My first impulse was to dismiss the Palladium interconnect as garbage (albeit expensive garbage) - but as I have been thinking about it a little more, it might make some sense.
Electrical resistance is not the limiting factor in interconnect performance, as it is in speaker cable performance. The goal of the interconnect is preservation of a small signal from effects such as inductance, capacitance and other perturbations that may be caused by things such as grain boundaries, surface defects or impurities in the wire.
Although I doubt that Palladium (expensive, stiff wire) is a very practical solution
, it may offer some advantages over silver or copper with regard to the latter parameters. It is, for example, more stable against oxidation.
