ABOUT US

David Salz, co-founder of WireWorld, became fascinated by the concept of special audio cables the moment he first heard about them. The year was 1978, and the first high-end cables had only been on the market for a short time. He eagerly tried every upgrade cable he could get his hands on. Next, he began building experimental cables by hand and comparing them to the production cables. The results of his initial experiments were inconclusive. All of the cables sounded different, yet none of them sounded consistently better than the others.
 
David realized that the most important lesson he had learned from these comparisons was that changing cables did not tell him what they were doing to the sound. This realization led him to an important discovery. In 1980 David began making his first comparisons of one meter interconnects to a two-inch pair. The sound of this “cable bypass” was a revelation. Suddenly he could hear how much music was being lost in the cables. Everything sounded much cleaner and more dynamic through the two-inch cable than through any of the standard length cables he had heard. Excited by his discovery, David quickly built several pairs of two inch long cables with the various wires and plugs that he had on hand. They all sounded nearly identical! In his words, “I was amazed with these results because I knew that I had discovered the key to solving the problem of audio cable distortion.”
 
David immediately began a detailed investigation into the audible effects of cables. The bypass tests that he used to sort out these effects were somewhat awkward and difficult to produce, but their effectiveness was clearly superior to any other development technique. From these tests, he learned that there was a clear scientific explanation for the sound effects of cables, which actually followed electrical filter theory. In 1981, David formulated a solution to the problem of audio cable distortion, his original Symmetrical Coaxial cable design. He also founded his first cable company, Straightwire, Inc., that same year. David has written about this next period in his audio cable odyssey…
 
“The next step in my research involved a study of cable production technology. I began by finding the products most closely related to my designs. It turned out that an existing wire technology known as Litzendraht, used for high frequency coils, was similar to my proposed design. I located an old Litz wire factory in Connecticut that was scheduled for closing. I arranged to visit the plant with the intention of purchasing machines to produce my cables. Not only did I purchase a group of machines, I was instructed on their use by a plant engineer with decades of experience in producing complex litz wire constructions. This training proved to be extremely useful in the years that followed.”
 
“As company President and sole designer of the Straightwire cable line, I began producing cables in 1983. By 1985, my designs were widely regarded as the most neutral audio cables available.”
 
After producing four generations of critically acclaimed cables, David sold his interest in Straightwire at the end of 1991. In January of 1992 he and his wife Lori formed WireWorld. After a few months of intensive research, including detailed bypass testing, they developed several innovations that produced great improvements over his earlier work. These innovations included Grain Optimized copper and solid silver conductors, proprietary connectors, as well as the patented optimization of his cable design concept, now called SymmetricoaxTM  (U.S. patent 5,298,682). The first WireWorld cables were an instant success, earning WireWorld the reputation as a leader in the high-end audio cable industry. Further research yielded a major breakthrough in late 1994. What began as a practical suggestion to save time and energy, developed into an important tool.
 
The WireWorld Interconnect Comparator provided the first scientific proof of the audibility and value of high-end audio cables. It received the Innovations ’96 award from the Consumer Electronics Association and numerous rave reviews and enthusiastic endorsements from respected audio critics around the world. The original Interconnect Comparator is operated manually, and is limited to comparing a single pair of cables to a bypass or one pair of cables to another. In 1998, WireWorld introduced the next generation of this concept, The Cable Comparator System, which allows three-way comparisons of both, interconnects and speaker cables from the listening chair.
 
The latest phase in the evolution of the Cable Comparator technology is the Cable Comparator Disc. This groundbreaking CD provides objective comparisons of the WireWorld Series 5 cables and the leading competitor’s cables to a direct connection, the only true reference standard for cable performance.
