No one actually knows how to lculate what speaker cable they need

It would be interesting if the first 3 AudioGon members are still using the DIY cables. Please chime in. The latter 3 are not AG members.

I swapped mine out for solid silver cables. Partly to tidy up on the cables in what is a fairly tight space.

Wow! 4 gauge solid silver. That must have set you back a bunch.

Not quite. I didn't stick to the rules about gauge for these.
And I was on 0 gauge before. :)

I ended up not playing... I wanted to though as I was curious but as the thread went on I lost interest. Interesting thread and been fun to read but I agree with most and question the OP for being so secretive on his formula. Instead of blowing the money on the battery cable I bought a couple power receptacles and am very happy with that purchase.
