Synergistic Research Tranquility Base UEF
Best isolation platform for audiophiles seeking a lower noise floor.
The Synergistic Research Tranquility Base Carbon elevates audio component isolation with its advanced design. Featuring a chassis that is 50% slimmer and 80% more rigid than previous models, it incorporates a carbon fiber top for superior vibration response. This platform utilizes patent-pending EM Cell technology and internal UEF Technology to condition the signal environment at the source. The result is a significantly lowered noise floor, leading to improved dynamics, enhanced soundstaging, and smoother high frequencies. It includes high-value MiG 3.0 isolation footers for added performance.

What customers say
Audiophiles consistently describe the Tranquility Base as a transformative component, not just an accessory. The core theme is profound sonic improvement, primarily through a dramatic lowering of the system noise floor, resulting in blacker backgrounds and enhanced micro-dynamics. Users frequently note significant gains in soundstage depth, width, and precise image placement. The base seems to unlock the full potential of placed components, yielding a more natural timbre and better transient response. While the premium price is acknowledged as a major investment, purchasers overwhelmingly agree the magnitude of the sonic benefits justifies the cost. It is viewed as an essential foundation for achieving state-of-the-art audio reproduction, delivering synergistic system enhancement.
Know before you buy
Unlike a passive shelf, the Tranquility Base uses active EM Cell and UEF technology to condition the electromagnetic environment around your components. It actively lowers the noise floor at the source, which provides a level of clarity and dynamic improvement that traditional isolation materials cannot achieve.
Yes, the unit requires power to energize its internal EM Cell technology. It comes with a single lead MPC power supply that connects to the base to facilitate the signal conditioning process.
While the MiG 3.0 footers are included to optimize the performance of the Tranquility Base, they are standalone isolation devices. You can experiment with them under other components, though they are specifically tuned to complement the base's vibration response.
The choice depends entirely on the footprint of your audio component. The standard Carbon measures 18.5 x 16 inches, while the XL offers a larger 20 x 23.25-inch surface area for oversized amplifiers or large-chassis source components.
The base is designed to be exceptionally slim at only 0.75 inches thick, making it easy to integrate into most existing rack configurations without requiring significant shelf adjustments. Its low profile ensures it remains unobtrusive while providing a rigid, carbon-fiber-topped foundation.
You will likely notice a quieter background, which allows for better micro-dynamics and a more defined soundstage. High frequencies often sound smoother and less fatiguing because the base effectively reduces electromagnetic interference that can cause subtle distortion.
