What’s your vote for the most ridiculous, overpriced, and useless tweak?

+1 benjie's post, comparing the water filter / power cord. It is the last 6 feet that matters most. And not just what gets into the cable in those last 6 feet, but what gets out of it (or doesn't get out) is even more important.

If you believe the power cord is filtering RF you’re mistaken. 

Lets bad rap everything and each other its great fun!!!

>>>If you believe the power cord is filtering RF you’re mistaken.

No, I’m not suggesting power cords filter RF. I’m suggesting that well designed power cables and their terminations can prevent EMF from influencing components and other cables in the vicinity. Benji’s comparison of a water filter and a power cord should not be taken literally. For one thing, electrons don’t flow.
