Gold Connectors make some more noise, the reason they use the TiO2 gold plating is because of corrosion. But then i sugguest you just solder them, thats even better then gold.
Mjah i don't really believe in those golden ears, mostely they just hear different 'subtle' changes but in reality it is just nonlineair distortion because of amplifier limitations.
Those people must have just terrible nightmares when they go visit a recording studio and see that the audio already has been trhough miles of cheap audio cables and not plated connectors etc etc.
Yet i have to admit that sometimes the volume remastering could be done better.
