The Audio Beat review of HRS’s RXR Audio Stand with R-Shelf
SXR Audio Stand
“In my opinion, the HRS rack is one of the greatest audio products ever manufactured.”
Stereophile, May 2011
SXR Audio Stand with S1 Isolation Base
“Adding the HRS SXR improved my system’s focus and low level resolution, and lowered its level of background noise. Consumers, and manufacturers who, despite the trouble and expense, schlep the heavy MXR racks to hi fi shows, had told me to expect a greater sense of overall system coherence and solidity. Even so, what I heard from the SXR was far more profound than anything I’d anticipated. I am buying a Harmonic Resolution Systems SXR rack.”
Stereophile, February 2009
“Harmonic Resolution Systems resonance control products now grace our reference room. The folks at HRS have brought their wealth of knowledge gathered throughout years of work in the commercial and government aerospace industries. They offer products ranging from damping plates to isolation shelves and full racks. They are the best that we have heard in 30+ years.”
Goodwins High End
“In the world of ultra-high end audio and video, only a few companies can lay claim to having created a component that has a performance advantage that leaves everything else in the dust. Harmonic Resolution’s MXR Audio Stand is in that select group. Nothing else comes close.”

M3 Isolation Base
“I reject the view that anything that is essential to the success of a music playback system can be called a “tweak.” No tweak I have ever introduced into my reference system has ever made a comparable improvement to the music or to the level of enjoyment I have gotton from it as the HRS M3 Isolation Base. It is a special product that far exceeded my expectations. With it, Harmonic Resolution Systems takes its place among the elite manufacturers of isolation devices. This will not be the last you hear from this company.”

“The Brinkmann Balance turntable System… and HRS M3 Isolation Base is – with the exception of the Rockport System III Serius – the best turntable system I’ve ever heard.”

“After hours and then days of listening, I came to the conclusion the the PiTracer not only sounded better sitting on top of the M3 platform, it sounded its very best. Its intrinsic character was discernible when it was resting on my Bright Star Townshend combo, but it wasn’t as pronounced — things sounded a little muffled or fuzzy in comparison. Not with the M3 underneath. The PiTracer sounded better than any CD transport I’ve heard.”
“The results of our listening test were instantaneous and a veritable ear opener. In addition to added body and improved imaging and focus, we all noted improved handling of dynamics, and a significant improvement in low-level information and inner detail.”
“With Harmonic Resolution Systems, nothing seems to have been left to chance, as they functioned well beyond our expectations.”

Damping Plate and Isolation Base
“We placed a couple of the “damping plates” on top of the housing and compared the resulting audio information. However, the A/B comparison was so one-side in favor of the Harmonic Resolution Systems that comparing is practically an unnecessary waste of time.”
“The plates rendered much better resolution across the audible frequency band, significantly improved imaging and focus and more body and weight to the sound.”

“Harmonic Resolution Systems’ products work, and work very well. They comprise a true system for addressing vibration and its deleterious effects on the performance of audio equipment — the most effective such system I’ve used.”

Analog Disk ADL
“Adding the Analog Disk to my unadorned turntable certainly produced results in excess of its cost. By this, I mean that you achieve a commensurate improvement would require spending a lot more money if you were to upgrade the cartridge, or the turntable itself.”

MIR Equipment Rack System
“Once you experience first-rate resonance control, you cannot go back.”
“The HRS rack is unrivalled in my experience as a means of securing an audio playback system against the deleterious consequences of the ‘noisy’ environment in which any system invariably resides.”
“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, president, chief engineer and designer of Harmonic Resolution Systems came to my home several months ago to set up his M1R equipment rack. The vast majority of those components have brought me hours of listening pleasure. 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.”

Damping Plates and Nimbus Products
“I would like to get another one of those 4.5 x 14.5 damping plate. I was messing around the other night and CAN’T BELIEVE how much better the DAC sounds with the top completely covered in them. I’m extremely happy with the plates I recently got. 35 of them total in the system. They really work and have made an incredible improvement. There really isn’t anywhere to go from here, unless I choose a completely different path.” -CD, WA
“Your Nimbus products are excellent!” -DT, Texas
“If these damping plates work as well as the others, I expect to wring even more resolution out of a system that has already gone well beyond anything I reasonably could have expected.”

