I can say that I have a monster power pro 3500 power conditioner and it went bad at 4 years old [smoked and popped] and they sent me a new one no questions asked, my monster cables I use for my guitar are on the low end of the scale they were only 20 bucks for the 20 ft, I've had them for well over 4 years and no problems but I do take very good care of all my equipment and when I wind up a cord it is done like it came new, I don't do the hand to elbow wrap it quick as you can style, that drives me crazy to see that done to any cord or cable. Really I never paid much attention to the quality of cords but with as much as I have spent on my equipment I probably should.
