The biggest upgrade to electrical signal I’ve found is to have a dedicated electrical supply not from the fuse board run this as a radial supply with just the earth retuning to a earth spike in well watered part of the garden

I have a dedicated ring of 16 sockets for my audio system. This dedicated ring is protected by a Hager RCB consumer unit which is independent of the main consumer unit (using ELCBs) protecting the rest of the household electrics. The two consumer units are connected to the meter tails via a Henley block.
The incoming mains cable to my property uses the TN-S arrangement, and has a measured earth impedance of 0.3 Ohm.
Modern installations now use the TN-C-S (also known as Protective Multiple Earthing) arrangement, wherein the neutral and earth are combined, but they are separated out in the installation. Adding a separate earth spike, could under certain fault conditions in a neighbour's property which uses the same mains feed arrangement, be dangerous. Check to see which arrangement your incoming mains cable uses.

Was all carried out by a electrician who works for me, all signed of by NAPPIT and part P certificate. Thanks for the advise though.

My mains is a very old system (60s), which does connect -ve to earth, and is still legal. It has only fuses, but I don't think it compromises my Hi-Fi.

Lots of FUD flying around from folks that's never actually tried them...
Seems to be the way, is what it is.
After I had my hardwired balanced mains unit installed years back,
any thoughts pointing to "its just electricity, whats the beef?" rapidly dissolved.
Hence my (as it turns out happy) experimentation with better fuses.
My take?
They work, brilliantly,
but its system (not ear/brain interface) dependent.
Improvement is repeatable and easily demonstrated, its a genuine THING - but again system dependent.
Defo worth a subjective punt in your own system?
Price of entry is 50 quid on a Hifi Tuning Supreme 3 13A fuse.
In my experience, I wouldn't go any lower.
Too spicy?
Stay with the Bussmans and be happy.
Buy more music instead.
