Confronted by cable manufacturer on Head-fi

I too, have spent alot of money on power cables...not for sound but for my computer monitor. I found visual nirvana entirely by accident. I was on my desk trying to plug a firewire cable into the back of the comp case while holding a butcher's knife in my right hand. I slipped while on the desk and the knife came down on the monitor's power cord in a glancing fashion. The blow stripped off part of the jacket and had embedded itself about halfway into the hot lead (missed the neutral & ground leads). I left the knife in the cord as it was stuck there but thankfully wasn't arching out on anything. The monitor still worked and indeed looked different in ways that are scientifically indescribable. Somehow the damaged power cord with the additional conductive steel blade broadened the color palette from what was "closed in" or restrictive. I couldn't leave it that way so I killed the power, pulled the knife out, then repaired the power cord. Over time, I became less satisfied with the performance of the repaired stock power cable (compared to it's freak accident state) as it seemed to be clamping down on vitality of the screen...colors seemed bright yet subdued, and gradient areas seemed to lack cohesiveness. I still had that "It only carries voltage & current" mentality in regards to power cords, so I thought that some other component must be going bad. I tried several different video cards set at 32 bit true color and they did not improve the display quality. I knew it wasn't the monitor weakening either, as it was less than a year old and still had a strong gun in it. I started to suspect the monitor's video cable as I did notice that someone had written some kanji on the cable with a Sharpie and there were dirty fingerprints (probably mine) on the thumbscrews at the "D" connector end. I sent the monitor back over to Sony in Japan and had them replace the cable. No change. What the hell I said...could it be the power cord? I needed some colorful images to display for comparison purposes so I hit the rotten.com site and pulled up some accident photos. I then pulled the electrical tape off and stuck the butcher knife back in the damaged spot and sat back down in front of the screen. A wave of natural endorphins washed over my brain as the images now sprung to life with the hacked cord. The vast improvement in quality left me emotionally drained for days. I ignored the danger of the sharp, electrically hot blade and left it there...then went shopping for power cables. I went through several before settling on PS Audio XStream Plus's as the visual quality on the monitor was closest to that of the hacked cord. Though markl noted suffocating highs, I noticed no problems at the higher end of the visible light spectrum. My theory on the damaged cord is that the knife acts as a "sink" for the even numbered higher order harmonics off the base 60 Hz signal, which prevents them from reaching the monitor (which can alter the frequency of the photons coming off the phosphors, especially in the 600 to 700 nm range). The shielding on the XStream's must do exactly the same thing but just less effectively. The difference must be that the knife removes the harmonics, while shielding weakens but doesn't prevent them from radiating through the air. Stick to your guns markl! Jesus was scoffed for his beliefs too!
