    I worry about those right angles that the electrons have to go around. They would have to slow down to make it safely. If they slow down too much, it may create a phasing problem.

    Every time you double the wire you go up 3 on the AWG gauge, so two strands of AWG 24 would be the equivalent of AWG 21. I'd rather just use 18g or 16g tinned bus wire. Which I keep on hand...

    I was wondering the same thing. They are essentially bleed resistors?

    Yeah, I love my massive tinned bus bar. FWIW Doug also sells 20ga bare tinned wire you can use for lacing if you prefer.

    But if I'm honest with myself, 21ga is more than adequate. I run 22ga from the filter caps to the power amp ground. Many people do. How does the ground current get on and off our preamp bus? Small, sometimes very small, component leads, maybe 22ga wire if we have it handy, and in my case, at least, a single 24ga wire to a ground lug (note isolated input jacks).

    It's actually the opposite. The popping comes when an uncharged cap is switched in. Once it's charged, it no longer pops, even without the resistor. The resistor is to allow the unswitched cap to charge up, so when it's switched in, it won't cause a pop.