Analog Disk Record Weight
“I can happily report that, yes, the HRS Analog Disk DOES make a difference”. “Identifiable increase in resolution around the “edges” of the voice… images became more “solid”. I didn’t even realize that there was this slight fraying in the notes until it was absent” “I tried playing the LP’s with the HRS Analog Disk, no clamp at all, and with after-market solid metal clamp made by your competitor” “Using the HRS Analog Disk was the best result” “I will be using it on every play from now on.”
M3 Isolation Bases and MXR Audio Stands
“I got the rest of the HRS order in and installed most of it last week. I am getting a detail in the soundstage I have not experienced before. The M3 Isolation Base under the turntable has elevated vinyl to another dimension.” -RH, Georgia
“I recently got my M3s for my mono blocks. As much as I was expecting a mighty fine product, nothing had prepared me for what I received. Stunning workmanship, the subtlety of the F-117, doing its work without crying out,’Look at me!’. Just superior isolation. So now I need a primmer on your Nimbus system. I already have the Damping Plates on my critical components.” -Will, Georgia
“I just wanted to say thanks for spending so much time on a late night last Friday with Sean and I. It was a remarkable experience. Not only is your product top shelf but it was one of the most enlightening listening experiences I’ve had in almost 15 years of HiFi. It was a truly educational experience, which goes right to the heart of why I enjoy this “hobby” of ours. If there was one thing negative about the whole experience it can only be that you have spoiled my ear! I can hardly stand to listen to my reference system without being reminded of what it can do and is not at this time!!” -CH, Illinois
“I owned a Zothecus rack, then the XYZ(brand intentionally removed from this version of quote) with carbon fiber shelves and then I auditioned the Harmonic Resolution Systems (HRS) M3 isolation bases, dampening plates and Nimbus footers. I then bought the new generation HRS MXR equipment stand in burled walnut finish (I literally just took delivery yesterday of the stand).
It is extremely attractive (my wife for the first time commented that I should put it out in my listening room versus inside my recessed equipment closet..), the shelves are adjustable, the wood work is flawless and, this is the best part, it radically reduces the harmful effects of air-borne and equipment-borne vibrations to a level I didn’t think was possible.
The really nice thing about the HRS system is that it is entirely modular allowing you to build it up piece by piece. For example, you can start with one isolation base for your CD player. You can put this isolation base on an existing shelf or rack. You can buy the dampening plates (which sit on top of the equipment) and Nimbus feet (which go under the equipment) piece by piece. I bought these in stages trying them on each piece of equipment to validate its impact before buying more. I ended up treating all of my components.
The isolation bases are designed so that they can sit on the floor or on another equipment rack. This is how I started and I ended up with 6 bases (dartzeel amplifier, 2 Hydras, CD12 player, dartzeel pre-amp, Linn Unidisk 1.1). For the best possible performance you can then buy the MXR frame (his second generation) and sit up to 4 isolation bases in the frame.
As a test, I just put one isolation base into the MXR frame last night and sat my Linn CD12 player on it. Before the frame arrived I had been listening to my CD12 on just an isolation base in a standard equipment cabinet. To tell you the truth, I was not expecting an audible improvement. I bought the rack mainly because of its beauty and precise engineering. I was totally blown away by the incremental sonic performance I got from my CD12 in the MXR frame. Everything became more fluid, musical and at the low end a new level of detail emerged such that I could follow every bass guitar pluck.
I realize this may sound a bit over the top and I am fortunate to have a dedicated and fully treated/tuned/calibrated listening room which fortunately and unfortunately lets me hear everything my system in doing – good and bad – but I was simply not prepared for the improvements the HRS has delivered in my system.
The HRS MXR is not cheap…. but it is some of the best money I have ever invested in my system. Inevitably, the other products I have tried over the past year of intense experimentation yielded some improvements in one part of the audio spectrum, but at the sacrifice of performance in another. The HRS is advertised to be one of the only vibration control systems that is “broadband” or across the entire spectrum. Based on my experience over the past 3-4 months it has lived up to its billing.
Bottom line, I strongly encourage all serious audiophiles to investigate these types of products before investing in expensive component upgrades. You may be very surprised at the performance your existing components can deliver if they are properly isolated from the destructive effects of air-borne and internally generated component-borne vibrations. I know I was. Every component I tried benefited with the most significant improvements being achieved from the source end on out (i.e. power line conditioner, CD player, pre-amp, amp in that order).
Buy on looks, but also buy based on your ears!”

“After further listening, all I can say is WOW! I just cannot believe the sonic difference. I will at some later point describe what I hear. I first am trying to figure out how to pry my jaw up from the floor! How much are the damping plates? What is your experience with them? Feel free to give me a call concerning these and their appropriate use.” -Bob, Indiana
“I intended to write this e-mail almost two weeks ago, but having assembled the MXR system I could hardly believe my ears, so I decided to wait until the initial enthusiasm had somehow disappeared.
But the enthusiasm is still there; or rather it is even more pronounced today: Clarity, micro dynamics and dynamic contrasts; space between instruments; the pace of the music – all these fundamental elements have greatly improved. The soundstage is deeper, wider and taller, and the harmonic structure of voices and instruments is now unbelievably real – and listening fatigue non-existing. Your MXR System is an accomplishment in the service of music and I congratulate you! Peter and I will recommend HRS to anyone who cares for music and not only for hifi.
And personally I like the thought that even the most expensive electronics cannot buy you perfection in sound reproduction. You really have to start with a solid basis!
PS. And on top there is the unrivalled build quality and finish!”

“Hi Mike. I love the rack and everyone who sees it (even if they can’t appreciate its capability) are mightily impressed not only with its build quality but its beauty. Thanks again for being so obsessive; it shows in the most positive way.
Thanks again for building such an excellent product and have a great weekend.” -JS, New Jersey
