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.

Once again, those who clamor most often for blind listening tests reveal they don’t have a clue about valid testing:

mijostyn
You have to be blindfolded and sitting in your listening position. Have a friend or your wife plug and unplug the unit. All he or she can say is "OK" when they make a change. You say "on" or "off" after every "OK" That person keeps a record of your responses by writing down R for right and W for wrong. Record 50 responses then determine the percentage of right and wrong answers.
Any listener would naturally score 50 out of 50 on that test, or 100 out of 100 if they could stay awake long enough. That’s because the person conducting the test is telling the listener that they’re making a change to one of just two options, so if it’s changed from one it must be the other. That’s pretty silly.

Valid blind testing requires a lot more than a blindfold. Once you understand how cumbersome and tedious and time consuming the process is, you’ll understand why such testing has so little value to the typical audiophile. Or perhaps you’ve already learned that and so have just not bothered to yourself conduct your own tests.

If I’m mistaken, please share the results of your tests. I’m genuinely interested.

@ladickinson -  You say "low frequency AC harmonic".  The signal in question is not related to the AC 50/60 Hz sine. I repeat - It is not an AC harmonic. There is no injection of an AC sine harmonic. Do you get it?

Rather, I suggest a low frequency signal, presumably a square wave, that is the result of signal processing circuit design, that is impressed upon the line. It is the square wave that is composed of a harmonic series of sine waves. 
Not "absurd" imo.

I stand by my statement of power supply filtering in audio gear.
I didn't say that a power supply cannot filter low frequencies. 
It appears you are locked into a fixed position of intellectual judgment and therefore dismiss any idea that disagrees with your intellect.

On an another note, it is up to the manufacturer /designer to reveal the complete recipe of its unique "sauce."

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.
