What grounding does, and what it does not
Grounding products give noise somewhere to go. They connect to the earth points, unused inputs or chassis of your equipment and draw high frequency noise away to a separate box or termination. This is a signal level treatment, which is why it sits in Hi-Fi Essentials rather than under Power.
Be clear about what it is not. A grounding box is not a mains conditioner, does not filter the incoming supply, and is not a substitute for sorting out a genuine earth loop. If you have audible hum, find the loop first. Grounding products address the noise floor, not faults.
Opinion divides sharply here and we will not pretend otherwise. Listeners who report a difference usually describe a quieter background and more separation between instruments rather than a change in tonal balance, and the effect tends to be more noticeable on systems with several digital components sharing a rack. If you are curious, start with one connection to the component you suspect is noisiest and add from there rather than treating everything at once.

If you can hear a consistent hum coming through your speakers, whether playing music or when idle, then you may have multiple ground/earth connections in your system causing a ground loop. This ground loop can be fiddly to fix, however, iFi have come along with an intelligent solution to help solve this issue. Enter the GND Defender! By using a specially designed AI Ground Detection, the GND Defender can automatically disconnect the ground on your device if there is a ground loop, eliminating the low hum through your speakers. But it does not stop there, the GND Defender can even reinstate the ground connection to pass current if any faults are detected in your system. This ensures a safety fallback to help protect your equipment.
