Assuming these are nice mono amps, the idea of alterning them out of thriftiness in altering power cords seems crazy to me. You would not be able to sell these amps as being unaltered from manufacturer, and you'd take a big hit on them.
And just how would a cheaper 15A IEC guarantee that it would not alter the amps' performance in a bad way? So, with that potential reduction in sound quality you would be chasing to catch up again... Not a good plan, imo.
This is a perfect time for a PC shootout between several contenders! You have a sea change with the amp anyway; push the experiment further with a 20A cord-O-rama comparison! :)
Or, get a 15A/20A adapter for your power cords.
But what you REALLY need to do is use your stock 20A cords with some badass mongo power supply/filter device costing about $3K. That will fix everything. ;) Tee hee hee
