As a general rule no box should have more than one connection to ground, though there can be exceptions. In cases where you’re unable to swap out cables or electronics (this is pretty common when working on someone else’s system or when they cannot afford to pay labor costs it may take to resolve it otherwise. Then I have an expensive power for my Linn and phono pre-amplifier, Phono power supply Lingo 4 power supply.

It’s not for tensile strength, it’s to block incoming and outgoing RFI (radio frequency interference). If you've ever noticed a hum coming through the speakers in a system that includes a TV tuner - or any piece of equipment that connects to an aerial - it could be because there's a ground loop. If your speakers are making a humming or buzzing noise then you quite likely have a ground loop issue.

Compared to a Jensen datasheet that shows a response graph from DC to daylight that is unnoticeably flat from 20Hz to 20kHz. En faisant des recherches j’ai réalisé que l’écran était le seul appareil disposant d’un prise à la terre sur le setup et de ce fait pouvait créer des boucles de masses qui sont devenues audibles (et insupportables) j’ai commandé sans grand espoir ce petit boîtier qui a complètement éliminé le sifflement et même les quelques souffles / grésillements (peu audibles à l’origine) que j’avais aussi avant. There are definitely times when it’s just not practical to avoid using a ground loop isolator or you simply can’t find another way to solve your noise problem.

Any combination of the approaches shown above should eliminate all the noise that’s not inherent in your audio system, as well as some you might have thought was inherent. And this ground loop isolator is designed to be used in conjunction with a audio system for an easy, hasslefree installation. The other rule for wires is not looping antenna signal cables (twin-lead), which tends to induce the same noise by making them antennas themselves. Internal audio solutions, especially those that reside on a computer’s motherboard, are susceptible to all sorts of line noise and electromagnetic interference that can’t be eliminated.I have used optocoupler and dc-dc isolators before, but I'm not sure how I should connect them in this context. I would definitely want to know that the reviewer has some sort of background in electronics and magnetics - which some of them do, of course. And ideally a single core, or if using one core of multi core cable ensure the others are cut short with no wire protruding anywhere where it could with movement reach the other connectors. When the system is up and running, I can hear a very faint hum/buzz from the speaker, mostly from the tweeter, so it is a high frequency.
