Interesting thread.
From personal experience though, not sure I’d agree with heavier gauge speaker cable always being better?
I’ve used all shapes n sizes of speaker cable in my kit over the years, some thick as yer wrist down to DNM at a single solid core strand, and can’t say I’ve ever found a link between cable thickness and sound?
Best sounding speaker cable setup I’ve heard in my system looks like shoelaces, and isn’t even terminated.
Not exactly thick cable is it?
My speakers are Triwirable (3 sets of binding posts) and run a single length of cable through all terminals.
Compared to shotgunning 2 and 3 lengths of cable, and various speaker jumper options bridging terminals, turns out simplest sounds best.
The cable is tin plated, so no concern of oxidation using bare wire.
The Duelund DCA16GA cable I’m using now ousted a £1K speaker cable and sounds good enough that don’t even think about speaker cable nowadays.
Just mentioning is as an alternative maybe not considered if your interested in DIY speaker cable.
