I bought these new in 2010. When I upgraded last year to Wilson WP7s, I came across Wilson's recommendation against using "braided litz type loudspeaker cables". I loved the level of detail that these cables produced in my previous WP 3/2s.
"Kimber 12TC consists of 24 individual TC conductors (12 white, 12 clear) in a larger format braid. Kimber's patented Varistrand technology incorporates specifically selected strand gauges within one conductor made from hyper-pure copper with first-quality surface finishes. The aggregate wire size is equivalent to two #8 AWG conductors. Complementing the advanced metallurgy is 12TC's custom Teflon dielectric."
