By the way I improve it with some shungite and herkimer diamond and with an improved power supply with tourmaline...I must say that the improvement is not small nor doubtful, I am surprized....I ask for myself now this question: why paying many hundred of bucks for one? Acoustic revive sell some at too high price for me. I realize I have replicated many of their priceful products or ideasor replace it tough at no cost or very low... Nevermind! The shumann resonator is not useless, overpriced, ridiculous tweak, if you buy a china made cheap one...
But before buying one, beware! You must treat your room, clean the electrical grid, and eliminate or control vibrations,after that and only after a schumann resonator will make a great audible impact...
