Nirvana Audio's cables have long been fixtures in my audio system: first the SL interconnects and speaker cables, and, after their debut in 1998, the S-X Ltd. interconnect. In 2002, after a long development process, designer Stephen Creamer introduced the companion S-X Ltd. speaker cable ($2780/2.5m pair, add $50/pair for biwire configuration). He explored a wide range of options, including dramatically different structures and materials, but always returned to the elements he'd used before—and ended up with a design that combined elements of his two existing speaker cables, the SL and the entry-level Royale. At its core, the S-X Ltd. has the Royale's two conductors, each a symmetrical Litz element consisting of 285 isolated strands of high-purity copper of several different gauges. In the S-X Ltd., the conductors are spaced slightly apart to minimize capacitance, wound into a twisted pair, and wrapped in FEP insulation.
