Synergistic Research Galileo SX Active Ground Block MKII

Synergistic Research Galileo SX Active Ground Block MKII

The Galileo SX Ground Block MkII is Synergistic Research's reference active audio grounding hub, designed to connect and condition the signal-ground environment of demanding multi-component hi-fi systems. It combines active electromagnetic cells, an advanced multi-setting ULF generator and extensive ground connectivity in a substantial aluminium/carbon-fibre chassis.

Manufacturer technology and design

Synergistic Research has re-engineered this model with technology developed for its high-end PowerCell conditioners. Two active folded electromagnetic cells work alongside a flat ground-plane cell, with a purpose-built linear power supply and dual-channel ULF generator. Four selectable bias programmes — Purple, Blue, Red and Green — allow the listener to choose the manufacturer's preferred presentation for the system. The substantial connection array supports compatible cables, conditioners, analogue sources, DACs, amplification and other approved equipment.
