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 don’t know about the test it 50 times thing but in general if one is going to recommend a poorly understood solution of any sort, especially a pricier solution, doing diligence to verify findings can only help. Making a change and saying you hear a (positive) difference of some sort is something......but not much, especially when that is all there is for people to go on.

It’s ok to do it once and say what you hear, but not Ok to jump to the conclusion that you are infallible and others will surely hear the same thing. Even worse then is to discount others when they report something different even if based on similar low level of diligence.
Thanks, Spenav! My favorite music listening experience is the live concert. Now that it's on hold due to the pandemic, my audio system is a consolation. If I can get close to the "absolute sound" of live music, I'm willing to wait until the virus passes. What other choice does one have?  I'm truly grateful for innovations that improve on my listening pleasure. Thanks again for the encouragement. 

Please understand that all of these formulas are much easier to understand than my divorce agreement.

Nobody listens to millercarbon, why would anybody start now! Read some of his threads, he’s the only 1 that can say a tweak works and a tweak that has very little impact on SQ, MC claims it’s an “amazing” upgrade. MC needs to get at least a midfi system before a tweak can be used to see if it actually improves or degrades the sound, not all tweaks improve the SQ, some degrade it. IMO, most tweaks need a good resolving system to be able to hear an improvement. Same goes for cables, but not saying cables are tweaks at all. 
Power related items can have Big improvements in SQ. For example: the ps audio regenerators along with good power cables provide a big SQ improvement, same goes for using balanced power products. But if you go cheap and buy monster power conditioners, they actually degrade SQ.
