DIY Jumper Suggestions

To clarify, I use silver foil for long speaker cables, but 8awg silver round wire for jumpers.  It's difficult to use bare, unterminated foil as jumpers.  And for jumpers, why would one want to resort to spade terminations with degrading solder and metal-on-metal junctions? 

Agreed! Thanks so much!

Any reason you stacked them vs parallel (side by side) with a slight say 4-5 mm gap between the two or three runs. 

I’m unsure which approach offers the least capacitance. I stacked them partly for aesthetics, but mostly so that the compact stack, bound together with one final jacket of teflon tape, can be drawn easily through a silk jacket for damping. For shielding, the silk jacketed bundle is then pulled through a tinned copper braid tube and finished with tekflex. Both ends of the copper braid shield are soldered to external ground wires. The ground wire at the amp end connects to earth ground. The ground wire at the speaker end connects to the metal driver baskets.

Ok.  I would think stacked is much higher capacitance.   Curious why you felt the need to shield these speaker cables? Sorry for all the questions, but your build sounds most interesting to me.
