Budget High Current Power Cords


Bang for buck, what are the best high-current power cords for power amps/sub amps? Seems an obvious question but I haven't found it in the AG archives.

Still looking for your great reviews of RCA MFF adapters…..

@bigby an earlier post says the 7 awg Pangea sound like throwing a blanket over your system. Yes, they are visually impressive, but have you compared their SOUND against other upgrade power cords, or only against the stock cords included with your amp? 
So when someone says high current cable, I'm presuming 20A connectors, and suitable gauges. Hospital grade outlets, for better clamping forces and better contact.
Like an IEC C-19 plug, or C-20 for example?

Budget 12 AWG power cord, will require a 20A circuit breaker.
