Got 10 today and spot treated areas where I felt contributed to the most noise. Fridge circuit, AC circuit, computer room, put one on the hepa air cleaner in the music room, and another on a fan in living room my wife uses.You can purchase on Amazon. Just search for "mix 31 ferrite" and verify that the one you choose is mix 31. This ferrite blend suppresses a wider range of frequencies than typical ferrite mixes. The one I posted has 1/2" diameter but the come in a variety of sizes.
How did you end up with 4 filters per circuit? Trial and error? Any problems with more?31mix beads on all lines except the 2 dedicated 20A lines for the system. Don't shoot it until you try it!
I'm no expert so someone please feel free to speak up if I'm out of line.has any of these mods been tested by non listening methods ?
less noise can be rolled off highs
has any testing been done before the psu and after
no mods and mods
I’ve done this and very little is made on the audio path with no mods. we get obsessed on mods but most including myself listen alone. The one place I can confirm any shielding matters is in a computer based process used for audio. We can’t really fix EMI aside of re direct it’s radiating pattern. RFI yea but does it matter everywhere
any ferrite used are tuned to freq it loads to lower
But this also affects current flow of high demands are needed.
A question do the beads at the panel feeders get hot ?

You have a great sense of humor.I build with EMP harden devices on a piece of plywood as I wear my Grand Enlighten One of the Bavarian Illuminati of the United States official tin foil hat. It goes with the ring I can't wear while working on electronics.

I recently bought some genuine shungite pyramids. The idea is they neutralize EMI and RFI. Apparently, high purity-stones of this variety can also purify water. I don't think the shungite will influence how my audio equipment sounds; since they are far from sources of contamination, such as a Wi-Fi router/unused inputs covered. Let's see if helps with my low energy levels. For the past few weeks I've been very tired (yawning during the day) and if it does make a difference, then we know EMI and RFI are the culprits. I still sleep 7-8 hours a day and eat healthy food/don't drink anymore.
