Audio connoisseurs know that all links in the signal path are as important as the next. Furutech engineers solutions that optimize every pathway and junction; any unaccounted for characteristic weakness (i.e., contact resistance, EMI-radiating junctions, RFI) diminishes performance as noise and distortion builds. Using the best materials and processes available along with meticulous attention to build quality is a large part of the Pure Transmission engineering equation: The fuse is equipped with rhodium-plated OFC copper caps and a special low-inductance copper alloy conductor, ceramic body with special damping filler. All metal parts treated with Furutech?s patented Alpha Super Cryogenic and Demagnetizing process. These beautifully made audiophile fuses are engineered to withstand 1 nanosecond at a full 1500 watts, and rated at 125mA/6.3A.
