Upgraded cables and an unswitched mains socket did it for me.

I don't have any switched sockets in the house.

Interesting comments from Nick (lurcher), 'elsewhere', about a possible technical explanation for the efficacy of your new mains lead, even though it's being used between the wall and your regenerator:

Kevin, does the mains lead you bought from David contain the DC blocker in question?Originally Posted by lurcher300b

It has his "bespoke filters" in the plugs, but there is no sign of a DC blocker sized box.

Ok, then could you ask David what the filters are designed to do, and if they address DC on the mains - or maybe there's something on his website about them you could link to?
Is the mains cable you bought from him on his website?

He won't give out details easily. It took me a while to find out what the cable was.
My mains regenerator converts AC to DC and back again. Prior to the mains regenerator my amps hummed. Since fitting it, they are silent, so the regenerator is taking care of the DC element.
I will have a look on his website and find something similar, as the cable I bought was not on there.

Ok, just trying to find out if what Nick said about the DC blocker is relevant to your cable. Let me know what you find.

It is probably close to this - https://www.mains-cables-r-us.co.uk/...ower-lead.html but you won't get much detail from the listing.
Obviously, I don't have a UK plug, or fuse...
Personally, I don't care what people elsewhere may say. If mains did not make a difference, why do regenerators and balanced mains units exist?
I have DC on my mains, my amp hummed. I used a DC blocker and it went away. The DC blocker "protected" one piece of kit, so I went for a mains regenerator which protects the lot.
No humming toroidals = happy Cagey.

Some Info from Mr Brook:
Kevin,
Your mains lead is simple, UP-OCC copper which is the best copper ever made for mains power leads, same as Marco uses in his ultimate mains leads just a different manufacturer of the cable, yours is Neotech, Marco's is Oyaide. The wire comes from the same factory, as Furukawa are the only company in the world who make UP-OCC copper as they own the machine it comes from!
The Neotech is quite special as it uses a hybrid of silver plated and pure OCC as well as a drain wire and foil shield to act as a faraday cage to keep mains noise at the plug end not the equipment end.
Add MCRU's bespoke cable filters which are small enough to fit inside the plug end and the IEC end to stop the individual conductors (live, neutral and earth from acting as aerials picking up radio waves).
The Furutech connectors on each end are cryo treated and also use very high grade copper.
The cable is covered in acoustic braiding.
DC blockers were not requested by Kevin even though it would make his mains regenerator sound even better, I work to budgets and the figure Kevin gave me would not allow for a DC blocker mains lead which sells at £450+
Almost every mains regenerator would benefit from a dc blocker as most are basically a large transformer which usually hum or buzz because of DC on the mains, Nick's design of DC blocker stops hum and because it blocks DC from entering the mains results in improved sound quality throughout the system.
