The Alpha Quad Active is described as "Active Shielding". It uses a plug-in module whereby DC voltage bias is applied to the shielding (outside the signal path), effectively buffering out EMI and RF before they can enter the ground circuit. The result is a splashy, high energy cable that's fast and unreservedly dynamic and detailed. The Alpha consistently feels like driving the beat forward, as if it fed on the excitement and tempo.
