Does an Audioquest Niagra 1200 limit amplifier dynamics?

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.

@audiotroy You answered a different question than the one I asked. I asked about how a consumer could measure the existing noise on their home line and you posted that you had tested many conditioners and have dedicated lines.

You cited me in your post and then posted something tangential -- which also helps you sell power conditioners. My question asks how one can test if they need to buy anything at all.

To put it another way, your post adds "noise" to this conversation.
