Vibration isolation for all Bassocontinuo designs and builds all of their fine audio furniture in Italy. The Proton is part of the company's Genesis Line, the most affordable series in their lineup. This rack offers exceptional performance and a clean, understated look. As Bassocontinuo says, these racks are for real listeners, not big spenders. The Proton is full of science-backed vibration isolation tech and helps improve the sound of your system. Each of the three shelves can support up to 88 pounds - perfect for amplifiers, receivers, CD players, and more. Each shelf is isolated from the pillars by rubber washers. These prevent sound-muddying vibrations from transferring from the pillars to the shelf. The steel spike feet work well on carpet, and protective discs are included for hard floors.
