The Au24 line of speaker cables take a different tack from many other cables in the same price range. Their construction is intentionally low mass -- connectors, insulation materials, and conductors. The conductors are so-called "single-crystal copper" with polypropylene insulation and a cross-linked polyethylene jacket. Audience says the geometry of the conductors lowers eddy-current resistance compared to other designs. Eddy current is produced in conductors when the electrical field around a wire collapses. This happens constantly with audio cables as the signal varies continuously between negative and positive. Each time the signal heads towards and reaches zero volts, the field collapses around the wire. This collapse induces a current in the wire. Audience believes the reduction or elimination of this induced current is one of the keys to making a good-sounding audio cable with excellent performance in the time domain.
The Au24 listening experience is less "audiophile" and more "music lover."
