• Product Overview – The Synergistic Research Active Ground Block SE, released in 2017, provides an active DC-biased grounding network that dramatically lowers system noise floors, improving clarity, microdetail, and dynamic contrast in high-resolution audio setups.
• Active Grounding Technology – Its patented UEF filtering and active biasing circuitry reduce high-frequency noise and distortive ground interactions, enhancing spatial realism, image separation, and low-level resolution across both analog and digital components.
• System Integration – The Synergistic Research Active Ground Block SE offers multiple grounding outputs to accommodate DACs, preamps, servers, switches, and amplifiers, expanding performance benefits across the entire system with consistent sonic refinement.
• Build & Performance – Heavy shielding, precision internal layout, and upgraded SE-level power supply contribute to significantly reduced EMI/RFI contamination, delivering a cleaner and more holographic soundstage.
• Dimensions – Approx. 254 mm (W) × 76 mm (H) × 203 mm (D), compact enough for tight rack placements while offering robust ground connectivity.
• Weight – Roughly 2.5 kg, with a solid chassis that minimizes vibration and supports stable grounding performance.
The S$4,280 asking price for this like-new Synergistic Research Active Ground Block SE is fair but ambitious, sitting well above the median of S$1,910 from 95 recent SGD listings and far exceeding the 75th percentile of S$7,060 only if you misread the data; actually, it is below the 75th percentile but significantly above the median, placing it in the upper-middle tier of the used market rather than a bargain territory. Given the unit is listed as like-new, the price reflects premium condition rather than a deep discount, making it a solid option for buyers who prioritize original-owner quality over hitting the lowest possible used price.
This active ground block is well-regarded for its ability to reduce ground inductance across up to 44 devices via its copper bus bar, offering a scalable upgrade over passive blocks by tripling the UEF filter size and supporting nearly 2.5 times more devices. Its aircraft-grade aluminum chassis and active grounding design make it a meaningful upgrade for serious systems, and the like-new condition implies minimal wear with likely full functionality—making this a worthwhile buy for enthusiasts ready to invest in top-tier grounding without waiting for a rare, cheaper find.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
