For a 10 plug-in comparison, go to "Live plug-in filter test" at YouTube. Doesn't include Electraclear, Puron or Stein, but many others available in the U.S. Disturbing result with Clear Line (no. 7 in the test and measurements at the end).
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.
