I installed a Tiffany TPC 60 power cable on my Pioneer 50" rear projection TV, and got a nice improvement. The picture was cleaner, lower noise, a little sharper, and the color had slightly better saturation. I could not detect any change at all in the quality of the audio. However, the performance gain that a great used power cord like this provided, was a small investment ($30.00 ), so I definitely think it was worth the money. The only downside was installing it. I had to remove the interlock panel on the back of the TV to get to the circuit board where the old power cable connected. Then I had to cut a larger diameter hole for the new cable to pass through, and strain relief it. I soldered the new cable directly, rather than trying to install an IECC male. One word of caution, my television was old and out of warranty, so I was not concerned with going into the circuit and doing these mods. Those of you with newer sets should be aware that such cutting and soldering would likely void your factory warranty. One other mod that was fairly straight forward while I was already in there, I added a high quality OFC copper RCA connecter ( and better wire to the board ) for my composite video input. This connection is where my DVD player jacks in for video. Comparing the new connector to the original cheap pressed metal one that was original equipment was no contest . The two mods together were absolutely worth the effort.
