Does an Audioquest Niagra 1200 limit amplifier dynamics?

The 1200 is OK, but as above, the Puritan PSM156 is much better, its certainly better than the Niagara 3000

I just bought the Niagara 1200 , My art audio concierto amp is connected on the high current section, Dynamics and noise floor improve. In my system I don’t sense the power is  affected at all.

@j-wall Very helpful. I could get the PS Audio on trial, but it would be nice to measure first before laying down thousands. 

I just completed a test with my Niagara 1200. I did not detect a difference in the quality of music when I connected my Luxman 590 AX II Integrated into the Niagara 1200 High Current outlets vs the other outlets on the Niagara 1200, vs my dedicated 20 amp wall outlet. I have not owned or auditioned it but I agree with markiew ((above), the Puritan Audio PSM 156 could be the answer to several issues that others are having.

I have the Puritan 156 and the Isotek Sigmas EVO3, and while the Isotek is good, the Puritan is better (and less expensive).
