Hi firstcut. I recently switched from a Audioquest Niagra 7000 with an Audioquest Hurricane 15 amp cable to the Synergistic SX Powercell 12 with the matching Gallileo SX Powercord. The Synergistic kit is hugely better - wider, deeper sound stage, more holographic sound with much greater detail retrevial. You hear much deeper into the music as noise is reduced making music more realistic. The Niagra was good the Synergistic is outstanding. One thing to bear inmind is the the Synergistic does not have surge protection - I got round that with a Puritan Guardian plug.
I have not heard the Ansuz conditioner but do rate their isolation products. Hope this helps.
