Will increasing speaker cable AWG make a difference in sound quality?

As a long time user of (small gauge) Audience speaker cables, I am skeptical. I have tried highly regarded, larger gauge cables (e.g. PAD, Inakustik, etc.), and have always returned to Audience.

I am not arguing that thinner gauge is better, but doubt that there would be any meaningful differences.

When you go up the AQ (and some other manufacturers) cable line you don’t only get bigger gauge wire. You get better quality materials and better connectors. You have to figure all this into equation. And connectors do make a difference.
All being equal, will you hear the difference between the same quality cable of 12 and 10 awg terminated with the same connectors? I guess it’s possible but depends on a lot of other factors.

I learned something about cable here, always been wondering why cables sound different from each other when they should not have, especially for the better-constructed ones.  

Snake oil at its best!!!!

Maybe the only way to know is try it.
