They are constructed with 100% Noise free, Spiral Shield, SabreCable wire. As with all SabreCable products, they are fabricated under the tightest of quality control measures. Soldered connections are facilitated at the highest possible temperatures. 90S instrument cables are thoroughly tested and are also covered under a lifetime warranty against defects in material or workmanship.
