Not to turn this thread into a cable debate, let me say it is not just the materials (e.g. silver, silver plate or copper) but the method of casting that makes a sonic difference. Ohno Continuous Casting produces internally the smoothest material which I think is key to the sonic improvement.
spook76, you are correct. There are plenty of other threads addressing the cable debate...it wasn't my intention to lead this thread down the wrong track...especially that one.
