Easy free tweak -- dealing with RFI/EMI -- try it and see?

With some Ciamara credit available I thought I'd try the Stillpoints ERS paper on the insides of my fuse box and Torus wall transformer to see if it helped improve things in my system. Treating fuse cabinets is a fairly well known application of this product which is designed to absorb stray RF and other electronic nasties

Well here I was tweaking away and I thought, golly the system sounds really clean and open and I haven't put the paper in yet -- I assume it will be even better with it!

Imagine my surprise to discover I'd been listening to the system with the fuse box/panelboard cover open! Turns out one of the best things to do with EMI and RFI may not be to enclose it in a metal box in the first place 🤓

And actually with it closed, with or without the ERS paper it sounded much more closed in, with a loss of low level detail

Same went for the door on my Torus transformer -- from now on I'll leave it open for serious listening -- there is a bit more audible transformer hum but as it's in another room this is no big deal

Anyway this is a dead easy free tweak so give it a try -- you may like the results
