Game Changing Tweak

I bought a pair of electrical devices called Electraclear from a company called AddPowr. They're simply plugged into an electrical outlet that's shared by your system. I paid under $300 for them and they've boosted my system's fidelity dramatically. In the 1800's,  a physicist and mathematician, Joseph Fourier, delved into the science of harmonics, and now the founder of AddPowr used these equations to increase the signal to noise ratio. (more signal=less noise) His devices act as harmonic resonators. He worked for a high-end audio cable company before focusing on this new range of products.
   I thought that when I first received the Electraclears, the difference would be subtle. To my surprise and delight, it was a stunning change. I was hearing music from the inside out. Cleaner, more dynamic, and a far greater and noticeable improvement than my power conditioner produces.
   I love finding inexpensive audio devices that work. The company makes other products, but I'd recommend a pair of Electraclears to start.

I think technical information is useful. There's altogether too much opinion, however confidently expressed, without the technical knowledge to back it up. On this site, anyhow.

IMO

So I welcome  pwerahera's contribution. It's lucid, it's exact. What more do you want, wolfie?

Why so hostile, Wolfie? We were discussing residential AC power, which varies greatly from place to place. Pwera introduced an equation which relates to that. Those who know Fourier analysis are enriched thereby - those who do not are told where to look. Again: what's the problem with that?

Oddly enough, your quotation of that equation WOULD be just as useful. If we wanted to make a fission bomb, the most important thing would be the fundamental physics that show it to be possible, and the energy-mass equivalence (up to a scaling factor) is the basis of all subsequent theory (binding energies, cross-sections, etc.).

And that assumes clean AC power. Add a lower frequency carrier wave ...

Agreed about confirmation bias. But this may be something more. Power supplies filter, yes - but as you know, it's a matter of degree, and the devil is in the details.

An LRC filter removes a percentage of the ripple present in a DC supply. The first LRC stage takes its DC from the rectifier, the second stage takes its DC from the first stage, etc. Bigger reactances increase that percentage, as do more stages - but have you ever calculated how much inductance and capacitance you need to reduce that ripple voltage to the intrinsic noise of your active devices?

Well I have, and it took most of a full size rack to contain the hundred pounds of transformers, the hundred kg of inductors, and the Farad of capacitors to provide 2 KW of good DC.

The result? My system is BLACK. Worth it? YMMV

Bemused, I think that you will find that it's a matter of degree. The equations for filters are well known, see for example a Radio Amateur's Handbook from the 50's. You will note that EVERY LRC filter filters EVERY frequency - the question is, how much.

Sure you can use a single phase motor to drive a three-phase motor backwards to get three phase, making filtering easier - but you choose your poison. I chose brute force LRC with single phase. YMMV

Mijo, do I see ghosts in my closet? Not any more.

My ’unit’ does not have a bad power supply - at least by my standards. The DIY power supply for my DIY amps has ripple which is lower than the noise floor of my test instruments, and calculates to be comparable to the intrinsic noise of a MAT12. Your standards are perhaps higher?

Bemused, have you done this experiment? What was the result?
