ECO 3 is a superb new product from Nordost that treats a problem long ignored in the hi-fi industry; the build up of static charges on the surface of the loudspeaker, signal and power cables. These surface charges can interfere with the signal and introduce background noise into a hi-fi or home theater system. After treating your cables with ECO 3 you will notice music sounds more defined with any harshness removed. ECO 3 is a proprietary formula developed by Nordost but will work with any brand of cable.
"And get this: every time you spray another piece of gear, the sound jumps to great liveliness, life, and 'thereness', as in immediacy and presence. …Tell them HP sent you." Harry Pearson, The Absolute Sound No. 109
