“Do not underestimate the power of our Nimbus and Damping Plate products to significantly improve your system performance. They 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.”

Michael Latvis, Chief Engineer
Harmonic Resolution Systems Inc.
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 aluminum 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 utilized by audiophiles and industry professionals as their reference chassis noise reduction system.
