The Chord Company GroundARAY Signal Ground is designed to be connected to any unused socket on a component, it then very efficiently absorbs noise on the signal ground, leading to very noticeable improvements in overall performance. You can add as many of these to a system as you like, improving performance more and more with each one you add! A great feature, as you have the option of adding more and more to their systems. It is available with many different connection options – XLR (male or female) RCA, USB, HDMI, 5 pin DIN, BNC & RJ45
Chord have found when deploying the GroundARAY, it is best to start at the source. In many cases these days that would actually be the data switch. For example from demonstrations Chord have done recently, adding the RJ45 model to the English Electric 8Switch or 16Switch makes a marked improvement. You can then add more to your streamer, other source components, DAC, preamp and so on.
You can also add multiple GroundARAYs to a single component and get a significant upgrade in performance from doing this.
