Active Ground Block SX - Sky High Performance starts at Ground.

The new Active Ground Block SX is a technological trickle-down of our cost-no-object Galileo Active Ground Block plus new technologies that were not developed when we first engineered the Galileo Active Ground Block. First, we start with a Galileo-style chassis machined from a solid billet of aluminum plus carbon fiber to lower distortion related to mechanical vibration. Next, we developed a power supply with technology and lessons learned from our LPS or Linear Power Supply development program for the lowest noise floor of any Active Ground Block to date. We then dialed up the performance of our ULF bias of ground by introducing duel harmonics of the Schuman Resonance instead of just one with technology developed for our upcoming 2023 Galileo PowerCell. We also focused on making the new Active Ground Block SX more practical than the popular Active Ground Block SE by upping the number of ground points from 22 to 32. This means you can ground an additional ten components, cable shields, system racks, or anything in your system made from a conductive material to maximize system performance. Finally, audition the Active Ground Block SX in your system and discover why we say ultimate performance starts at ground level.

Robert I. ★★★★★

I wasn’t sure if a ground block could make a difference, but after plugging in this pre-order unit, imaging tightened up and background hiss I didn’t even notice before just vanished. The build feels solid, and the simple installation took maybe two minutes.

Robert ★★★★★

The noise floor in my system dropped so noticeably after hooking this up that I went back and re-checked all my connections, thinking something had changed. The ground block itself feels rock solid, and the difference it makes to the quietness between tracks is genuinely striking.

Christopher ★★★★★

The pre-order wait was a bit long, but the Active Ground Block SX's trickle-down tech from their top-tier models really cleaned up the noise floor in my system. It made the stage sound noticeably deeper and more focused.
