How can you tell you’re a victim of polluted AC power? Listen and look for these symptoms: Flat, hard, and grainy high frequencies, a thick and bloated midrange, fat, uncontrolled bass, and loss of air and soundstage stability. On video displays the picture resolution is less than sharp, with “ghosting”, color shift, “snow”, or vertical and horizontal lines. If this looks and sounds familiar, you need Furutech!
