The AudioQuest NRG-Z2 EU is a figure-of-8 that uses several principles found in the more expensive Storm series cables but at a reduced cost. NRGY-Z2 EU uses Perfect-Surface Copper+ conductors (PSC+) in a 7-strand Semi-Solid Concentric arrangement in which the strands never change position within the bundle. This technique significantly reduces strand-interaction distortion. The higher purity and fewer grains within PSC+ further reduce distortion.
All drawn metal has a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise drains away from where it will cause distortion. The AudioQuest NRG-Z2 EU has a Silver-Plated shield drain that efficiently removes RF noise from the line and neutral shields via the wall plug’s “ground” pin – which is why even the 2-Pole “2” models have an unexpected ground pin
