Audio - the hobby that keeps on giving

I'm finding this totally fascinating.
After two decades of getting reasonable results in my old, acoustically and electrically challenged London apartment, I now have a room acoustic and quiet power grid in the depths of the country to die for.
Every system-wide impvt I install just reveals more and more, enhancing what I loved about my sound, and taking it to heights I never dreamed possible.
Balanced power, dedicated lines, now Sablon Elite power cords synergising w Stacore isolation platforms, enhanced by some Shun Mooks, and just today, a couple of SR Black fuses in my Zu sub amps.
I truly cannot believe the continued opening up of my sound, and I'm compelled to keep at it.
Other than a jump into the streamer/dac world for the first time, and a daydream of future purchase exotic tt/arm, component upgrades are behind me, I'm having so much fun discovering the limits of my current components.
Those limits? Limitless if my system impvts are anything to go by.

SoundA, I was living in Hackney E London, home of the £3 Latte, and £6 toastie, but as Ked will attest, my apartment acoustic was, er, appalling, which I only really realised on moving to the new room.
He lives in Central London, maybe he can tell you how to make a silk purse out of a sow's ear.

Adyc, when I was in London, we ran a real time analyser, and indeed voltage fluctuated +/- 10% from moment to moment.
Crazy.
The moment installed balanced power, this reduced to +/- 0.25%.
No exaggeration.
I'm the country, w'out the transformer, the fluctuation was down to +/- 1%.
With the transformer, it didn't vary at all over a fifteen minute sample period.
Additionally, my ground impedance in London was v high, can't remember the figure, maybe >100Ohms.
Here, it's under 5 if I recall correctly.

Micro, I really don't know
Google www.one4power.co.uk and look for "Westwick 8K" balanced power transformer, maybe info is there.
