Why worry so much about the "impurities" that come in the AC network ? Why do we rectify DC in amplifier power supplies? A good well designed and regulated PS delivers practically pure DC, the residual ripple can be eliminated imperceptible figures with good filtering. (here I am missing some technical corroboration, if anyone has graphics that show that the total conversion from AC to DC is impossible, please provide the same)
It is obvious that those Vietnamese audiophiles do not understand basic electronics, Wiseoldtech could recommend a solution and earn some good dollars: 😉
How about if we look for a few lithium ion batteries for electric cars in the junkyard, (some will be operational if they were saved from the impact of the vehicle, the main reason for discarding it) Then we connect them in a combination series, parallel or both , until you find the VC of each amp rail you want to power.
We remove the connection from the PS amplifier and connect the new miracle source.
The new external PS will be good for a few auditions before recharging, we could also have a spare pack so as not to interrupt the enjoyment of the music ............ 😀

I loved it !, but surely
Evenharmonics is already thinking that he can have many arms of cheap labor in a single subject to generate electricity ! 😱 Can octopuses be bred in captivity ?

I did talk with them, and even using simple terms for things (they understand english) they reminded me of a deer staring at headlights.
They nodded, but obviously don't understand or care about specifications, asides from "big watts" and "vintage hi-end".
They're just shallow thinking gents with no real sense.
" They reminded me of a deer staring at headlights."
Good analogy, I seem to be seeing their faces in astonishment ...
Power supplies would be bypassed in all the gear, each running on one of the many DC supplies in the shed. The AC free home. Then you don't need the foil hat. 😀
I call it the Rolex effect. Sure, it's a nice, pretty watch but even if you can afford it, think what could be done with money saved if you bought a good much less expensive one? 10 year old scotch is about 40 bucks a bottle. 18 year old, same brand, might run you 160. Is it 4 times better? I'd rather have 4 bottles of the 10 year old.
People buy a Rolex for one reason. To impress others. Look how successful I am!
A guy was trying to tell my dad how great a Mercedes was. "It will last longer than your Ford." His reply, "will it last longer than 4 Fords?"
Roger Federer is not concerned because Rolex gives them to him in part payment for promoting them ........😉
I was out at a dinner one evening, and one of my friends at the table said: "That's a nice watch you have".
I thanked him, and then he asked how much it cost....
I told him the truth....... I bought it at Kmart for $11.
It is pretty accurate for those living outdoors all day long. Over a couple of weeks training, the Sun tells you as well, headings good enough as a compass on canoe trips especially at high latitudes.
And yes that is freedom.
You have reminded me of a joke that got Dave Allen into a lot of trouble for swearing on the BBC
I’ve never worn a watch in my life, I do admit being able to program alarms into your phone for days/weeks/months down the road really helps......especially with early onset sometimers! 😀
Funny, these comments about time and clocks..
Just prior to our lovely (and highly annoying) Daylight Savings Time change.
It's this Sunday at 2AM EST.
When I was a young child, I couldn't care less about the time, yet, I knew enough to be home for dinnertime, at school at the right time, etc.
I think eventually I wore a wristwatch because I thought it was neat.
And yes, as the masses do, I adhered being a slave to Time, to make a living of course.
The core of modern survival depended on such things, you know.
But I can understand the basis of true Freedom, and I practice it now, since it's been lurking all the time in the background of living.
A proper and healthy "balance" is required in life, if one is to be content, happy with things, and live a long time.
Today, I rarely wear a wristwatch, I enjoy the sense of Freedom from having to be somewhere or do something at a specific time, however there are the occasional uses that require it, being that most of society still holds fast to the concept.
Businesses, stores, travel, etc, you know....the deal.
And I have to mention that I have numerous clocks/timepieces around the house.
Mostly for decor reasons, and several timers set to kick on the lights in the evening.
But now, I'm in control of my time, instead of it controlling me.

I read that the concept started on a ship at sea. The captain needed to make a change for some reason, but no one wanted to get up earlier so he just reset the clocks.
It is purely psycosilly. "Hey, what you say we all get up an hour earlier so we can enjoy more light at the end of the day?"Cooperation would be nil, so you reset the clocks and everybody gripes, but they do it.
I remember when they tried it in the winter (the time you really need more daylight) to save energy during the "fuel crisis". It was dark when kids arrived for school, and after a few kids got hurt in accidents, they dropped it.
Towns used to have their own time. Not a problem until trains came along. Then everyone had to be synchronized so they didn't collide.
