I constructed a few DIY powercords of higher guage than the stock power cords that come with most equipement. I found there was a slight improvement, but not enough to rule out the placebo effect or other explanations for what I was hearing. When I switched to a shielded power cord, however, the difference was significant. This may be to due to excessive noise from my other components and/or the nature of the power at my house, so YMMV, but it convinced me of the benefit of a shielded power cord in my system. I am gradually replacing all the cords with shielded cords, and each time I do there is another step of improvement.
