Try using Ground Loop Isolator or Impedance plug (10-30 Ohm should be enough).
Thanks for the speedy reply as well as the suggestion, will try!
what would have your preference of the two?
If I choose a Ground Loop Isolator is there any value range I need to look for ?
last question would you place the this "device” directly after the Connect or just before the HIFI set?
I would be trying another receptacle and see what happens. It does sound like a ground wire issue. Use an extension cord and plug the connect into a different receptacle and see if that helps. The ground loop insulator would be plugged in first then the connect.

Im no expert in this topic, I just had similar issues with Sonos Ray where it was buzzing when connected to Audio Converter and long RCA cables. I used ground loop as far from soundbar as possible, but the noise was not cause by loop. Instead I decided to use Impedance Plug (30, 50, 75, 150 ohm). It worked perfectly but difference in sound was audible for me. Choosing 30 Ohm lowered the maximum volume by 15% and there was less bass.
First try to specify which issue you have. Try connecting all devices to the same extension cord, if you still hear the noise, try Ground Loop, if that doesn't help get a 30ohm impedance plug. If nothing helps it might be internal device issue.
Hi, with receptacle you mean another wall outlet I assume? would it have to be on a different fuse?
As to the ground loop insulator, my assumption was that it would go between Hifi set and Connect.
You seem to indicate it should go in the 230 v connecton?
Yes, plug it in to a receptacle in another area and see if your still getting the buzz sound. Yes to the other question so you plug in your connect after the ground loop. See if that gets rid of the buzzing sound as it must drive you crazy. Again good luck
If you have a cable box connected to the system, try disconnecting the cable feed from the street. Poorly grounded cable systems can cause hum. The cable system should be connected to the same ground point as the house power. Poor grounding increases the risk of lightning damage.
Although they can sometimes reduce ground loop hum, I’m not a fan of cheap hum eliminators. The most effective ground loop eliminators will use a transformer. The cheapest will use a couple capacitors that can impact audio quality.
Maybe try a breaker bar as well to see if that helps. Its always a good thing to have all your electronics plugged into a breaker bar to protect them for electrical surges as well as faulty wiring for whatever reason. I have my Sonos speakers connected to a Surge protector. Gives me piece of mind just in case as we never know.
