Mceljo, Yeah, refreshing isn't it? What I appreciate about them is absence of hype, availability of technical white papers to back up their findings, and they let their customers do the rest with glowing testimonials from all over the world.
Snopro, I totally believe you, it just wasn't my experience in my system. Two things come to mind: First, it's possible that results are system dependent, especially with differences in amps. Second possibility is that in the years since your test, Purepower has improved the 1050 significantly.
Either way, I'm willing to forge ahead I ordered another high-end power cord to test, and the first place I'll plug it into is between the wall and the 1050 and repeat the many tests I did, again (luckily I enjoy this madness). I'll report back with an update.
