And the energy source is?
Failing battery backed up solar or squirrel banks, the grid. AC comes into racks of DC power supplies, filtered to the max, nothing but pure DC lines coming out. A second shed for additional filtering with cryogenic filter cans and pure silver wire, with remote sensing using fiber to avoid voltage drop issues. After all, we gotta spend 40k.
That was how we converted 50Hz AC to 400Hz AC back in the 60s for Navy equipments. No big flywheel added, though.
For your application 3 phase 440Hz would ease converting to DC.
So was 400 Hz "hum" (more like "whistle" or "hoot," I suppose) a sound that was heard from time to time in audio equipment on Navy vessels?
Back in the early '80s I had a car stereo amplifier (Craig V503 I think it was) that used ~400 Hz for its internal DC-DC step-up converter. I think it had some sort of differential inputs, so there was no whistle in the audio, but I could hear the transformer itself, quietly singing under the dash sometimes.

Used to see small motor generators in the surplus store. We had a box that turned 120 AC to 3 phase 400. Fired up a gyro on it once. Cool stuff. Amazing how small and light 400 cycle power supplies are. More than one hapless customer bought a 400 cycle variac, hooked it up to to the mains and fried it. Try explaining inductive reactance to the layman...
Never heard the 400 leaking into audio on an airplane, but you can sure hear it everywhere. As a kid, my first impression was that it was the engines.
A classical guitarist from Europe came to the US for a concert. Used to 50 cycle hum, our 60 drove him nuts.

Wouldn't you need a converter to change the DC into AC for your components to change it back into DC to make music with?
Maybe he's planning to use car audio components. 😀
(Some of those can get pretty boutique-y as well, albeit not quite as nutzo as what we see around here...)

Wouldn't it just be a lot less faff to just replace the mains transformers in components with an mains led bulb and a solar cell? The main problem I can think of is apparently some mains led bulbs give off radio interference.
As far as I know ( and I stand to be corrected ) , the main inefficiency of solar cells is that sunlight is mostly of wavelengths not used by solar cells, if an led gave of the correct wavelengths it would be much more efficient. Perhaps more so than feeding a house from a center tapped transformer that consumes over 100w at idle, which has been done by an audiophile.
This is by far the most ironic comment that I have ever read on this forum! 🙄
Take care,

You have to be there to understand the basis for these guys interest in audio.
In talking to them, it was clear that they don't know much at all about the equipment that they buy and use.
The one clear thing that I picked up from them is that they strive to own "high end" anything, just because they believe it's the thing to do - because of "what they heard" from someone, not because they understand any terms related to real specifications - which they clearly do not.
It's all about "impressing" their friends - who's got the bigger amp, who's got the most expensive reel-to-reel.
Bragging rights.
Just saw on a forum. A proud photo of a faked Nordost Odin interconnect with a faked Magnum Dynalab Tuner, accompanied by the text expounding on the better sounding wire.

As a good beginning, what is good with high-end Audio and psychoanalysis is you have to pay a lot to know who you really are !.... while the therapist and his audio vendor friend go to the opera... laughing at it !
That would depend on how many you've read.
As for your ThunderWave Percussion Ribbon Controller, I'm wondering if there was a metaphor used when designing...
I beg to differ. It's a good marketing material when selling a house these days.
Not if it's only for a few seconds to get this system running. Plus, squirrels like to run.
I'm sorry but I don't understand English, thank you anyway.
Look at this and I hope that later you choose solar or wind energy to generate electricity ! 😀
