NBS has several basic designs with distinctively different sounds. The King Serpent group tends to be warmer, a bit relaxed and not as analytical as the other group. I like these speaker cables a lot.
NBS cables are extremely stiff. With the King Serpent, the part that connects to the amp and the speaker (the leads near the spade lugs) are stiff and brittle and should not be bent sharply. The cable should also not be bent repeatedly for the same reason (the conductor inside will break). This happens quite a bit with dealer demo models from constant removal and reinstallation. You should make any necessary inquiry about the condition of these parts of the cable.
