I hate to be a negative nancy but we tested the Niagra 7000 and were not that impressed vs our reigning champ the Audio Magic Oracle.
In our $150k Reference system the Niagra made the entire system sound noticablely more closed in and less musical then the Audio Magic.
We were going to purchae the Niagra but sent it back.
We have also tested noise meters on many power line conditioners just because the line noise is low doesn't mean the power line conditioner is producing a sound quality improvement that is different than just noise reduction. In our tests of many power conditioners it is the improvement in soundstage width, depth, and macro dynamics that are greatly improved vs just lowering the noise floor.
For the record we have tested Running Springs, Isotek, Silver Circle, Audience, older Shunyatta older Synergistic Units and a few others.
With any power conditioner you must test it yourself.
