    I know why its a good idea to twist pairs of wire carrying a dc signal.

    But ive seen top-end speaker(ac signal) cable pairs twisted, why?

    I dont believe its a good idea to twist 50Hz mains L, N together?

    Twisting a pair will make it less susceptible to outside noise.

    It will also improve attenuation characteristics at higher frequencies, but I don't think this would apply to audio frequency.

    Remember that much of what is sold in high-end audio is snake-oil.

    Twisting a 50hz pair should have negligable effect.

    I read a test comparing zip cord and monster cable and the zip cord did the same or even better at certain frequencies. :)
