MXR Audio Stand

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.

 

Fully adjustable shelf system (quantity and location) Load range of each shelf optimized for maximum performance Leveling system with locking feature for stability Infinite cable access (no vertical or horizontal beams) Structure design for optimum isolation base performance Unlimited expandability preserves initial investment

SRX Audio Stand
SXR-1921-3T2 frame with three S1 and two M3 Isolation Bases

The SXR Audio Stand was developed based on technical concepts and technology derived from our reference level MXR Audio Stand frames. The SXR frame system combined with Harmonic Resolution Systems isolation bases eliminates noise revealing a new level of musical performance. The modular frame concept is manufactured from billet-machined aircraft aluminum with a resonance control system. The highly acclaimed HRS isolation bases load directly into the SXR frame as the shelf system. The SXR frame optimizes isolation base performance while offering unique flexibility and functionality. The SXR frame system is completely modular and can be expanded vertically or horizontally at any time. It is available in a 1 bay (amp stand) configuration up to an infinite number of bays for larger systems. The SXR Audio Stand can be reconfigured, expanded or contracted at any time by acquiring the additional parts of the system needed to make the desired changes.

The SXR frame system contains two high frequency billet machined primary braces that support each shelf. The support braces vertical spacing is established based on the specified support structure length. Length can be specified for 6 inches, 8 inches, or 10 inches of usable shelf space at time of order. The shelf spacing can be changed in the future by changing the support structure length. 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 by adding or removing the required structural elements. The SXR is a very high performance system in a flexible, innovative, and cost effective design.
 

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 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
The HRS Analog Disk record weight is a highly innovative design that eliminates record groove noise revealing a new level of musical performance. It is manufactured from a proprietary polymer and billet-machined black anodized aircraft aluminum bonded together using a precision transfer mold with less than one thousandth of an inch tolerance for perfect alignment and balance. The weight and final polymer properties are based on years of development tests. The result is a design that performs equally well with high mass turntables and lighter weight suspension designs.
