Measuring line noise and power conditioners


I recently purchased a Trifield EMI (Dirty Electricity) Line Meter to measure noise coming from my outlets. To my surprise, my $500 power conditioner (name withheld to protect the potentially innocent) appears to not filter any noise per the Trifield readings. In fact, with some of my outlets the measures are higher through the conditioner’s outlets, than the measures coming straight out of the wall. The manufacturer denies anything is wrong with their conditioner, claiming the Trifield is measuring the wrong frequencies. Can anyone explain?

@steakster ,
Those are some pretty nice quotes. Jimi was more than a musician. I especially liked the one the went,
"I've been imitated so well I've heard people copy my mistakes."
Seems he also had a great sense of humor.

Wow. Just, wow. Seems like every discussion on audio brings out the worst in people: those who decry things due to, measurements, and those who actually use their ears and report their findings.

Then comes the acrimony, the insults, the authoritarian know it alls who talk down to the less well versed, but better listening crowd.

It's why I've taken to posting a whole lot less as this place has been taken over by the same breed as the YouTube crowd. Anyone notice how many audio review sites no longer have a comments section or have simply stopped online publishing? 

Too many ids unleashed thanks to the internet. If those thoughts and words could be manifested, we'd destroy ourselves overnight, like the Krell did in Forbidden Planet.

All the best,

Before I got my Audioquest Niagara 1200, I read where a lot of manufacturers of conditioners go for a change in sound, rather than good filtering of AC hash on the line.

But to go so far as to discredit all makes of power conditioners is silly. I haven't personally measured the noise on my lines since installing the Niagara 1200 but I've seen demos online showing the differences with noise sniffers and meters and it works as advertised. 

In fact, it's probably the single biggest gain with a "tweak" I've experienced. I hadn't realized how much filth there was on my incoming AC.

All the best,
