> Gold containing solder, on the other hand, is nonsense.
Well, actually™, it turns out gold-tin alloys (which is what this probably is) get used a lot for solder, particularly in optoelectronic and microelectronic device packaging. You may already know this, but I didn't until tonight, when I thought, "Hey, is this really a thing?" and looked it up. :)
(I can't see anything that suggests it helps with "clearer sound," of course. I also searched for "audio-grade solder" out of curiosity and it seems there are some companies that market solder that way, but they seem to generally be (a) silver alloy, not gold, and (b) regarded rather skeptically.)
I actually didn't know about that one. Sounds like it's mostly for specialty applications though (e.g. ceramic packages). Looks like it's something like 80% gold, so that would get expensive really fast if you attempted to use it like regular solder :)
