ISOLATION BASES 

"The...Brinkmann Balance turntable System... and HRS M3 Isolation Base is - with the exception of the Rockport System III - the best turntable system I've ever heard.”


Michael Fremer

M3 ISOLATION BASE


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 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.

  • 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 (M3-1719, M3-1921 sizes)

  AUDIO STANDS

There are two primary noise paths that degrade audio and video signal quality. There is the structure borne vibration that is traveling trough the structure and reaching the component and then there is the air borne path that is coming from the energy in the room traveling through the air to the component chassis directly.

The structural borne vibration is significantly reduced by use of Harmonic Resolution Systems audio stand frames and isolation bases. The air borne energy and resulting chassis noise is dramatically reduced by use of our Nimbus and Damping Plate Products.

The MXR Audio Stand frame (shown above) is Tthe HRS reference level frame system. This design is a result of nearly a decade of development and refinement by our engineers and craftsmen. It is manufacture using the latest technologies and finest materials available. Every MXR Audio Stand system is a work of art and science that provides a new level of performance and enjoyment to our customers.

The SXR Audio Stand frame (shown below) was developed based on the same engineering principles and concepts as the reference level MXR but it is executed in a different and innovative way that provides a great deal of performance at a lower price point that provides HRS performance to a wider range of systems. The innovative SXR frame design was also designed from the start to be capable of horizontal and vertical configuration. The SXR frame system provides excellent performance and features infinite configuration flexibility.

Review 6moons

MXR-1921-4V in walnut burl finish.
"A lot of equipment -- much of it good and a good deal of it better than that -- has graced my listening room since Mike Latvis… of Harmonic Resolution Systems came to my home several months ago…. Still, at the end of the review cycle, almost all of them have gone back from whence they came. Not so the HRS equipment rack; it's not going anywhere. In fact, as soon as I can scrape together the money, I intend to purchase another.”
(HRS Audio Stand Selected as Product of the Year.)”

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
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. The MXR Audio Stand was simply designed to be the last equipment stand you will ever purchase.
