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.
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.
