Cable Reviews

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.

When no one's watching, it's easy to express your opinion. When tens of thousands of people are reading over your shoulder, it becomes more difficult. In fact, it can be downright creepy—especially when what you're thinking sounds like one of those grand, all-encompassing (over)statements you yourself tend to distrust. You don't want to be wrong; on the other hand, if you're too much of a wuss to express what you reallythink just because someone might take it as grandiose, then it's time to give up.

The possible approaches to any technical problem range from trial and error to first-principles physics. Then there's the "purist" approach—the simplest, most direct way to meet the challenge. Often, the purist approach doesn't pan out because of such phrases as "we need 60 tons of molten gold" or "can we cool the entire building to absolute zero?" But in the world of high-end cables, the purist approach is viable, and is exactly where you find Jeffrey Smith.

Introduced in 2003, Siltech's G5 Classic series of cables evolved from their highly regarded Generation 3. The G3 series introduced a new metallurgy in which small amounts of gold were incorporated into the silver used as conductors. The G5 Classics use a proprietary geometry called X-balanced Micro Technology, which, according to Siltech, makes the G5s the quietest cables, with the lowest distortion, to be found. Kapton, Peek, and Teflon insulation is used, and the cables are designed to minimize the pickup of RF and EM interference, with low inductance, low capacitance, and low resistance as design goals.

A man dies and goes to hell, and Satan meets him at the gate: "Just this once, I'm going to let a newcomer choose his own torment," he says as he leads the deceased from room to room, opening doors on all manner of abuse—burning, flaying, Lou Reed's The Raven, you name it.

Being a metallurgical engineer, I've always been intrigued by audio cables—their construction, the materials they're made of, how they're produced, and, of course, how all of that relates to their sound. Over the years, I've auditioned a wide range of cables, from Nordost's round conductors in a flat cable, to Alpha-Core's flat cables in a round conductor, to MIT's complex termination systems. I've even got a closet full of cables—some quite good—from companies that no longer exist.

The dCS Verdi/Purcell/Elgar system's ultra-high resolution and superb focus, and its ability to drive an amplifier directly, provided a good opportunity to compare my current reference cables, Harmonic Technology's Magic Woofer ($2000/8' set) and Pro-Silway II interconnects ($399/m pair, $240/add'l. meter) with Analysis Plus's far less expensive Solo Crystal Oval 8 speaker cable ($969/8' set) and Solo Crystal Oval 8 interconnect ($399/m, longer lengths available).
