ERS cloth is best used as a dusting rag for the CD/DVD player. It is like putting a blanket on a hot surface. Heat is the #1 reason for equipment failure. It does nothing for EMI, verified by meters around the world. We once used 5-sandwiched layers of it and did not drop EMI signal by even 1db. Worst yet, is that at "best" it reflected 1db back into the source... kind of defeats the purpose of in-or-out shielded appliance. I still suggest listening to equipment without re-injecting distortion. You can read more about this under the "theory" page on Audiav's website. Please, for the sake of the audio community and it's actual role in legitimacy, do not fall prey to Music Direct's eloquent spins. The best thing to do is use anything but ERS cloth (unless dusting)... many tweaks could help you- namely anti-vibration and anti-magnetism. EMI is a concern due to the processing chips on the board, but unless your chassis is made of plastic or a top-load that has not been properly designed, the disc player may not be a culprit for EMI shielding. There ARE redeeming traits to may of the technologies out there, but you should do the testing yourself and not jargon from those that have not tested it. Go and buy an EMI/EMF meter for $150+ and see what happens before & after you apply the ERS cloth. If nothing happens, then your meter is working fine :)
