These are critical elements to obtaining world class performance in many systems. The impact of reducing chassis noise is a key element of the Harmonic Resolution Systems technical approach to high performance audio. The HRS Damping Plate/Nimbus System incorporates a highly effective design to eliminate component chassis noise revealing a new level of musical performance. They are precision manufactured from billet machined aircraft aluminium and proprietary HRS polymers. A very specific amount of mass, stiffness and damping from these products eliminates chassis resonance problems and transforms residual chassis energy to heat. This is a special system utilised by audiophiles and industry professionals as their reference chassis noise reduction system.
