20 Amp
I agree with the confusion over the requirement for a 20 Amp circuit so I called Emotiva CS. They told me the XPR-2 should have its own 20 amp circuit. I just had two circuits put in by an electrician -- total $238.00. Cost does not seem that much to me, but the run was only a few feet from my basement sub-panel. Now to hook it up tomorrow and see if it was all worth it. I am comparing to an Aragon 8008BB I should not have sold over a year ago. Hopefully all this is worth it as it is still less than half the price of a new Aragon from Indy labs.
