HRS M3 Isolation Bases

The M3 Isolation base is Harmonic Resolutions (HRS) 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 used in the HRS M3 design to directly support your audio component providing exceptional beauty and years of scratch resistant service. The M3 Isolation Base is produced in four standard sizes. Each size can be purchased in any of the four different load ranges to optimize component performance.
The standard color is black, but inquires for custom colors, sizes, and load ranges are welcome.

 Broadband noise reduction system maximizes performance
 Highly effective on wide range of surfaces and structures
 Low profile compact design minimizes space requirements
 Standard and custom sizes ensure full system integration
 Integrates directly into HRS audio stands without modification
 Selection assistance from extensive HRS application library

HRS Audio Stands

The MXR Audio Stand is an industry leading design that eliminates noise revealing a new level of musical performance. The frame itself is manufactured from six different materials including billet-machined aircraft aluminums and exotic finishes over a composite inner frame structure. The highly acclaimed HRS isolation bases load directly into the MXR frame as the shelf system. The MXR frame optimizes isolation base performance while offering unique flexibility and functionality. It is the last system you will ever need.

The MXR Audio Stand comes in these standard finishes: Mahogany, Walnut Burl, Piano Black, and other custom exotic wood and automotive finishes.
Custom rack systems configurations, including side by side systems, are currently available. Please contact your local dealer or HRS for more information.
Note: Double wide systems available for each model with twice as many isolation bases.
Add 23" width for 1719 models and 25" width for 1921 models.
Four ultra high frequency billet machined brackets support each shelf. The brackets are adjustable vertically allowing you to select ideal shelf spacing for your system. Regardless of the final shelf location you still will have infinite cable access because there are no front or rear braces to the main structure. You can also add or remove a shelf at any time without any modification to the rack structure or detracting in any way from its exceptional performance or beauty.
Because each shelf is a HRS isolation base they can be used in the MXR Audio Stand, on top of any other equipment rack shelf or on your floor as an amplifier stand making the system very versatile to future changes. The MXR Audio Stand was simply designed to be the last equipment stand you will ever purchase.

HRS Damping Plate MKII
Review soundstage

 The HRS Damping Plate MKII significantly reduces the negative impact of air-borne vibration and residual structural-borne vibration on your audio or video component performance. The HRS Damping Plate should be placed directly on top of an electronic component chassis with the soft side (a custom formulated elastomer) of the damping plate in contact with the electronic component chassis surface. The greater the surface area covered by the damping plates, the greater the improvement in audio/video performance.

HRS Damping Plates MKII are produced in various sizes to allow you to create the optimum configuration for your component(s). All visible surfaces are made from a precision machined billet aircraft aluminum with a black anodize finish.

The HRS Damping Plate is also effective at reducing radiated cabinet energy from the top of a number of speaker cabinets.
 

HRS Nimbus System
The HRS 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.

• Broadband noise reduction design maximizes performance
• Effective on electronic chassis and speaker cabinets
• Selection of sizes and heights allows system optimization
• Proprietary polymers optimized from years of

• High grip design creates very stable system
• Separate Nimbus elements maximizes configuration flexibility

- The all polymer Nimbus Coupler

- An all metallic Nimbus Spacer

The HRS Nimbus system is placed directly on the shelf supporting your component with one of the all polymer Nimbus couplers in contact with the surface of the shelf and another in direct contact with the bottom chassis of the component. The Nimbus spacer is selected to give you the desired height of the system. Review Soundstage
 

HRS Analog Disk
