I'm not sure what you mean when you say, "what i'm not seeing is"
I do Not believe in all the cable lore BS myself. I personally run 10g KnuKoncepts speaker wire. It's not exotic nor expensive. It doesn't magically change my sound in any way shape or form. It's just well made, priced right and is easy to work with. It just performs as it should for the power being pushed through it.
What I do believe is, for the extra few pennies it cost's. I would go for 10g over 16g wire. It's about having the least resistance possible without going crazy. So if im wrong about using 10g wire, I guess everyone should start on Gene to, seeing that is what he also uses or used to anyway.
However, as i tried to make it clear ( which maybe i didn't). If some guy say's he swapped from 16g wire to 11g wire and he and his wife heard a difference, im not going to argue with him telling him it's just a placebo effect. Whether may be true or not. With all the factors coming into play ( amplifier, wire resistance, speaker impedance rise and fall), im just not willing to say it's impossible to notice a difference.
When it comes to audio, all the science and numbers can say one thing, but what we seem to hear doesn't always agree with the science. Sort of like some people think some old tube amp sounds better than an class A/B amp with stellar tested out specs to verify lower distortion. But the guy still thinks his tubes sound better. Same goes with different DAC's, some people actually prefer a DAC that actually measures out horribly.
When it comes to the audio game, there is no one set of standards that suit everybody. Since we all hear things a little differently, i just believe regardless of what the science say's. A person should go with what they find to be more pleasing to their ears. If that includes some placebo effect or not, it's not going to affect me one way or the other.
