Black Sand Power Cables are very flexible and a good value. Currently using Audioquest Hurricane's in my system. Their Litz geometry makes them somewhat flexible. The Audioquest Storm series is the only cable I have used that made a immediate and dramatic improvement in sound. I was not a power cord believer until I tried the Audioquest cables. I have done enough A/B now to know it wasn't that glass or Cabernet.
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?
