out of curiosity did each outlet read the same in terms of noise? was one end noisier than the other?
Audioquest Niagara 7000 tested with Power Line Meter
A few months ago I bought a Niagara 7000. Upon plugging all of my components in I noticed an immediate, dramatic improvement in the sound. I was blown away.
This post is not a review of said unit, but I wanted to share with you a test I did in comparing the noise of the electricity in my house to that which is coming from the Niagara 7000.
I bought a Power Line Meter from Alpha Labs. https://www.alphalabinc.com/product/plm/
My local dealer had one at the shop and I immediately wanted one so I ordered it online.
I plugged it into the outlet that the Niagara is plugged into and it read between 1100 and 1200 mV. For comparison, I tested the power at my office and it read in the range of 450 mV. Needless to say, my home power lines have a lot of noise in them!
Now, when I plugged the meter into an outlet on the back of the Niagara it read only 11 mV. That is an incredible reduction in line noise. I did not expect it to read so low.
The dealer I mentioned did the same comparison between the standard outlets in the shop and a Niagara 5000. Without the Niagara it was around 500 mV and with it was around 50 mV. I had wondered what the performance gains might be between the 7000 and the 5000, considering the former costs twice as much. If the meter test is any indication, the 5000 allows around 5 times the noise through.
Granted, none of these tests are done scientifically or in a controlled environment, but they are still interesting numbers.
It would be interesting to test different brands of power conditioners to see how they compare.

In the June, 2017 issue of Stereophile, there was a head to head comparison of these two units. I couldn't find it online so I guess it hasn't been posted yet. As I recall, they gave a slight edge to the Niagara 7000, but it was very close. The Niagara is $3K more than the Denali, so who is to say if that is money well spent or not? I would like to do a comparison myself someday if I get the chance. It is my belief that both products are of the very finest quality. |
Hi Snackeyp, In case you are interested in my choice of Audioquest Niagara 7000 over Shunyata Denali 6000 S. The 7000 was 1.8x more expensive than the 6000, and I still preferred the Niagara. Here is my link: https://forum.audiogon.com/discussions/shunyata-or-synergistic-for-power-conditioning |
