I just checked the ML Summit specs. The built-in woofer amp is 200W. Recommended external amp (for the panel only remember!) is 100-300W. None of the prior ML speakers had on-board amps, and thus would have employed a completely different electronic interface between the power amp and crossover -- so I feel that amp/speaker experiences w/ previous ML models must be considered anecdotal when speculating what would work best with the Summit, which is decidedly not an evolution of their previous hybrid models.
