20 amp

I'm redoing my HT and I picked up a few used Krell Monos (fpb350mcx, fpb250mc) and the power cord is terminated with 20 amp NEMA (see, for example, http://www.frentzandsons.com/Hardware%20References/plugandreceptacleconfiguratio.htm#20%20Amp). Is there any audiophile wall receptacle for this...
