We review a lot of cables in Hi-Fi+. Most of them differ from one another by virtue of materials science, type and number of conductors, connectors, or the way those conductors interact and intersect with one another. However, Wire on Wire Experience880 is genuinely different. Wire on Wire’s unique take on audio cables is wrapped up in what it calls REDpurl™, or ‘Adaptive Asymmetric Geometry’. The materials involved are good – multi-stranded silver-plated copper conductors wrapped in blue or white PTFE dielectric with KLE copper Harmony connectors – but it’s the way they are used that makes Wire on Wire so special. The fully exposed geometry looks a little like someone was trying to build an interconnect cable while under the influence of some pretty strong LSD; the asymmetry of the braid looks almost chaotic at first glance, but shows a complex geometry that is designed to allow key parameters of cable design to be altered ‘on the fly’.
This adaptive geometry creates small but significant changes to the inductance (and thus the series capacitance) of the cable, and in an analogue environment where the cable is a major part of the interface between the output impedance of one product and the input impedance of another, those small but significant changes can dial in improvements to important parameters of the overall sonic performance. These inductance changes are created by adding small spacers in the larger gaps (‘tune loops’) in the braid of the cable itself. The provided booklet includes a small list (I’d call them ‘recipes’) of specific spacer placements to change the system’s presentation. These recipes are not meant as the only positions for spacers and experimentation is encouraged, although over-stretching the conductors (for example, by trying to shoe-horn spacers into the regular, tighter loops) is not recommended and not covered by warranty.
