"Pick up a Radio Shack Digital clock for $17.99 CAT. NO. 63-796. Plug it into the wall (at the system) and allow the capacitors inside the unit several minutes to charge the house main. Over a peroid of 20 minutes you will begin to hear increased bass performance and cleaner sounding high's. Over the next 60 minutes you will hear your soundstage bloom with increased width and depth and much better imaging. Video perception is actually very interesting. If your looking into tweaking your old RPTV into HDTV quality I can't think of any other method that out performs the digital clock. Increased color saturation, less grain, and video depth (increased blacks) are some of the few traits of this tweak." The pulsing of the digital clock put in the same AC outlet that your home theater is hooked up to increases the electrical signal for the whole system. The father of this tweak to my knowledge is George Tice. Maybe some of you have heard about the Tice Pulse Clock, well here it is. George did a demo for the media back in the late 80's descibing a new technology that enhanced electrical power. For his demo he used a simple digital clock and said his new technology was already installed inside the clock. The members of the media (with the exception of Stereophile) liked the demo. This new technology he was basically describing is now known as "parallel filtering".
