Does an Audioquest Niagra 1200 limit amplifier dynamics?

I used to have the Shunyata Hydra and indeed was limiting the dynamics. I tried the Niagra 3000 and noticed a difference immediately, I was able to trade the Shunyata and pay the additional cost of the Niagra.

Remove all the power conditioners, get your electrical panel and dedicated lines working instead. Those Niagara's definitely limit the potential of your system when you have clean power. 

However power conditioners served me well when I didn't have a dedicated electrical box and lines. Conditioners solve a problem that shouldn't exist to begin with.

My Bryston Bit 15 seems to do no harm...a huge Piltron transformer.

I don't know the answer to your question but I do know that the answer can vary for each individual person's system, power set up in your home, and the AC power in your area and entering your home.

Yep. Glad to see people finally asking this question.

Nothing to do witht the abiltiy of the filter to "clean up" power.  It limits rapid current changes which limits the amp.  

Anybody who has one should plug their amp directly into the wall for an immediate, enjoyable experience.
