Apparently the Anthem M1s, when fed by 240VAC and coupled with a pair of Model Ts, vapourized Slim's EP500v4 and EP800v4. I suppose Slim will show up here and tell you. I wonder at what level the Ts will melt. He's already pumping 2,000W into each one and the soundstage is twice the size it was when the Anthems were fed by 120VAC.
