In the beginning there was zip-cord Then there was heavy zip-cord, followed
by designs weaving cable for low inductance or spacing it for low capacitance.
Eventually, cable was fabricated with fat wire for the bass, medium wire for
the midrange, and tiny wire for the hi I: frequencies. Exotic materials, such as
oxygen-free copper, pure silver, and 7§flom were variously employed.

Now there is WeberWirr, anti-resonant, distributed-
impedance audio cable for amplifier to loudspeaker signal
transfer WeberWire was created by Jeff Weber, Gramm
winning record producer, as a completely neutral tran er
path between amplifier and loudspeaker to facilitate evalua-
tion of original master tapes. Scientifically constructed of
the highest uality metals and organics,WeberWire requires
no external ampers or phase correcting" networks to func-
tion as the most advanced audio power signal transfer path.
