It appears that you’re interested in Kimber Kable. I can’t speak to all of their products, but it appears that their primary design revolves about a litz braid. I do not have any personal experience with Kimber Kable, but assume them to be a quality product; however, before I purchased cables from Kimber Kable I would take a hard look at Iconoclast by Belden. The engineer in me really connects with the Design and Technical Papers that are available to explain the "why" for the Iconoclast cable designs. I also appreciate that the designer, Galen Gareis, acknowledges that he can hear differences in things that he cannot design for. In comparison to Kimber Kable, the Iconoclast speaker cables also use a braided design, but are taken a step further by flattening the braid out. Their return policy appears to be very generous so if I had the funds to support it, I would give them a try.
Generation 2 speaker cables and the 4x4 Generation 2 XLR interconnects are pretty cool designs/concepts.
