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.

$300 is a relatively small price to pay to make a discernible, appreciable improvement in your audio system. Those of you who dismiss AddPowr products
out of hand are nervous about spending that sum because either you don't have the money or you're prone to an automatic self-righteous reaction toward anyone who claims to have invented something new. It smacks of the Inquisition. How can you make such pronouncements without first testing the product in question? I'm sure your money would be refunded by the company if you're disappointed with the results.  If you have ever visited an audio show, you can come in contact with electrical engineers who were involved in military projects like the development of the AWACS system or have worked for NASA.  Advancements in technology are ongoing, especially in electronics. To deny that is tantamount to burying your head in the sand. If you think interconnects from BestBuy are as good as any other, then these products are not for you.

Like everything else, only the ones who have tried it should have a say on whether it works or not. You can always try it and return it if it doesn't work for you.  No need to play the scientist or the prophet. Don't let the marketing scare you.  Most of the time the marketing group is totally independent of the engineering group and they don't necessarily see eye to eye.  I know many designers/engineers (Gallo, Carver to name two) who have walked away because they couldn't stand the marketing tactics of the company they work with. At the end of the day, things either work for you or they don't.  You just need the courage to admit it to yourself.

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.).

A critical element in making a statement regarding a product, the source of which the manufacture makes a living from, necessitates owning and having a real experience with.  I own several of products by this manufacture and can attest to the significant improvement they have made.  The owner, developer, and designer is generous with his time and genuinely takes interest in how one experiences his products.

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
