Yes, the SR is much different, according to their website they do this:
Conditioned with a proprietary treatment that alters the conductor at the crystal structure and then treated with 2,000,000 volts of electricity which alters the conductor at the molecular level, the Synergistic Research Black Duplex is truly state-of-the-art. Materials include UEF Coatings and Graphene with 8-million times the conductive density of copper. Synergistic Research’s new UEF Black Quantum Duplex will revolutionize the way you plug in and tune out!
