The M3X2 Isolation Base is the latest generation of reference level Isolation Bases from Harmonic Resolution Systems. It results from more than a decade of research and development to achieve true reference-level audio system performance. The M3X2 is manufactured from 70+ parts and six different materials, including two proprietary polymers, billet machined aircraft aluminum housing and polished black granite.

The HRS Nimbus System incorporates a highly effective design to eliminate component chassis noise, revealing a new level of musical performance. These products 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 special system is utilized by audiophiles and industry professionals as their reference chassis noise reduction system.
