    I think I have found the culprit.
    It may be a network cable which I quickly threw behind the furniture when my wifi stopped working mid meeting.
    Either that or a ferrite I put on a power cable.

    Not heard the buzz for a while.

    Weekend job is to dress the cables as best as possible.

    There has been an interesting twist to this tale.
    The “smart meter” feeding my house had been invaded by ants, which caused a problem.
    This was replaced, only to find a dodgy connector on the telegraph pole connector. This has just been sorted.

    The outcome? No hum/Buzz, and I am almost at the point of believing that my system sounds better today than it has for the last few days.

    True…
    I have to say that they were very efficient in sorting the problem. Less than 10 hours to reporting the issue to it being fixed.
    I don’t think I have ever heard of that happening in the U.K.?

    It seems I wasted €10 on ferrites, but I am glad I did not buy one of the mains regenerators I looked at.

    As posted elsewhere, mine no longer makes any noise.

    The hum/buzz came back at a lower level last night, so thanks to Grant's reminder, I have plugged the AG1500 back into my system.
    Silence is golden.

    I just need to find the feet for it now, as it is now stood on end next to my rack, and I don't want it falling over.

    Having no electricity is a bit of an inconvenience so I gave an “ant box” to the guys who changed the meter to put in the meter box. I didn’t want a “smart meter” and there was nothing wrong with the old one. However, it makes it easier for the electricity companies to collect the data and bill us. They also inject more noise on the mains, and every house has one.
