If we go beyond these two asks, things get more complicated. There are a multitude of products on the market that purport to filter noise from AC power, and I don’t profess to know whether the Niagara 5000 is the best on the market, because I haven’t tested them all. But I will tell you that it made a marked improvement in my system’s imaging and in the realism of how it presented music. In my experience, it’s rare for an ancillary component to deliver this level of change, especially in such an unexpected way. Highly recommended.
