Does an Audioquest Niagra 1200 limit amplifier dynamics?

For me, this question is always confounded by the fundamental question, "How noisy is my electrical line to begin with?"

The audiophile hobby is full of solutions -- some of the solutions address big, audible problems, some solve smaller problems, and some solve non-problems.

Unless I know whether I have a genuine problem, any solution proposed may do more harm than good. It's a matter of know the underlying situation.

So, to my mind, your question is more accurately rendered as,

"How can I estimate or measure the factors in my electrical setup that are either causing audible problems or impeding audible improvements -- if any?"

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

@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.
