Hey Z, thanks for getting back to that question I raised. That last 6 feet is a mysterious 6 feet. I am, certainly, not questioning the difference it appears to make, especially with stock power cords. Just the fact that everything you mentioned, as legitimate as it is, can be done, it seems to me, for a couple of hundred dollars. Not $1200, or $600. I have no experience with those big boys and they might, just, make a difference, but like I said, I can't go there. I, still, think that the electric that comes right out of our outlets, traveling that long dirty, evil electric highway needs to be filtered, tweaked, purified, whatever, which I don't think any power cord, regardless of price, can do. BTW, just to get off the topic for a minute: it's snowing here VERY big time. We're talking blizzard conditions, in Point Lookout. Got the whole day to ramble on in between shoveling. Hope some of you will be home today. peace, warren
