M3 Platform

M3 Platform

The M3 Isolation base is our current reference level isolation solution. It significantly reduces the negative impact of structure-borne vibration on your audio component performance. It minimizes input vibration, provides significant levels of isolation, and properly controls residual energy.

This unique design utilizes six different materials to optimize stiffness, geometry, mass, and impedance characteristics.

Each material is carefully selected for optimum performance and functionality. The M3 Isolation Base also uses two different proprietary HRS elastomer formulations. The first was developed to maximize isolation efficiency, and the second was developed to control and eliminate residual energy.

A finely polished black granite contact plate is combined with two custom resonance control stages in a billet machined aircraft aluminum frame with a craftsmanship finish and black anodize coating. This exceptional design was created to offer maximum performance, cosmetic elegance, and a durable scratch resistant inlay design that will provide years of maintenance free service.

The M3 Isolation Base is produced in four standard sizes. Each size can be purchased in any of the three different load ranges to optimize component performance.

If one of standard sizes or load ranges does not fit your needs, HRS offers hundreds of custom designs for many different components including all large turntables and amplifiers. Please contact your local sales representative or Harmonic Resolution Systems for assistance with custom isolation bases for your components.
