I love my Anti Cables flex, they sound amazing, won't totally bankrupt you, and they can easily go under a rug. They are stiff, but once you bend them into place they won't move. I was able to get them to go through my speaker stands which you will never do with more big thick cables.
They have amazing bass, totally liquid smooth mids, highly recommend their speaker cables, but the rest of cables are Acoustic Zen and Acoustic Revive.
