Slightly better dynamic rating (not really peak) than my Onkyo, which is rated at 100wpc (2ch driven, 8 ohm, 20hz-20khz, .08% THD) with a 120 dynamic rating at 8 ohm. Never bothered me. It doesn't have anything to do with your subs, tho. Beastly power means what, tho? I wouldn't call 100wpc beastly in any case.
