Bright Star's Isonods are for customers with two types of pursuits. Type 1: your turntable is skipping when you walk by and you need to take further measures of isolation. Type 2: you want to tweak your system if every way possible in order to get the highest level of performance from it. Isonods not only prevent vibration-related skipping, but they also will also yield more quiet backgrounds and heightened clarity. Their effect is most profound on turntables, but they're also effective for CD players, amps and speakers.
