Two of the worst villains in the land of HiFi are RFI (Radio Frequency Interference) and EMI (Electro-Magnetic Interference). Stillpoints ERS Cloth is one of those “budget tweaks” that will make you shake your head in disbelief! The core of the ERS cloth is a blend of carbon fibers coated with proprietary metals that make it virtually impenetrable to RFI!  Although it's no thicker than construction paper, the ERS cloth will lower the noise floor on any piece of digital gear, amp or preamp, loudspeakers and especially power conditioners and power cables. Uses for the ERS Cloth are limitless! If every audiophile out there experimented with just a single sheet of this magic cloth, we would have a lot more very happy customers! Available in 8” x 11” sheets, but may be cut using ordinary scissors to any size or shape.  Also available with adhesive backing.
