Building Speaker Cables

Seems that you are not really building cables, just looking to terminate them!  I think I have the same sort of semantic issue with silver soldering which can mean many things.

I have built all my interconnects and speaker cables. I use Bluejeans cable and furutech connectors. Great results. The sound just as good as some high $$$ cables that I had. And yes I sold the high $$$ cables. 

I built all of my power cables with Furutech components. It was a great project and the results were great. I have no idea if it made a difference in sound but I had a great time. I was able to make custom lengths as needed.

No matter what, that "marine grade" shrink tube is the key. You definitely want your wiring to survive a flood.

Connector metal to wire metal in a tight crimp or screw down is all you ever need. Adding solder may affect the electromagnetic properties at the connection points and degrade the sonic quality. If you are worried about oxidation, you can cut off the ends of the wire by half an inch and reterminate them after a few years. It typically takes that long to build up oxidation if they are sealed well.
