I suppose audio is a game of extremes. With power outputsranging from only 2.5 watts from a SET valve amprilfier to a Krell Master Reference Amplifier, with a continuous 1000 Watts at 8ohms, 2000 Watts at 4ohms, 4000 Watts at 2ohms, 8000 Watts at 1ohm, and before the two separate 220V 15amp breakers popped during clip test close to 16000 watts at .5 ohms. It was also a 300 kilogram monobloc that required 2 separate 220 v lines for best performance.
