Tech journalist Lee Hutchinson approached the JREF after writing an article for "Ars Technica" about directional Ethernet cables that claim to "keep your audio signal completely free of electromagnetic interference". The MDC set up a controlled double-blind demonstration with volunteers listening to two identical recordings with a randomly selected Ethernet cable, a normal one or the cable claiming to improve the listening experience. After six volunteers, the demonstration was called off, as they were unable to select the "enhanced" cable over the common cable.
