load. bigger is not always better. why well some basic math the square root of watts multiplied by the square roots of ohms tells you the accurate average sustained volts any amplifier outputs to speakers. so for example 200 watts at 8 ohms 40 average volts to your speakers, 200 watt 6 ohm about 35 volt, 200 at 4 is 28 not quite 29 volts. voltage rate and current amplifier rates can very based on max volume peaking volts but not standard volume operations. another tip of ohms law and psychics more volts equals lower current, more current is lower volts. keep in mind amplifier damping factors are diminished by having over sized cables or conduits, and your signal and detail especially at lower volumes will be lost or absorbed by a huge cable, especially if one is just running 100, 200, 3 or maybe even 400 watts per channel. Silver is twice as efficient as coppers conductivity very important, less is more so with the Baldur speaker cables being 12, 26 guage conductors each leg or lead, is 16 guage of silver. 24 conductors total per cable. 16 guage silver is at least 2000 watts potential of speaker driving before worry, remember 14 guage copper is only 1800 watts. you also impair perspective proper timbre of the sound harboring more bass or low frequency via too large of cables. I use Nordost speaker cables for this reason, no exception. This is why audioquest and some other cable maker have to put those battery warmer packs on their huge cables because the massive inductance and resistance and capacitance.
