Stillpoints ERS cloth for EMI/RFI

If you have experience or knowledge- in how many areas of a cd one box player could this material be effective on, and how to install?. I have read about transformer noise, digital chip processing noise, clock noise, etc. Would like to try full blown use for inside the box noise as my line isolation & conditioning are well handled.
I suspect one might be better off wrapping the transformer with mu metal, you know, something that absorbs the magnetic field the transformer produces.
I wrapped the transformer in my Furman balanced power conditioner because I noticed that this is what BPT does to the transformer in their units.

It made an improvement in my Furman, so I bought more sheets and wrapped every transformer I could throughout my system.

I don't know if it is shielding incoming EMI/RFI or outgoing from the gear.

All I know is that I like the results.

If I ever come across mu-metal and it's as cheap as the ERS, I'll certainly give that a try.

Something tells me that cutting and fitting cloth is easier than cutting and fitting metal.

I use electrical tape to affix the cloth.

What would you use to attach mu metal to a transformer?
Thanks Lacee. Sounds worthwhile although I hope to get more feedback. I haven't figured out how to use mu-metal as my research indicates an annealing-in a hydrogen atmosphere I think- after it is formed. Hopefully someone knowledgeable will "chime" in :-)
Mu metal is not expensive, I'm guessing the same price per square foot as the Stillpoints stuff and can be wrapped around the transformer since it comes in thin malleable sheets that can be easily cut and also placed below and over the transformer. The issue of course is the powerful and toxic magnetic field produced by the transformer as a consequence of you know the current traveling through the wire, not to be confused with an electromagnetic field, that affects everything within proximity. One layer of mu metal absorbs about 75 % of the magnetic field, while two layers absorb about 96% of the magnetic field, which you recall from high school is orthogonal to the direction of the current flow.
