Clark got me to thinking. The reason for fancy thick wire and expensive outlets is to lower resistance. For power amps why not use two power plugs (or even four) that would occupy an entire outlet? Of course, miswiring one of them would be an instant dead short across the power line, so they'd all have to be wired correctly.Another thought is to use a 30-amp circuit and those special plugs (which could also be doubled). Maybe if we use standard, high-current plugs, we can avoid the use of expensive "audiophile" plugs and power cords.

For that exact reason.
Most of the user experience reported concerning AC outlets and plugs points to mechanical firmness of the contacts as the limiting factor in performance. There may also be some subtle influence of the plating metallurgy, but a weak grip will mask any benefit of refined plating compositions.If contact firmness influences sonic performance, then it follows that vibration that gets to the contacts will modulate the sonic performance. This vibration is a delayed and filtered version of the music signal, so a little of it can cause a lot of trouble with what we hear.
The expensive plugs and outlets, such as Furutech and Oyaide among others, use more robust versions of the standard USA outlet design to achieve mechanical firmness. However, they are limited by the inherent weaknesses in the standard design. Inserting a dummy plug into an unused outlet of a duplex fixture improves things because it reduces the tendency of the unloaded spring contacts to vibrate. Supporting the plug or cord body, so that it does not dangle from the outlet, improves things because it reduces cord vibration influence on the contact pressure.
I can see where the 30-amp twist-lock connector could be far superior for maintaining firm contact and keeping vibration from influencing it.
My Classe CA 300 can use 13 amps at peak output (never happens) but I was bored one Saturday so I put in a 20 amp dedicated line instead of the 15 amp dedicated line and noticed subtle improvements in the sound.
