The heart of each serious A/V system

By cleaning up your system’s ground connection you hear an improvement in soundstage height, depth and width thanks to a lower noise floor. Soundstage scale is improved with richer tonal density especially at the edges of your sound field. Image outlines are brought into clearer focus while musicality and overall system refinement are greatly improved. As a matter of fact, all audiophile properties benefit noticably from it. Video clearly wins in sharpness and focus and is far more natural. No other type of accessory will have such an impact.

The term “ground” refers to a connection to the Earth, which acts as a reservoir of charge. The high speed, SR Active Ground Block provides a conductive path for this ground, separate from the normal current-carrying path of your components, which under certain conditions can add up to 10 dB of noise if poorly designed! The ground path with the least resistance is the best path to Earth, and there is no better ground path for your components than the SR Active Ground Block. 

The new Active Ground Block takes the UEF Ground Filter from our original SR Ground Block and adds an active ULF Field Generator. Benefits include a noticeable increase in deep bass power and weight, a more holographic sound field, smoother high frequencies with greater extension and ‘air’, a more present and layered mid range, increased tonal density with an apparent increase in resolution; it’s like going from a standard resolution Redbook file to Double DSD, the improvement is that dramatic. Nearly every aspect of system performance is transformed over the original; in fact, the difference between the new Active Ground Block and our original SR Ground Block is greater than the difference between the original Ground Block and no ground filter at all!

How does it work? It all starts with 44 star ground points to reduce component to component ground inductance. That’s 44 ground connections to the original’s 18. You can ground your entire system including all components, a full loom of SR cable shields, and even equipment racks, computer hard drives, absolutely everything in your system can be grounded to one SR Active Ground Block. Filtration is handled by a UEF Ground Filter that’s 3 times the size of the original’s UEF Ground Filter and this translates into 3 times the performance of the passive ground filter alone. To this we add an Active ULF Field generator as found in our PowerCell 12 UEF which re-clocks high-frequency ground noise to the Earth’s Schumann resonance as well as noise generated inside connected components at the circuit level, so each connected component’s performance is fundamentally transformed at the source. And the Active Ground Filter is the only ground filter in the world to use such a filter mechanism for a performance unlike anything you’ve ever experienced. Stepping up to the Active Ground Block SE replaces the standard model’s passive Quantum Black Power Cord with a specially modified Atmosphere Level 2 Active power cord equipped with Galileo UEF Quantum Gold and Silver Filters that give you two distinctive sonic options to the overall sound of your system. With the included Galileo UEF filters you perfectly tailor the sound of the Active Ground Block SE to match your system, or leave the Galileo UEF Filters disconnected, the choice is yours. 

When using Atmosphere Interconnects and Speaker Cables Levels 2–4, the Active Ground Block applies our UEF technology to the directly to the ground path's shields lowering the noise floor and ramping up overall performance.
