Hi Unclejeff, the "ERS material" is made out of graphite fibers and various metallic substances that are imbedded in a cloth-like material, and is commonly sold by the Stillpoint people in 8"x10" sheets for approximately $20.00 or you can possibly purchase ERS from your local high end audio dealer.
Radio Frequency Interference practically exists everywhere from tv, radio, cellular and telephone, and microwave signals. The ERS material supposedly absorbs harmful RFI.
Fortunately, a local dealer in Hawaii had a roll of the ERS material and I bought a sheet roughly 33"x36". Needless to say, the cost was justified many times over by the favorable results that I got when I covered the top of my digital front end player and the sides and back of my amplifier. I immediately noticed more detail, speed in the lower bass, and a bigger and deeper soundstage. I actually had to lower the gain on my REL Stentor subwoofer and volume control on my amp, believe it or not.
Because of the graphite fibers, you must be careful when using this product. I was advised that the graphite fibers could cause a short in my components, so I taped all sides with electrician's tape, please be careful to follow the manufacturer's instructions.
The word is beginning to get out about this product (ERS) and you would be surprised to hear which manufacturers are using or plan to use this product in their power cord, interconnect, and speaker cables.
