About Synergistic Research Tranquility Linear Power Supply
Synergistic Research Tranquility Linear Power Supply Key Features:
- State-of-the-Art Design – Built with a solid billet aircraft aluminum chassis and carbon fiber top to manage heat and minimize mechanical resonance.
- Advanced EM Conditioning – Patented Active EM Cell with UEF Technology lowers the system noise floor, expanding soundstage and improving dynamic range.
- Optimized Power Delivery – Incorporates high-performance transformers and regulated DC circuits conditioned with SRX Long Duration High Voltage techniques for maximum clarity and resolution.
- System-Wide Performance Upgrade – Enhances Tranquility Bases, Tranquility Pods, and FEQ Carbon components with tighter bass, extended highs, and greater musicality.
- Optional Grounding – Features direct connection to an SR Active Ground Block (sold separately)
Product Description:
High-resolution audio begins at the wall and continues through each component’s power supply. In developing the Limited Edition Galileo SX PowerCell for 2021, Synergistic Research started with an entirely new regulated power supply incorporating the latest UEF Technology. Multiple transformer constructions and materials, including C Core and toroidal designs, were compared in double-blind listening tests. Surprisingly, the best toroidal transformers sounded more spatially closed compared to top-tier C Core transformers. The transformer windings were then conditioned using the Long Duration High Voltage process first developed for the flagship SRX cable loom. Various DC rectification schemes and capacitors were also tested and treated with UEF technology until a power supply was perfected, elevating the Galileo SX PowerCell to state-of-the-art performance. Building on this, new power supplies for the Tranquility Bases, Tranquility Pods, and FEQ Carbon were engineered using Galileo SX technology, housed in a solid billet aircraft aluminum chassis for thermal management, topped with carbon fiber to disrupt mechanical resonance from stereo speakers.

Solid Billet Aluminum Chassis with Active EM Conditioning
With a Tranquility UEF Power Supply powering Tranquility Bases and Tranquility Pods, the system’s soundstage expands in size and scale. Low frequencies gain impact and control, while overall resolution improves due to a lower system noise floor. The result is a system-wide upgrade, enhancing dynamic range and refinement across all SR components for a noticeable improvement in overall performance. Available for risk-free in-home audition.
SR Ground Block—This goes to 11
The Tranquility UEF LPS includes a direct ground connection, allowing optional grounding to an SR Active Ground Block (sold separately). This further lowers the system’s noise floor, enhancing performance across all active SR components.
