My experience with a TriField device is at the wall I may measure 395 and on the output side of my Puritan 156, I measure approx 95. So it indicates a 4x reduction in "noise".
Any one measured the EMI/RFI attenuation performance of audiophile power conditioners?
Hello,
I was looking for a very good/robust power conditioner which will clean up reliably very noisy/dirty power supply that I have in my aprtment. While looking for one I went through catlogs of AudioQuest, Shunyata Research, Synergestic Research etc. but no one published charts showing attenuation performance over frequency range like you get for EMI filters from Schurter or Schaffner etc. which are in the industry for EMI/EMC compliance.
Since audio is very subjective, but contrary to audio reproduction Power and EMI/RFI reduction is completely objective and can be clearly demonstrated via attenuation charts.
Hence I am asking if anyone has measured the actual performance of these audiophile power conditioners. I am not denying someone saying they hear improvement after using XYZ product, but since I am talking about power conditioning or EMI reduction it's as objective as it can be.
I am not at all surprised to see all the manufacturers not publishing the performance data, else it would be used in other industries and research fields where it's far more critical and have far more stringent requirements on the performance of conditioner/EMI filters. But I am shocked to see even products ranging above 5-10K are following the same practice of not publishing the results.
Please note I am not a measurement fanatic, but I know where I can chase the measurements and where I can rely on my hearing to gauge the difference.
Regards,

@tvad though I have tech background, I don't want to purchase something for just couple of measurements, it will be waste money.
Looks like the trifield device is being used by many though I cannot exactly makeout how it's measuring and what to make out of it except some number increasing/decreasing

Danish Audio group totally unique technologies in the $4-6k range 3 well versed brands including Borrensen, AAvic ,And the cable , line conditioner can’t recall the name begins with A , heard it vs the main stream brands and uses a bunch of active Tesla coils and other technologies to really lower the noise floor . I am looking to buy one , the AAvic I280 integrated and line conditioner same group, is my go to hopefully later in the year , being married ,things don’t always flow as easy ,especially when you have a home and upkeep !! |
Perhaps, if your power is very dirty, then you might be best to not use it. There is a current discussion on LiFePO4 batteries and pure sine wave inverters limping along on the Audiogon Forum. Be warned, there is little forum interest in this topic and few with any experience. I’m currently putting a system together based upon the rave review of my main go to guy on all two channel considerations. Regarding conditioners, I use and can high recommend the Shunyata Everest 8000. That said, getting off the grid has real appeal. |
