The most complete sound I have found has been silver plated copper (interconnect and speaker cable) and this has been also confirmed with several philes- friends in their systems. Many variables though can affect the sound however. Design/configuration, size/awg, termination quality, and termination choice....can't evaluate a silver copper wire if you are using gold spades...gold uses a substrate of nickel to aid adhesion and bonding. Resonance, capacitance, inductance, resistance are factors independent of material selection. Without an understanding of those properties,it is difficult to know if you are only hearing your material. PT
