Mike;
Those must be the mid priced speaker cables, everyone knows that the best ones are made from copper, and nickel extracted from meteorites, and plated with Welsh gold, otherwise they have to use an alloy of cesium and Dalekanium, with a touch of strontium 90, but those are harder to find, as well as needing to be shielded in lead. It's like the phonograph stylus can only be made from Sapphire mined by spider monkeys in Eastern Borneo, otherwise they need to use blood diamonds from Northern Antarctica, mined by Orion slave girls, but only virgin ones, (the diamonds not the girls) on Captain Picard's birthday, and those are much too expensive.

Arran
