Golden-eared metalurgists - does gold poison solder joints?

Posted by Francois G on December 21, 2009 at 09:01:28:
In his Aikido instructions John Broskie says that "even a few molecules of gold will poison a solder joint". Gold plating on some resistors (Riken for example) and other parts for audio purposes is supposed to be bad for a good-sounding joint.

Has anyone experimented with the sound effects of gold plated parts in solder joints? What have you observe?

Given the fact that Mundorf sells expensive and apparently successful gold alloyed wire could gold be that bad in a solder joint?

Thanks,
Francois
