Heavier guage cable does not cost more to make. Since copper and silver are not really expensive materials.
IMHO, tiny guage cables tend to preserve the music signal better than larger guage cables. I use Audio Note Silver Speaker cables and they are about 16 ga or thinner. I was sceptical at first about the bass but guess what???? Bass was the deepest, quick, without BOOM and clarity without harsh and shrill. Beats cables 10 times the thickness.
One other thing about thinner cables....there is more finesse in the music too compared to the thicker cables.
