Outwardly, there's not a huge amount of difference between many of Kimber's speaker cables. They tend to use multiple, individually insulated conductors twisted together in a special weave, with low-loss insulation.

In the case of the 4PR reviewed here, there are four conductors per side and insulation is simply polythene – a recipe apparently unchanged since the earliest days of Hi-Fi Choice back in the 1970s!
