Small, yet powerful ground control

What if you could significantly upgrade your audio system without changing any of your components? Simply connect your system to the Ground Block and you will hear things you've never heard before. Even the most sophisticated electronics are transformed with a dramatic reduction in noise. Music ushers forth from a jet black sonic background, with never before noticed detail. And modest components take on new refinement to perform far above their class with virtually every area of system performance being enhanced in dramatic and surprising ways. 

The Ground Block was engineered to improve ground performance on our new Atmosphere Series Level 2, 3, and 4 interconnects and speaker cables, as well as all SR products with external ground plane connections—like Tranquility Base isolation platforms, FEQ, and Atmosphere wave generators. Also recommended to connect all metal objects in your listening room, including, but not limited to, the metal frames of loudspeaker drivers and your audio rack.

The term “ground” refers to a connection to the Earth, which acts as a reservoir of charge. The high speed 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 Ground Block.

With optional connectivity cables the Ground Block also dramatically improves the performance of turntables, DACs, pre amps, power amps, digital devices or any component with an active or passive circuit inside. 

The Ground Block comes with the following cables as a standard:

1 piece (10 ft) standard wall ground wire to connect SR Ground Block to the wall outlet
4 pieces (4 ft) standard ground wires, to connect up to 2 pairs of SR Atmosphere or Galileo UEF Series Interconnects or Speaker Cables
2 pieces (8 ft) standard ground wires, enough to connect 1 pair of SR Atmosphere or Galileo UEF Series Interconnects or Speaker Cables

Available connections for other SR products with Ground Plane Technology:

Atmosphere: Acoustic Wave Generator
FEQ: Frequency Equalizer
Tranquility Base Products

Optional Basic and High Def connectivity ground cables are available for the following applications:

Turntables: connect to ground plug on turntable
Digital to Analog Converters (DACs): connect to spare digital input, output or chassis ground
Pre-Amplifiers: connect to spare analog input, output or chassis ground
Power Amplifiers: connect to spare analog input, output or chassis ground.
USB Devices: connect to spare USB Input, output or chassis ground
Any component with an active circuit inside: connect to spare Input, output or chassis ground
