please tell where one can get this sniffer . Would be great for many to show sniffer results with different brands of power conditioners . also what is the noise harvester and how much do they cost . Thanks
AC mains noise Borrowed noise sniffer and tested my AC lines...
I borrowed this AC line noise sniffing device (Blue Horizon Mains Noise Analyser) today. (Do not ask from where, I do not feel at ease saying.)
This device sniffs out noise and has a range of "000" to "999" and over that it just is "MAX".
So first test was kitchen light with wall plug. "784"
Kitchen outlet tied to refrigerator (frig ON) "MAX"
Bedroom wall nothing around in use "220" wow good number.
Furutech Duplex at amplifier "013*" WHAT!!!! yes "013". That is on a direct 44 ft extension cord from 20 amp wall outlet (also Furutech) * with the C7 to the noise sniffer one way, it is 13, other way it is 20. ALL the measurements change with reversing the noise sniffer AC plug, about the same amount each time)
That extension does have an additional Furutech duplex on the cord, six feet back of amp Furutech plugs end, and that duplex has two PS Audio Noise Harvesters. The wiring is a quad twist. and each side or pair is connected to one out side. so each Noise Harvester is on one half of the quad.
So I can say the PS Audio Noise Harvesters really DO a fantastic job!!!
The other similar line (from he same 20 amp outlet) does not have any Noise Harvesters on it. And with the stereo running, it has "297" noise level. However IF I do stick one PS Audio Noise harvester in an out 3 feet back ot the one the sniffer is in. The noise drops to "143". (I cannot leave the Noise Harvester or a pair in there due to it being in use, normally, plus adding them in where the noise sniffer is, seems to make the sound go too thin.)
Another major discovery is just HOW NOISY Digital equipment really is!!! I have my two CD changers plugged into a separate power conditioner. A PS Audio P-600.
Testing the PS Audio P-600 I own (tested at 60Hz) With nothing turned on plugged into the P-600 the baseline noise is "040" With one five disc CD changer turned on the noise level jumps up to "740" With the other one only on the nose is also "740" with both on the noise jumps over "MAX" This is with a PS Audio Noise Harvester plugged into the same duplex (on the back of the P-600) as the CD changer!
On the other hand.. The Marantz SA-10 is pugged into the Furman (also with a PS Audio Noise Harvester in same duplex and that area is "032". So SOME equipment is not spewing, and some is.
This is all I have learned in a half hour of fooling around.

The device,
Blue Horizon Mains Noise Analyser, is available in EU for Euro 657.02 to destinations outside EU and Euro 795 with EU tax. https://www.kempelektroniksshop.nl/blue-horizon-mains-noise-analyzer.html I would think it is also available else where. That is the first Google to 'buy' I own a Furman REF20 several years old when I bought it used nine years ago on the goN' for $1,300? $1400.. close to that.. and I recently replaced all the OEM duplex in it and put in Furutech GTX. (But put the individual little piggyback filters from the OEM duplex, onto the Furutech same way as OEM.) Some GTX-D Gold, Some NCF Rhodium ((The PS Audio P-600 also has all Furutech duplex now)Noise at the extension cord duplex (where the actual cord to Furman starts) is measured at "297" The ONLY outlet I measured in the Furman, a 'source' 60v/60v balanced duplex measured at "032" the first time. No music playing. But system on. Second measurement twenty minutes later was "003" (I am thunderstruck.) Music was playing. PS Audio Noise Harvester: https://www.musicdirect.com/power/ps-audio-noise-harvester-blackI bought them on a sale where if you bought two or more, they all would be $50 each. That sale is over. I bought seven. i am using five. My spare two are not for sale! The are a little box with 2 prongs for AC.. and they suck up the noise, and when the capacitor inside gets full of the noise energy, it blinks the diode sticking out the top. There are many variations from different companies. All the others more expensive. Even the Noise Harvester used to be $199. Then $99 Now it's at $75 a pop |
