Do good power cords have to be stiff?

I see LOTS of power cables speced at 14 Ga.

i agree

zu’s are very nice cords and very flexible

i’m not crazy about sean casey’s speakers, but his cables are excellent, i have a lot of them, great value and performance

I use 6N PC4030 Acrolink power cord on my Esoteric UX-3.

     It’s amazing to me: they were able to configure two 9 AWG conductors, plus an 8 AWG ground, in a 3/8" diameter PC, that’s even more flexible than the typical, stock IEC cord.
