SXR-1921-2V-Silver-w-S1s SXR Rack Blk



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 owner of the SXR system can also change the component spacing of any system. Standard shelf spacing can be specified at 6 inches, 8 inches, or 10 inches. This can also be changed in the future if the component size changes by ordering new strut lengths from your authorized Harmonic Resolution Systems sales agent.

Typical standard SXR frame configurations are shown below. This is a small sample of available configurations. Please consult your authorized HRS sales agent to determine the best configuration for your system needs. All dimensions below are for reference only and heights are based on 8′ shelf spacing.

Harmonic Resolution Systems manufacturers a variety of products designed to eliminate vibrations and control resonances. These include damping plates, nimbus puck like devices (both designed for controlling resonances of particular components); an analog record disk; isolation bases; and equipment racks/stands. I have a great deal of experience with HRS products. For several years I have owned the HRS, M1R equipment rack. Indeed after initially reviewing the rack upon its introduction in 2004, I bought two of the racks. (see my original review here). I had owned and tried several well-known racks prior to auditioning the M1R. The truth is I could not wait for the initial review period to end so that I could publish the review and then purchase the rack. Once I heard the difference the HRS rack made, there was simply no going back.

As a reviewer, I have had the good fortune of having a number of wonderful components in my home and over the years many of my friends in audio, the academy and the music world have passed through. In all this time, there are two components more than any others in my reference system that my guests have not merely lusted after, but put their money where their hearts resided: the Shindo 301 Garrard turntable system (I believe something like seven or eight visitors to my house have purchased one after hearing it here); and the HRS M1R (at least that many have purchased racks or individual isolation bases).
