Aluminum Box: The box I used to put my 500VA MGE 91095-32T Ultra Linear Isolation Power Supply in is called 'DYT-1 Heightening Full Aluminum Enclosure':
https://www.ebay.com/itm/302660809662?ViewItem=&item=302660809662. Please note if you get this box, the switch it comes with sounds horrible. I recommend this one:
Canal R Series Rocker Switch Double Pole 16A, which sounds much better. Its not a drop in fit, so requires a little filing, but the result is well worth it.
EMF Meter: The meter I used is the TriField EMF Meter Model TF2:
https://www.amazon.com/TriField-EMF-Meter-Model-TF2/dp/B078T2R64C You can see the seperate measurements listed for magnetic and electric fields. In my experience, they are related as you state alpovs, but from my basic experiement it seems the magnetic and electric fields can be
managed seperately. More on that below.
I experience heightened tinnitus when having headphones on, plugged or unplugged. The Topaz (MGE) seems to not impact my wearing headphones. If anything, it makes them for tenable. On the other hand, boxing the Topaz (MGE) and putting Faraday Fabric, has increased my ease around my audio system greatly, so that is my focus here now.....ie. focusing on that which I can control
Faraday Fabric: I used 'Mission Darkness TitanRF Faraday Fabric':

Note that the faraday fabric did almost nothing to stop the magnetic fields coming from transformer. So sitting a distance away (about six feet) is the solution for me. However, the faraday fabric and aluminum case did a great job blocking the electric field, and this seems to be what impacts me the most. The benefit was not subtle, it was obvious. My whole body relaxed and the tinnitus in my ears lessened. My wife kept walking in and out while I was experimenting and she also commented how much better it felt when the Transformer was in the box with the faraday fabric. I'm convinced these fields impact the human body now. My wife and I both feel the big power lines, now I know the effects exist inside my house too. I have found a couple other 'culprits' in the house too. I sold my ultrasonic humidifier and got a 'cool mist' humidifier, and I unplug my microwave when not in use. I'm sure this must sound hokey to many, but I honestly feel better, so I'm not going to argue with that, ha ha
Kudos to JS-2: I want to give Kudos to Superdad here too, I just got an uptone audio JS-2 DC linear power supply which is incredibly good. It just smoked another expensive linear power supply I was using. So I know others here understand way more about this stuff than I do. I am a musical instrument designer by profession, so I am very good critical listener, and do believe our bodies (ears are part of our bodies) are amazing at reading information our minds may not yet understand. So I am just trusting my direct experience when I share.
