That said, there are PCI and PCIe cards that might also eliminate the problem, as well provide more outputs for gaming and surround. The ones that I linked to are at the expensive end that, from experience, sound just like the plain wires that they replace across the entire audio range, except for the ground loop noise of course. This common audio-based gremlin can add an unpleasant hum and buzz to the sound of a PA installation, studio gear, or even your trusty stereo HiFi system.

The aim I suggest is to make the inductive loop lossy at 50 Hz and below whilst having minimum effect on higher audio frequencies… say from 100 Hz and higher. They’re also quite amusing, though I shan’t ruin the fun by telling you here, but it’s very “real life”. If you have nothing plugged into the inputs of the Arcam, does the buzzing still appear through your Naim system? Copper wire with gold connectors are the best combination; but again, don’t listen to the boutique audio sales propaganda. Their head, or maybe one time head as he now also has THAT Corporation, Bill Whitlock, is one of the world’s foremost experts on ground loops and Common Mode noise in systems.This power board is then plugged into an outlet on my first power board, which all my NAim equipment is connected to.

If you’re willing to part with a few Benjamins, you can assure yourself of pristine AC without ground-loop noise by using a line interactive UPS (uninterruptible power supply) or an isolation transformer. The inductive ground loop will pick the dominant magnetic field in your house, which is usually the mains frequency and its harmonics.If they are combined in a manufacturer’s product with no option to separate, it can cause interoperability issues between manufacturers and induced voltage ground loops. This requires the electrical power to go through a conversion to DC (direct current) and then back to AC, which will remove all the noise.
