Synergistic Research MiG 4.0 Isolation Footers

Synergistic Research MiG 4.0

MiG 4.0 (Mechanical Interface Ground) is Synergistic Research's accessible-tier component isolation footer, sitting between the included MiG 3.0 and the flagship MiG SRX. Like MiG SRX, it replaces the uniform forged dome of earlier MiGs with a precision CNC-machined, variable-wall-thickness high-carbon steel resonator, designed to manage how mechanical energy propagates through the footer rather than simply absorbing it. MiG 4.0 is voiced to the same ULF bias frequency used across Synergistic Research's FEQ Carbon and other field-generating products. Two orientations offer different tuning: two footers "round side down" with one "round side up" for a focused, articulate presentation, or the reverse for a larger, more liquid presentation. As an authorized Synergistic Research dealer in Toronto, Canada, Vinyl Sound can help you decide between MiG 4.0 and MiG SRX for your system and budget.

Key Features

• CNC-machined, variable-wall-thickness resonator (vs. the uniform dome of MiG 3.0)
• Voiced to the same ULF bias used across FEQ Carbon and other Synergistic Research field products
• Dual tuning orientations: Pinpoint (focus/articulation) or Ambient (scale/liquidity)
• Sold as a set of 3
• 30-day money-back guarantee

Orientation Guide

• Pinpoint (2 round-side-down, 1 round-side-up) — sharper soundstage focus, tighter bass; best for digital streamers, PowerCells, and solid-state gear
• Ambient (2 round-side-up, 1 round-side-down) — expansive, layered soundstage with a warmer, more liquid presentation; best for DACs, phono stages, and tube-adjacent tastes

MiG 4.0 FAQ

How is MiG 4.0 different from MiG SRX?
MiG 4.0 and MiG SRX share the same variable-wall CNC-machined resonator concept, but MiG SRX is the higher tier, with three distinct UEF Metamaterial formulations (one per footer). MiG 4.0 is positioned as the more accessible option for rack-mounted components.

How is MiG 4.0 different from the included MiG 3.0?
MiG 3.0 uses a uniform forged dome with passive resonance behavior. MiG 4.0 uses a CNC-machined, variable-wall resonator voiced for ELF/ULF field integration with FEQ Carbon and other Synergistic Research field products.

Which orientation should I use?
Pinpoint for digital streamers, PowerCells, and solid-state gear where focus matters most. Ambient for DACs, phono stages, or when you want a warmer, more liquid presentation.
