Sorry, I need to make corrections to my post. For Audio Sensibility, the minimum 20A IEC power cord option is the Testament SE (not Statement).
That Voodoo Black Magic might be a good option because it's a huge 8awg cord which will carry a lot of current. However, it's described as "micro-fine copper conductors", which tells me it uses very tiny strands of wire (not good in my opinion). The Audio Sensibility cords all use OCC copper, which is better.
The nonoise suggestion of Cullen could be a good for the money option, but keep in mind that they use silver-plated copper and is only 4N copper (not a lot).
I just thought of another option here:

I suspect the VH Audio cables are likely the best of all the options we have discussed. The "VH Audio flavor 4" cables appear to be what you want. It's a large 9awg cord. It uses "low strand count" bundles, which tell me the individual wire strands are rather thick (good thing). I priced a 4 foot with Furutech Gold 15A male and a Furutech Gold 20A IEC for $408. It might be more than what you want to spend, but I think it's the best option in this "reasonable" area (before pricing really gets crazy)
