"It’s hard to assess the often outlandish claims for high-end speaker cables
; it can seem a fairy-tale land where sales patter and snake oil combine to lubricate pricing until it climbs to seemingly outrageous levels for cables that may appear, at least externally, like any number of other cables.
On the other hand you have cable companies that have designs which are entirely unlike any other cables and are clearly highly engineered for their purpose. One such is Inakustik, a German company which has been making cables since 1977, and whose use of ‘air technology’ insulation in its cables delivers a unique take on cable dielectrics.
The approach – and the resulting cable performance – has convinced Tim Wallis of Inakustik’s Australian distributor Audio Marketing."

As I keep saying though it would be interesting to compare these agains my less than £2 a meter over 500 strands speaker cable (for me with a 30 foot length though the price differential is somewhat greater)
