I can safely say these have no issues driving a set of King Sound III electrostatic panels with ease. I can also say that any previous issues with slow and muddy bass exhibited with early releases of the Ice modules is gone.
While the amp I have is not fully burned in yet, it has undergone at least 72 hours runtime using the Isotek burn-in disc and the amps are starting to flesh themselves out. The bass is fast and tight, clear and concise which was one of my concerns from having early Ice amps. The top end was considerably rolled off at the beginning and now is only slightly rolled off, to a point I could live with if it doesn't improve. But I'm most pleased with how well it controls the King III's. I don't feel like I have to back off the volume control at all. The King III's present a difficult load for many amps to handle, especially at higher volumes when certain high frequency notes are played for any duration of time. Using my standard test materials the Diablo's ran without a problem through areas that the other amps either went into protection mode or clipped.
I'm very pleased with the performance so far and will be extremely happy with them matched to the King's if the top end opens up even more.
Good job guys!
