I've done a lot of listening with different types of metal connections. I think there is a challenge with mating connections based on surface contact only. Examples of this are power plugs and interconnect plugs (RCA/XLR). If you are not using a soldered connection, then the surface material of the mating metals has a huge contribution to the sound. In my experience, copper on copper or unplated-copper is not a good idea and creates a "ringing" distortion in the midrange. This is where different plating really helps (such as gold or rhodium -- or even silver-plating if you like that sonic signature).
Where is the optimal place to have an interface between two different metals?
hey-o!
it is pretty well established scientifically as well as anecdotally that at an interface of two different conductors composed of two different metals, distortion of a signal occurs. this leads many to choose receptacles and power plugs (as well as IEC inlets and connectors) made from the same metal.
my question is this: where is the best place to have the interface between different metals in order to reduce distortion? there obviously needs to be some type of interface since in-wall wiring is copper and internal component wiring is often copper as well. so where does it make the most difference? is it in the receptacle/plug interface where everyone who cares about this focuses their attention? or do they focus their attention here because any of the other interfaces are too much of a pain in the ass to change? what about the power cable itself? i see lots of people who like rhodium plated recept/plug combos, but i've never seen any mention of rhodium plated cable.. so there's an interface between two different metals where the connectors join to the cables...
i truly am curious and would love your thoughts and discoveries on the matter.
