Best Solder??

If a proper mechanical connection is made, does the solder really make that much of a difference?

I don't think solder has a "sound",but hey, what do I know.

Tpreaves: dont feel bad, I'm still trying to figure out why it's not spelled sodder.

Rja,
I would be careful with some of the "audiophile" solders. Some have pretty corrosive flux in them. IF you dont clean it all off, will eventually attack the joint.

In one of our audio club meetings, we had one demo where we tried different solders. They do make a very big difference, bigger than I would have thought. The other thing is you need to have a good mechanical connection over time.

we ended up picking Kester 63/37 with a 285 flux as the preferred choice. 63/37 is also eutectic, which most others are not.

Mundorf supreme 9.5%silver 4% Cu, and 0,1% gold- its melts very good with stock soldering iron, with soldering station 460'C even more. it "sounds" smooth comparing comapring with WBT for example. its good or bad depends on system.
