The optimum configuration for each system is one Ground/Earth for the whole system. If a system has multiple Grounds/Earths, then it often creates unwanted ground loops. These systems will then have an annoying low-frequency hum (emitted from the speakers).
Current solutions either jeopardise (i) both safety and EMI shielding (e.g. cheater plug), or (ii) EMI shielding. And most are single country (US) uses only.
The GND Defender in the correct way, intelligently detects a ground loop and will cut the ground for that component.
With a GND Defender at the IEC power input, it will intelligently detect and remove the ground loop at the component.
If multiple ground loops exist, more than one GND Defender may be required. The GND Defender is smarter than the average ground lift. By a long way.
The GND Defender is not only at the cutting-edge in terms of technology but also safety:
Remember that best practice is to always keep at least one direct power cable connection.

Had a slight hum introduced into my system when I replaced solid state phono pre with all-tube unit. Not a huge believer in expensive power conditioners/regenerators, so I tried a few different power outlet combinations, with some success. But most significant improvement came from the iFi ground defender. My all-tube system, with efficient horn speakers, is now very quiet. Highly recommended.
This device successfully eliminated ground loop noise emanating from my PC! I was experiencing electrical noise coming through my studio monitors and this device attenuated all of the unwanted sound. I am currently using a desktop PC featuring an ASUS motherboard, and an external audio interface (UAD Apollo Twin X) with Yamaha HS8 speakers.

Perhaps it may work for others. But it did not work for me. Additionally, it messed with my PC power scheme, such that my PC would not shut off, when attempting to do so.
