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.

@tvad I live in India. @cleeds From your comments I can completely understand that you have no idea whatso ever about Indian HiFi scenario. And since you have no clue about the scene hence your ignorant remarks.

My system is rocking and I don’t even feel for a second thst there is any component that I don’t like in my chain or I should have tried to listen to some component before buying.

Besides coming to the original point, for power conditioner there is no part of it’s performance which is subjective. Every aspect of power conditner objective and it can be measured.

Thank you. That helps narrow or eliminate auditioning recommendations.

Your other comments are quite helpful to put your listening paradigm into perspective.

Have you participated in AudioScienceReview forums? I think you may find a welcoming environment with members who share your point of view. Perhaps you can find useful help there.

@tvad I don't post there, neither I take Aamir's reviews very seriously as I don't find much value in his methodology. It's a bit like gun in the hand of a monkey (take this as an idiom and not the literal comparison) & now he has a following. I am very much aware of subjectivity in this hobby but at the same time I very well know where I can be objective.

It appears you make quick assumptions about people as you do about audio components. I wish you the best of luck in your efforts.

I don’t see any Furman power conditioners on your list audio_phool.  That’s a well known name for power conditioners.  In fact, I had a Furman PF15 elite on my stereo system for several years.  I tried it with my big Pass Labs X350 amp that I had back then but it didn’t work well with the power conditioner.  So I leave my amps plugged directly into the wall.  

I brought home the AQ Niagara 5000 with a Hurricane power cord to audition with my current stereo two years ago.  It was quite a step up in sound for me.  Despite being very expensive I kept it.  So I moved the Furman power conditioner to my Home Theater system.  I was using just a MP Surge protector on the Home Theater system.  The Furman power conditioner amazed me by how much it improved the television picture.  The colors are brighter and richer and the images much sharper.  My experience with these two power conditioners has been quite positive.

If you can find a way to correlate sound quality to specifications- especially EMI reduction specs, more power to you.
