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.

That's why it pays to test components in your own system.
Criminal? Really? Good luck to you as you try to warp the law to suit your opinions. |
Many local dealers allow in home auditions. Many online dealers allow returns.
It’s not likely that an audiophile will spend $28K on anything without an audition first. You’re just being silly. |
It’s certainly true that some dealers do not offer home auditions. I’ve found that the "better" dealers - the ones who sell gear other than just mid-fi or mass market electronics - usually do provide the option. Many online dealers advertise 30-day (or longer) trials. Brick-and-mortar dealers who offer this option don’t necessarily advertise it and it’s likely they won’t offer it to some nameless voice on the end of a phone. If you’re in the shop, it’s likely they’ll qualify you before offering the option. It’s that way with many high end sales. Home auditions are common, so simply stating "that option is out of the question" is plain silly.
I can’t imagine buying components that way but I hope it worked out for you.

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