Stillpoints ERS cloth for EMI/RFI

I can't say that I've gone as far as trying ERS cloth inside components. I got as far as trying it around cables and on top of various components in large, medium and small sizes of the material. I experimented with ERS cloth in two highly resolving system over the course of two days. The results were consistent - while the ERS cloth affected the sound, even in small amounts, the sound lost its sparkle and sounded rather compressed and wooly. I found out that even having a sheet of ERS material sitting on the coffee table hurt the sound.

Geoff i wish I had ears as good as yours.

Steve , why not around the transformer and clock?

Hi Ptss

This is one of those products you have to experiment with, too much and you'll get the results that Geoffkait notes as I too have experienced. I've been using it for about 10 years. It DOES work in making things quieter but you don't want it to interfer with the music either, just noise from RFI/EMI. Best thing is to buy a sheet and experiment. I have it on the small transformers in my Berning amp. I also had it on over the impedance converters in the amp but discovered after removing it over a period of time some of the sparkle in the music came back without gaining noise. Results can be dramatic or subtle. You can try a small piece on the top of different components and see what happens. It's effect is going to be different depending on the system, noise your system is picking up and other things unknown, the audio voodoo gremlins. I'm not sure there is a clear answer, in any case use judiciously and DON'T line the inside of any component, I doubt you'll like the result.

I was thinking of lining the Equitech I use for the TV as I already have Bybees inside.
