While I have no idea exactly what power level is required, typical  
amplifiers require enough power to be worthy of a 240v circuit. A 15- 
amp 240v circuit should provide more than enough AC power to run just  
about any amplifier.

A typical 15-amp 120v circuit is only good for 1800 watts. The KPA800  
would need to have an overall efficiency of 44%, and the KPA1500  
would need 83%. The latter is not likely, and the former seriously in  
doubt.

I've had two shacks in two different houses. While I've never owned  
an amplifier, I've always wired in a 15-amp 240 volt circuit for just  
this purpose -- in case I decide to get an amp one day....
