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.

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?
prag,

It’s the only argument one has when there is nothing concrete to substantiate a claim. Why people choose to spend money on things that apparently work by magic rather than for some good reason is beyond me. It’s a personal matter mostly. People spend money on all kinds of things, some crazy, some not.

My theory is obsessive personalities cannot stop themselves from pursuing their obsession.  Figuring out what can be done to make things sound better is not easy.  But at some point it becomes grasping at straws if not reeled in. 
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
There is no "bad" anything.
In fact, 

The ADD-Powr idea is not about filtering noise.
It adds signal, and does not filter  nor address noise.
Do you remember the term signal-to-noise ratio, or S/N?
If you increase S what happens to the ratio?
My math says the ratio gets larger.

Go get yourself a dB sound level meter.
Play pink noise or white noise into your system.
Send it as mono or stereo feed.
Take said meter locate and position and point it at:
1 - 2 feet from each speaker
Repeat from 5 feet.
Repeat from the sweet spot between speakers 
Record the measurements.

Plug in an ElectraClear or any ADD-Powr product, and repeat the above.
End of story.
