Aerospace vibration engineering for the audio rack, designed and built in Buffalo, New York since 1999.

Michael P. Latvis Jr. trained as a mechanical engineer at New Hampshire Technical Institute and Rochester Institute of Technology and spent his first career making things stop shaking. From 1986 to 1993 he was a senior product engineer at Lord Corporation, a vibration-isolation company, working on helicopter components for Sikorsky including the Black Hawk; he then managed a vibration-isolation products group whose projects included Boeing, Airbus and Lockheed Martin, with earlier work in nuclear-power quality assurance and later work on missile-defense systems. His interest in music had begun with the trumpet. He started by designing isolation devices for himself and friends, applying the tools of his trade, finite-element analysis and proprietary polymers, to the problem of a phono cartridge that, as he later put it, behaves like a strain gauge converting motion into signal. Harmonic Resolution Systems was founded in Buffalo, New York; the company dates its founding to 1999, and Latvis himself has said 2000. It has been in Buffalo, under his direction, ever since.

The first products reached reviewers in 2004. Marc Mickelson reviewed the M3 Isolation Base in SoundStage that June, at $1,345 to $1,965 depending on size: a polished granite slab in a frame machined from a single aluminum block, decoupled by polymer pads and built from three proprietary polymers and two metals, and he found the increased focus and authority were not subtle. The M1R rack, at about $9,000, arrived the same year, and the MXR replaced it as the flagship frame. In 2008 came the SXR Audio Stand, the design that still defines the company: fully modular, no fixed frame, eleven part types, every shelf the same price, a four-shelf frame at $4,995 and an M3 base at $2,395. Michael Fremer reviewed it in Stereophile in February 2009 and found it improved his system's focus and low-level resolution and lowered its background noise; it has stayed in Recommended Components since. By then the Nimbus couplers and the Damping Plates, the chassis-noise half of the system, were in the range alongside the S1 base.

The M3X succeeded the M3 by 2013, reviewed by Wojciech Pacuła in Positive Feedback. At the end of 2015 HRS added a lower-priced tier, the RXR frame and R-Shelf with the R3X base, which Roy Gregory reviewed in The Audio Beat, and two new ideas at once: the Vortex chassis footer and the G-series grounding feet that let a base drain energy rather than isolate. The same year Latvis filed the provisional applications for US Patent 10,045,615, a modular and reconfigurable high-performance audio stand, issued in 2018. A prototype of the stand it covered, the VXR, was shown at CES 2016, and the production VXR was unveiled at CES 2017 as the new top of the line, a four-shelf version at $25,000 to $31,000, alongside the S3 base at $2,195 replacing the S1; Latvis's description to Stereophile was that it is infinitely changeable. The M3X2, the reference base with two internal resonance-control stages, had replaced the M3X by December 2018, when Danny Kaey reviewed an SXR with M3X2 and S3 bases in Fidelity and called it the single best rack and isolation system he had come across.

The entry level was rebuilt next. The E1 base, from $1,095, and custom VXR amplifier stands were announced for AXPONA 2020. In September 2021 Jacob Heilbrunn reviewed a VXR built for a TechDAS Air Force Zero turntable, with Vortex, Helix and Damping Plates, in The Absolute Sound, and the VXR with M3X2 bases became a TAS Editors' Choice. In July 2022 HRS launched the EXR Audio Stand System, its lowest-priced stand, with an asymmetrical four-leg frame and shelves that are themselves damped plinths, so no separate bases are needed; it was patented as US 11,751,682 in 2023, and Christiaan Punter bought two three-level EXRs after reviewing it. In December 2022 the E1X replaced the E1 at $1,575, with the Vortex's and Helix's patent, US 10,187,712, already behind the couplers; StereoNET gave the E1X an Applause Award in November 2024. The RXR, MXR, E1, S1 and the Analog Disk clamp moved to the legacy list.

In June 2025 the EXR gained vertical, tiered and horizontal configurations and a double-wide EXRD with a continuous 42-inch shelf. In October Robert Harley reviewed a three-level VXR with M3X2 bases, $37,245 and 452 pounds, in The Absolute Sound, calling it a revelation in engineering, configurability, future flexibility, build quality and sonic performance; it received a 2025 Golden Ear Award and, on December 11, 2025, was named The Absolute Sound's Product of the Year. The same month the Vortex and Helix were revised with a reduced thread fit and a $130 upgrade for existing owners. In 2026 HRS added six custom amplifier-stand options, single-, double- and triple-wide EXRs, and dealer-configured custom bases. The company remains at 2495 Main Street in Buffalo, with Latvis as chief engineer, Eric Krone running production and Emily McArdle coordinating sales, every product manufactured in the United States, inspected, and approved by a listening panel before release. Its own line is that performance comes first at HRS.
