Synergistic Research MiG SX Mechanical Interface Grounding Footers, Set of 3

Synergistic Research MiG SX Footers Key Features: 

• Advanced Construction – Forged high-carbon steel MiG resonator with a precision three-piece chassis of aircraft aluminum and carbon fiber, optimizing vibration transfer and resonance control.
• UEF-Tuned Components – Incorporates a UEF tuning element, specialized tuning disc, and carbon-tungsten ball bearings for precise energy management and enhanced sonic clarity.
• Customizable Tuning – Two placement options, Pinpoint (focused imaging, tighter bass) and Ambient (layered soundstage, fuller bass), allow component-specific optimization.
• Auditioned Performance – Iteratively tested internal materials and configurations deliver balanced, natural sound with holographic imaging and tunable soundstage.

Product Description: 

MiG SX footers are the latest evolution of Synergistic Research’s original MiG footers, first developed in 2008. Each unit features a specially tuned MiG resonator forged from high-carbon steel, combined with a precision-machined three-piece chassis of aircraft aluminum and carbon fiber. Vibrations are managed through a specially engineered tuning disc and a UEF tuning element into carbon-tungsten ball bearings, optimizing energy transfer and resonance control.

For a bespoke system match, MiG SX offers two placement options—Ambient and Pin-Point—that allow users to fine-tune component resonance on a per-component basis. Installed in a system, MiG SX enhances nearly every aspect of performance, delivering a more massive and dense sound field, improved imaging, tighter and deeper bass, extended high frequencies, clearer midrange, and more precise layering of musical images. Synergistic Research stands behind MiG SX with a money-back guarantee, confident in the dramatic improvement it brings to system performance.

Design notes from Lead Designer Ted Denney describe the evolution of the MiG SX footers from the original MiG design. Denney aimed to preserve the signature expansive soundstage and custom-voicing ability of the original MiGs while incorporating the precision and refinement found in the world’s most expensive multi-component isolation footers.

To achieve this, the forged high-carbon steel MiG resonator was retuned, and a three-piece CNC-machined chassis of aircraft aluminum and carbon fiber was developed to optimize mechanical vibration transfer. Vibrations are further managed via a specially designed tuning disc, a UEF tuning element, and carbon-tungsten ball bearings. These internal elements were iteratively tested—materials for the bearings and tuning components (stainless steel, brass, aluminum, carbon-tungsten) were evaluated through double-blind listening tests to determine the combination yielding the most precise, balanced, and natural sound.

Denney notes that soft tuning rings overdamped the sound, while different metals imparted distinct audible signatures. The final MiG SX design achieves precise imaging, exceptional clarity, and an expansive, tunable soundstage while maintaining the holographic and versatile qualities of the original MiGs. By allowing independent tuning of each internal element, MiG SX delivers a level of performance and refinement unattainable through theory alone, creating the most versatile and balanced component footer Synergistic Research has ever produced.

Tuning Options

Pinpoint

When configured with two MiG SX footers “Round Side Down” and one “Round Side Up” under a component, the setup sharpens soundstage focus, provides pinpoint image placement, and tightens bass response. This arrangement is particularly effective under PowerCell line conditioners, hard drives, digital servers, or any component where a highly focused, less ambient presentation is desired. Users will often find that most components favor one orientation while at least one benefits from the opposite configuration, allowing the system to take advantage of both sonic characteristics. For optimal results, Synergistic Research strongly recommends auditioning both configurations on a component-by-component basis to determine which arrangement sounds best for each component.

Ambient

When configured with two MiG SX footers “Round Side Up” and one “Round Side Down” under a component, the setup produces a more ambient, layered sound with fuller bass and softer, more rounded image presentation. This placement is particularly well-suited for those who prefer a liquid, musical presentation or a vacuum tube–like character, especially when paired with solid-state phono preamps and DACs. As with the alternate configuration, most users will find that while one balance is preferred overall, at least one component benefits from the opposite orientation, offering the advantages of both approaches. Synergistic Research strongly recommends comparing both configurations on a component-by-component basis to determine the optimal arrangement for each component in your system.
