I’m not a fan of most power conditioners as I dont think you can actually condition your a/c so cheaply
This is a big reason why I use synergistic research "power conditioner" Most of the sound benefits here come from the power cord, outlets, grounding, ext. The folded EM cells are supposed to provide AC filtration. I’m not sure if thats actually true but unlike the overwhelming majority of conditioners in the market, it doesnt restrict dynamics. In fact, I’m thrilled to plug in my power amp to the SR unit as it actually increases available power reserves.
I tried the AQ and Shunyata equivalents. I even tried the powerplant. The unit that gave largest sonic improvement with least restriction was the synergistic unit. I’m actually scared to switch over to something like the AQ
