Wow, I significantly reduced the noise to my audio equipments by using the Entech.
In my primary system, the noise was 110 and now it’s 31, so noise is now only 28% as much as before!
I had no idea my power outlet was so bad that I can hear a radio station and people talking!
I can now listen at a lower volume and still hear the details. Vocalist sounds more 3D. More extended in the higher notes, but not sharp.
I also measured the outlets for my network router and switches as they are part of the audio chain.
Family room stereo noise went from 90 to 20, and a 25’ long 16 gauge outdoor extension cord brought it further down to 16…only 18% noise now!
Living room went from 122 to 31 (now only 25% noise), but a 6’ 3-prongs indoor extension cord brought it to 43…only 35% noise now!

What are the Units for the numbers of the device you are plugging into the AC? PSRR Power Supply Rejection Ratio of any electronic device should be able to reject such noise from the signal. If not, the designer/topologist failed.

i do not know

[@soulshinobi]

Wait, so what is this device you're measuring noise with?

[@mrpmj00]

Monster Entech Noise Analyzer & Noise isolation Demo Entech Wideband Powerline.
I saw the youtuber OCD hi-fi guy use it in one of his videos so I got one too.

Wouldn't that be a wiring issue in the wall/socket?

[@mrpmj00]

yes
