I have the Mcintosh MC501's and have pushed both the Persona's and the Tekton DI's till the power guard lights on both are blinking at me. They both stayed clean and clear which is impressive given the fact that most Mac stuff is pushing more than the actual rated power.
Clean power seems to be a huge factor. My OLD set of Maggies MG1 I think buzzed the ribbon with an old Sony ES receiver that I had with not much going through them. But recently hooked them up to the MC300 in the other room and held up well running some real wattage through them.
