Discovering I may have the cleanest AC power in USA

PS Audio Noise Harvesters are on sale. $50 each.. So naturally I had to buy a pair. 36 hours later in my home.Well I clean the prongs, Caig Gold them, and plug them in.
Nothing.
Nothing.
I am wondering broken? DOA?
I move them to other outlets not on my stereo in the kitchen, in the bathroom (the bathroom has a air cleaner plugged in the same outlet, motor running). OK a single blink.
I remember the dimmer thing. Plug the Noise Harvesters into the stereo again.. and turn on the only dimmer in the place (in the bedroom, on a different circuit) KABLAM!!! Now they are blinking pretty regular. OK they are NOT broken.They also blink when I put them on an Adcom AC box also on different circuit than stereo. Both the Cable internet box and the WiFi box are on it. And yes they blink every minute or so.I checked the Furman REF 20 outlets, no blink. The direct to the amp.. no blink.+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
So I apparently have just naturally the cleanest AC line in America? (For my stereo equipment.)
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Part of it may be the fact I packed the duplex enclosure 20 amp single line I use for the stereo with small quartz crystals coated with Automotive dielectric grease, in small baggies, the duplex is also the Furutech GTX NCF type, and the wall plugs are also filled with the loose small quartz crystals, plus some flattened baggies of the crystals wrapped around the outside shell of the plugs at the wall
Good thing I only ordered two of the Noise Harvesters. More are not needed. (and I actually do not even need the two. but that is OK. I can keep them as a sentinel, to know if I ever get noise on the lines.
So I do not know if my home made anti noise crystals work magic? (along with the Furutech NCF which is basically a refined version of my own crystals) or if I really do have some of the cleanest AC around. (PS I live in a 90 unit apartment building, folks above below, around me. Things like my frig I have several ferrite cores with the AC zipcord wire wrapped in and around them, ditto air cleaners, lamps..

The notion that one device, however expensive ( $2200.00 highly engineered Akiko Audio Corelli passive power conditioner) sets the bar for all others is an incorrect assumption.
I have noticed that my Furman does stop the HF in the toroid transformer. So outside noise does not get in, and inside noise does not get out. Nor does the HF noise added to outlets in the High current get to the low, nor the reverse. The same is true for the normal transformer in the P-600 I own.
The added notion that "" Any experimentation without a calibrated meter is merely guessing, wishful thinking and a waste of time ""Is perhaps closer to being partially true. However it certainly is NOT wholly true. The calibrated meter may AFFIRM what one has found without such a meter, but the experiments with the Noise Harvesters certainly do help one to know what is polluting, and when the blinking stops, that at least that part of the grunge has been located and separated from the system. But since the Noise Harvester is not a full range device (It is for 10,000Hz and above) a meter might be useful. Though not a ’requirement’ as kodak805 wishes to claim.

Forget any speculation as to what a Noise Harvester can and cannot do or what a more expensive device might do better.  Again, without a properly calibrated power line meter there is no objective way to know.

A blinking led will not tell you very much, especially given the tolerances in a cheaply made device.  For the price of less than three Noise Harvesters the doubt is easily resolved.

With the maxim of all audiophiles: "Where you can spend a little, way better to spend a LOT" I suggest skipping the cheap $150 ’distortion’ gizmo, (which only selects a particular harmonic btw) And splurge twice that or three times that and buy a real oscilloscope from Amazon. Then you get the Whole Enchilada .. And you can analyze your power until the cows come home.         
ADDED: and for less money than $150... you can buy a USB oscilloscope for $80 or so.

Well Elizabeth, I cannot disagree with your purchase suggestions. So, unless you are reluctant to find out what may be revealed by any measurement device, why not buy one and let us know what you find?

Couple of things:
Furman devices with SMP naturally filter starting at about 3 kHz. This is because the surge protector is effectively a low pass filter. This behavior is what makes series mode surge suppressors superior. It is nearly impossible for a high slew rate surge to slip through. Unlike all parallel mode / disposable units. This also means they don't current limit in the 60 Hz range. An ideal situation for amps.

Further, LiFT adds some active noise cancelling which to my ears clearly works.

I also like to keep an eye on the voltage, it is how I discovered my building was running 130V and got them to readjust the city’s load balancing. :) Seriously.

Best,
E
