Please tell me more about shielded power cords. Because my wall-mounted plasma TV is located too far from my PS Audio line conditioner, I must use an extension cord between the conditioner and the TVs stock power cord. Currently, I am using a heavy-duty 12-guage grounded Home Depot quality extension cord. Regarding the better video image (the topic of this post), is there a preferred/recommended extension cord that will outperform my current run-of-the-mill cords? Also, what about the stock power cord provided with the TV?
Thanks,
Ben
