BTW, when I once had a pair of BC-2, Blue Circle Class A 75 watt monoblocks, eventhough they put out just 75 watts, the designer had recommended their own dedicated 20 amp line...which obviously I did not do. I was feeding things from a huge tube amp to other devices to the same outlet...and then, when I blew the resistors, or saw that the amp was not singing properly, I thought it was a flaw of the amp, just to later figure out that I was not providing enough amperage, watts, to the amp. It is possible that you might be also chocking the amps you are using with the Kappas. Do not put the amp on any sort of power conditioner or even strip with lights (and most likely a black transistor switch) because that will certainly mean that you are chocking off the amp from electricity. Put all amps directly into the wall receptacle. If possible, try to get yourself a dedicated amp. I think you live in a house, for the Kappas are large, therefore, something you might not have done and might be worthwhile is to make sure your outlets are "kosher" or pass the electric grade. After you are done, try the amps again and you will see. The Mac can be used for the top and the Aragon for the bottom and run for cover, you will have a good things going.
