I can't tell which way @seeteeyou is leaning towards w.r.t. my question . But what you're quite right that components the way are relevant to ensure no bottle necks. Which is why I'm generally not so keen on expensive cables that are terminated with gold plated plugs.
The purpose of gold-plated plugs aren't meant to improve sound quality, although some may argue that point. Any cable maker or plug manufacturer worth their salt are doing so for the simple reason of degradation prevention (erosion, tarnishing, etc.). As for the wire composition, that is what we fanatics like to debate, but yes you are correct gold is scientifically not as conductive, which may explain why it has sound characteristics of its own.
