I built my own power cord using Belden 19364 and Wattgate iec and plug. In the one application where I am using it- a tubed headphone amp, this power cord had a noticeable effect in dropping background noise. I suppose that was the shielding at work.
my power cord cost about $50'for the materials, labor was on me
highly recommended
