I was using Nordost Vishnus in my mid level system. A clear improvement over stock. But they too were somewhat stiff. Replaced them with Morrow MAP3s which sound just as good as the Nordost and are quite flexible. If I get the upgrade itch I will climb the Morrow ladder before going back to stiff power cords.
Do good power cords have to be stiff?
As far as I am concerned, stiff power cables are a pain in the butt. Wonder if anyone has found a great power cable that is very flexible?
