And the cable......?
REDGUM 'Expressive line' - High Damping-Factor Loudspeaker Cable - better than
1.9 milliohm/meter - Manufactured in Australia.
This 10mm copper speaker cable has been specifically chosen to match the high
damping-factor found in all REDGUM amplifiers.
Let's rethink whether copper cable should be stepped over in favour of silver.
Consider the Resistance of 10mm cable at room temperature:
| Element | Electrical resistance (ohm/meter) | % change |
| Silver | 0.001586 | |
| Copper | 0.001678 | 5.5% higher resistance |
| Gold | 0.00224 | 30% higher resistance |
| Aluminium | 0.002655 | 40% higher resistance |
| Platinum | 0.0105 | 85% higher resistance |
So, a copper wire 5.8% thicker than a silver one will have EXACTLY the same resistance.... hmmmmm.....
International price on silver is around $US4.50/oz = $US 72.00/lb
International price on Copper is around $US 0.76/lb
In sum, silver is only a better conductor by 6%, but with a 9500% higher price... hmmmmm.....
OR...
For the same $$$ you can have a 10mm copper cable or only a 0.1mm silver one!!!!
Interesting choices, hmmm?!
