You're wrong again, that's not what it's about.
The detachable figure-of-eight mains connection allowed for system matching.
(All mainstream hardware OEM's from Arcam, through Philips/Marantz to Sony/
Technics adopted it through 80's into early 90's)
Because you didn't know about it (or the numbskulls of the clique) doesn't
mean that hardware with capability to invert polarity via such a mains
interface
and resulted in dramatic sonic differences depending on polarity to PSU,
well...
Because you (and the clique) are clueless on the subject doesn't mean it
isn't
fact and established. When the "powers that be" at head office put you right
on the matter I expect you to post online your back-tracking whimper.
You have my email, if/when you ever hit London, let me know and I'll demo a
whole heap of hardware that will open your eyes and educate you.
You have turned out to be a major disappointment, it maybe time you retired?

I don't claim to know anything for sure about figure of eight mains
leads, or the PSUs powered by them, although I've always been vaguely
distrustful of anything without an earth, especially when they give
off electric shocks, as much modern audio, video, and IT equipment
does.

However, what I do know is this. If you're going to criticise others
who have an established position, you have to be certain that your
argument is lucid and makes sense, both linguistically and logically.
Yours does not, for example ...

An isolating transformer in the mains lead with a switch to earth either end
or the centre tap of the output winding.
That would give audiophools opportunity to instantly hear the dramatic
sonic differences.

Alas, once again you failed to understand what I wrote. :-)

Another failure to understand what has already been written. :-)

This tends to be due to things like RFI filters that essentially link the
power to the case and/or signal connector 0v. I've found TVs to be a
particular pest wrt respect giving a tingle if not earthed.

However there can also be a problem with distributed interwinding
capacitance or leakage (or equivalents in a switched-mode design). Also the
external field levels will depend on the windings. (Similar to the way some
capacitors have an external field largely determined by the potential on
whichever plate is on the 'outside' of a swiss-roll construction or can.)
The Live and Neutral aren't 'balanced' and most of the voltage swing
appears on the Live end of the primary. So this can couple though at low
level to the output. With well designed and built equipment it doesn't
matter. And nor should any change in RFI injection if you swap L and N. But
in poor PSUs reversing L and N can change behaviour.

But as I wrote before "I can't comment on FULs claims wrt DACs". Nor, as
I've also explained, do I think I have to follow up every hobby horse
people ride here or elsewhere. If he wants to promote his ideas, thats his
choice. Fair enough. I'm happy to do what interests me. :-)

If FUL wants to present assessible evidence to support his claims, he is
obviously free to do so. No need for permission from any 'numbskulls'. Alas
opinions, assertions, and claims, are not in themselves, evidence - even
when written in clear English.

So I assume FUL is just having a stir and taking an opportunity to ride his
personal hobby horse. That's perhaps why he missed understanding what I've
already written. To do so would have hampered his ability to present
himself as being surrounded by 'numbskulls', etc... :-)

Slainte,

Jim

Yeabut the laminations would have to be forged by Thor and be of such an
age that they were radiation free so that ferrous would be in such short
supply that they'd never enough to make a decent sounding one;(...

I recall in the very late 80s there was a Philips CD player with a

disbelief that swapping the plug around could make should a big
difference to the sound. So much so that I knew people that marked the
edge of the cable so that they always put it back the same way.

Sorry for yet another unprovable anecdote.

The snag with these sort of things is few would even bother trying a
figure of eight plug both ways. Those that do will likely start out with a
view or hope it will make a difference. And of course the powers of
suggestion work on others too...

Do you even know what the word "polarity" means? Because the badly-written
and even more badly thought-out rant above suggests otherwise.
