Furutech Power Guard E48

 The Power Guard-48 is a sophisticated finished inline power filtering cable that eliminates many common problems caused by contaminated electrical power lines. It protects against distortion caused by ground noise, voltage spikes and sags, high frequency power supply noise from other components in your own system, and finally high-frequency digital noise emanating from processors and digital interconnects. 

The Power Guard-48 Inline AC Filter lowers noise on every component on which it’s used resulting in very natural and extremely fine resolution down and through the utterly silent noise floor. It improves soundstaging and imaging while creating nuanced high frequencies, an attractive, engaging midrange, tight and controlled bass, with power and dynamics to spare.
